An automatic transmission (sometimes abbreviated AT ) is a multi-speed transmission used in motor vehicles that does not require any input from the driver to change forward gears under normal driving conditions. Vehicles with internal combustion engines , unlike electric vehicles , require the engine to operate in a narrow range of rates of rotation, requiring a gearbox , operated manually or automatically, to drive the wheels over a wide range of speeds.
150-524: The Chevrolet Caprice is a full-size car produced by Chevrolet in North America for the 1965 through 1996 model years . Full-size Chevrolet sales peaked in 1965, with over a million units sold. It was the most popular car in the U.S. in the 1960s and early 1970s, which, during its production, included the Biscayne , Bel Air , and Impala . Introduced in mid-1965 as a luxury trim package for
300-429: A clutchless manual , is a type of multi-speed automobile transmission system that is closely based on the mechanical design of a conventional manual transmission , and automates either the clutch system, the gear shifting, or both simultaneously, requiring partial, or no driver input or involvement. Earlier versions of these transmissions that are semi-automatic in operation, such as Autostick , control only
450-658: A vehicle size class which originated in the United States and is used for cars larger than mid-size cars . It is the largest size class for cars. In the United Kingdom, this class is referred to as the executive car , while in Europe, it is known as E-segment or F-segment . The United States Environmental Protection Agency (EPA) Fuel Economy Regulations for 1977 and Later Model Year (dated July 1996) includes definitions for classes of automobiles. Based on
600-449: A 250 hp (186 kW) 350 cubic-inch Turbo Fire V8. Optional V8s included a 300 hp (224 kW) 350 and a new 265 hp (198 kW) 400 cu in (6.6 L) Turbo Fire V8. The top engine was a new 454 cu in (7.4 L) Turbo Jet V8 offered in 345 hp (257 kW) or 390 hp (291 kW) versions. Both the 250- and 265 hp (198 kW) Turbo Fire engines were designed to use regular gasoline while
750-462: A Federal mandate for the 1970 models, but introduced a year earlier on all General Motors cars except the Corvair . The 1969 Caprice also offered a new GM-designed variable-ratio power steering unit as optional equipment along with a seldom-ordered "Liquid Tire Chain" option, which was a vacuum activated button that would spray ice melt on the rear tires (UPC option code is "V75"). The standard engine
900-652: A comparison road test that included a Caprice Coupe and a Cadillac Sedan de Ville. The tested Caprice was powered by the 454 V8 and loaded with virtually all available options. Though testers noted that the Cadillac had a higher level of quality than the Chevrolet along with a far more luxurious interior (the DeVille was upholstered in leather while the Caprice had the standard cloth trim), the magazine ultimately considered
1050-508: A constant angular velocity while the vehicle moves at varying speeds. CVTs are used in cars , tractors , UTVs , motor scooters , snowmobiles , and earthmoving equipment . The most common type of CVT uses two pulleys connected by a belt or chain , however, several other designs have also been used. A dual-clutch transmission (DCT, sometimes referred to as a twin-clutch transmission , or double-clutch transmission ) uses two separate clutches for odd and even gear sets . The design
1200-435: A fiber optic exterior light monitoring system. The same seating selections continued as before with revisions to trim patterns plus the new addition of all-vinyl upholstery as a no-cost option for conventional and Strato bench seats in sedans and coupes. Engines and transmission offerings were carried over from the previous year. The exception was the optional 425 hp (317 kW) 427 cu in (7.0 L) Turbo Jet V8
1350-479: A form of manual transmission which removed the reliance on the driver's skill to achieve smooth gear shifts. The first automatic transmission using hydraulic fluid was developed in 1932 by two Brazilian engineers, José Braz Araripe and Fernando Lehly Lemos. The evolution towards mass-produced automatic transmissions continued with the 1933–1935 REO Motor Car Company Self-Shifter semi-automatic transmission, which automatically shifted between two forward gears in
1500-538: A full-size Chevy in the 1973 lower trim Bel Air. Standard on station wagons and optional on other Caprice models was a 145 hp (108 kW) 2-barrel 305 cu in (5.0 L) version of the Chevy's small-block V8. This was the first model year the 305 cu in had been used in a full-size Chevrolet; it was first introduced in 1976 in compact and mid-sized Chevrolet lines. A 170 hp (127 kW) 350 cu in (5.7 L) V8 with four-barrel carburetor
1650-635: A full-size, rear wheel drive police vehicle, a captive import from Australia, built by General Motors 's subsidiary Holden . The police vehicle is a rebadged version of the Holden WM/WN Caprice . The nameplate also had a civilian and police presence in the Middle East from 1999 until 2017, where the imported Holden Statesman/Caprice built by Holden was marketed as the Chevrolet Caprice in markets such as Saudi Arabia and

#17327826993411800-418: A lower cost. Into the 1970s, the same vehicles could transport up to six occupants comfortably (or eight in a station wagon), at the expense of high fuel consumption. The sales of full-size vehicles in the United States declined after the early 1970s fuel crisis. In response to the 1978 implementation of CAFE , American manufacturers implemented downsizing to improve fuel economy, with full-size vehicles as
1950-413: A manual transmission. The 1904 Sturtevant "horseless carriage gearbox" is often considered to be the first automatic transmission for motor vehicles. At higher engine speeds, high gear was engaged. As the vehicle slowed down and engine speed decreased, the gearbox would shift back to low. However, the transmission was prone to sudden failure, due to the transmission being unable to withstand forces from
2100-400: A patent was approved in the United States describing the operation of a transmission where the manual shifting of gears and manual operation of a clutch was eliminated. This patent was submitted by Henry R. Hoffman from Chicago and was titled: Automatic Gear Shift and Speed Control . The patent described the workings of such a transmission as "...having a series of clutches disposed intermediate
2250-450: A rear-facing third seat for two occupants making these cars eight-passenger models. The cargo capacity was reduced to 87 cubic feet (2,500 L), and although the station wagon could still carry a 4 ft × 8 ft (1.2 m × 2.4 m) sheet of plywood, this could now only be done with the tailgate down. The station wagons use the coil spring suspension in the rear, as for the sedans and coupes. The headlight dimmer switch
2400-408: A return to the horizontal sweep speedometer and a revised three-spoke steering wheel. An optional instrument cluster had a narrow speedometer within its opening and flanking it with engine-turned instruments in the place of warning lamps. The fuel gauge, placed next to the speedometer within its own pod in the base models, was moved to its new place next to the speedometer. A tachometer took the place of
2550-480: A revised "Astro Ventilation" system utilizing vents in the doorjambs that replaced the troublesome 1971 version that used vents in the trunk lid and turned out to be a major source of complaints to Chevy (and other GM divisions) dealers from customers. 6-way power seats, 8-track tape players, and air conditioning were optional. The Caprice models were renamed to Caprice Classic for the 1973 model year. The Kingswood Estate model with simulated wood-grain body side trim
2700-448: A separate transmission control unit . This allows for more precise control of shift points, shift quality, lower shift times and manual control. The first five-speed automatic was the ZF 5HP18 transmission , debuting in 1991 on various BMW models. The first six-speed automatic was the ZF 6HP26 transmission , which debuted in the 2002 BMW 7 Series (E65) . The first seven-speed automatic was
2850-423: A unique rear window that created a semi-fastback. This glass had sharp corners giving it three sides. This was done through a "hot-wire" bending process. The Caprice was available as either the "Sport Coupe" or as the "Landau Coupe". The Landau Coupe features a partially covered vinyl roof. Station wagon models received a new three-way tailgate for 1977; the clamshell tailgate was gone. The three-seat models featured
3000-596: A variety of colors to harmonize the interior, and the wheel featured a new "soft-grip" rim. Front seats were also re-positioned to give more legroom for taller drivers, but shorter people found the driving position awkward. The 1974 models featured a new formal, upright grille while turn signals moved from the bumper and were now inset of the dual headlights. The taillights were moved above the new 5 mph (8 km/h) rear bumper. New thick "B" pillars and fixed rear quarter opera windows were new on two-door coupes, which essentially eliminated pillar-less hardtop design much like
3150-577: Is attributed to the increasing number of electric and hybrid cars, and the ease of integrating it with safety systems such as Autonomous Emergency Braking . The efficiency, power output as a percentage of input, of conventional automatic transmissions ranges from 86 to 94%. Manual transmissions are more fuel efficient than all but the newest automatic transmissions due to their inherently low parasitic losses, typically of about 4%, in addition to being cheaper to make, lighter, better performing, and of simpler mechanical design. However, manual transmissions have

#17327826993413300-521: Is connected to the engine via a torque converter (or a fluid coupling prior to the 1960s), instead of the friction clutch used by most manual transmissions . A hydraulic automatic transmission uses planetary gearsets instead of the manual transmission's design of gears lined up along input, output and intermediate shafts. To change gears, the hydraulic automatic uses a combination of internal clutches, friction bands or brake packs. These devices are used to lock certain gears, thus setting which gear ratio
3450-404: Is in use at a given time. A sprag clutch (a ratchet-like device which can freewheel and transmits torque in only one direction) is often used for routine gear shifts. The advantage of a sprag clutch is that it eliminates the sensitivity of timing a simultaneous clutch release/apply on two planetary gearsets, simply "taking up" the drivetrain load when actuated, and releasing automatically when
3600-452: Is integrated into the engine control unit (ECU). Modern designs have replaced the centrifugal governor with an electronic speed sensor that is used as an input to the TCU or ECU. Modern transmissions also factor in the amount of load on an engine at any given time, which is determined from either the throttle position or the amount of intake manifold vacuum. The multitude of parts, along with
3750-457: Is not possible to push start a vehicle equipped with an automatic transmission with no rear pump (aside from several automatics built prior to 1970, which also included a rear pump for towing and push-starting purposes). The pressure of the ATF is regulated by a governor connected to the output shaft, which varies the pressure depending on the vehicle speed. The valve body inside the transmission
3900-565: Is often considered to be the first true automatic transmission. The first mass-produced automatic transmission is the General Motors Hydramatic four-speed hydraulic automatic, which was introduced in 1939. Automatic transmissions are also found in some heavy commercial vehicles, particularly those which are subject to intense stop/start operation such as buses and waste collection vehicles . Vehicles with internal combustion engines, unlike electric vehicles, require
4050-513: Is often similar to two separate manual transmissions with their respective clutches contained within one housing, and working as one unit. In most car and truck applications, the DCT functions as an automatic transmission, requiring no driver input to change gears. The first DCT to reach production was the Easidrive automatic transmission introduced on the 1961 Hillman Minx mid-size car. This
4200-450: Is pressurized by a pump and then directed to the appropriate bands/clutches to obtain the required gear ratio. The ATF provides lubrication, corrosion prevention, and a hydraulic medium to transmit the power required to operate the transmission. Made from petroleum with various refinements and additives, ATF is one of the few parts of the automatic transmission that needs routine service as the vehicle ages. The main pump which pressurises
4350-403: Is responsible for directing hydraulic pressure to the appropriate bands and clutches. It receives pressurized fluid from the main pump and consists of several spring-loaded valves, check balls, and servo pistons. In older automatic transmissions, the valves use the pump pressure and the pressure from a centrifugal governor on the output side (as well as other inputs, such as throttle position or
4500-478: The Chevrolet Corvair , Ford Falcon and Plymouth Valiant ), the "full-size car" designation came into wider use. In the 1960s, the term was applied to the traditional car lines of lower-price brands, including Chevrolet, Ford, and Plymouth. As a relative term, full-size cars were marketed by the same brands offering compact cars, with entry-level cars for buyers seeking the roominess of a luxury car at
4650-607: The Chrysler LH cars (Dodge Intrepid, Eagle Vision, Chrysler Concorde/New Yorker/LHS). The same year, the Buick Roadmaster was introduced, becoming the first rear-wheel drive GM model line adopted outside of Chevrolet and Cadillac since 1985; the Chevrolet Impala was returned for the 1994 model year. The 1989 Lexus LS400 luxury sedan was the first Japanese full-size car sold in North America. Following

4800-583: The Dodge Monaco ). Developed by AMC before its acquisition by Chrysler, the Premier was a version of the front-wheel drive Renault 25 adapted for North America. The Saab 9000 took a special position at the end of the 1980s, as for a long time it was the only imported car to be classified as a "large car" by the EPA. From the 1980s to the 1990s, the market share of full-size cars began to decline; along with
4950-641: The Ford LTD 's traditional full-size attributes. In 1978, Ford released a true downsized full-size car with the introduction of the 1979 Ford LTD . Chrysler responded in 1978 when it re-engineered its intermediate B-body cars, and designated them the full-size R-bodies . However, these were not true downsized cars like GM and Ford introduced. 1977 models included a four-door sedan, two-door sedan, six-passenger two-seat station wagon, and an eight-passenger three-seat station wagon. All models had window-framed doors. No hardtop models were offered. Two-door models featured

Initially developed to replace the Ford LTD Crown Victoria, the 1986 Ford Taurus was produced alongside it as the Ford mid-size model line. After largely abandoning the full-size segment for compact cars and minivans, Chrysler gained reentry into the full-size segment in 1988 with the Eagle Premier (also produced as
5250-633: The Mercedes-Benz 7G-Tronic transmission , which debuted a year later. In 2007, the first eight-speed transmission to reach production was the Toyota AA80E transmission . The first nine-speed and ten-speed transmissions were the 2013 ZF 9HP transmission and 2017 Toyota Direct Shift-10A (used in the Lexus LC ) respectively. The gear selector is the input by which the driver selects the operating mode of an automatic transmission. Traditionally

Modern versions of these systems that are fully automatic in operation, such as Selespeed and Easytronic , require no driver input over gear changes or clutch operation. Semi-automatic versions require only partial driver input (i.e.,
5700-517: The eighth-generation Hyundai Sonata , is classified by the EPA as full-size despite being marketed as a mid-size model. In 2018, the three highest-selling cars in the full-size sedan category in the United States were the Dodge Charger, Chevrolet Impala, and Chrysler 300. The large car segment has been declining in the United States accounting for 3.6% of new vehicle sales in 2021, down from 6.6% in 2016. The models in this category included

A "Tilt/Telescopic" steering wheel option could be adjusted vertically in six positions, as well as be telescoped farther out from the steering column. Coupes could also be ordered with an all-vinyl interior featuring Strato bucket seats and center console with floor shifter, storage compartment, courtesy lighting, and full instrumentation at
6000-654: The "Forward" mode (or between two shorter gear ratios in the "Emergency low" mode). Driver involvement was still required during normal driving, since standing starts required the driver to use the clutch pedal. This was followed in 1937 by the Oldsmobile Automatic Safety Transmission . Similar in operation to the REO Self-Shifter , the Automatic Safety Transmission shifted automatically between

6300-456: The 1920s to the 1950s, most manufacturers produced model lines in a single size, growing in size with each model redesign. While the length and wheelbase varied between model lines, width was a relatively constant dimension, as the American federal government required the addition of clearance lights on a width past 80 inches. In 1960, following the introduction of compact cars (such as

Car and Driver declared "Even the most jaded car critics are in fact tripping over each other trying to be the first to anoint this sedan to be the best full-sized Chevrolet ever made." Car and Driver commented on the F41 suspension option which included stiffer springs, larger sway bars, wheels, and tires to say, "It will make you think your Chevy came from
7200-424: The 1980s, automatic transmissions with four gear ratios became increasingly common, and many were equipped with lock-up torque convertors in order to improve fuel economy. Electronics began to be more commonly used to control the transmission, replacing mechanical control methods such as spring-loaded valves in the valve body. Most systems use solenoids which are controlled by either the engine control unit , or
7350-406: The 1990s, systems to manually request a specific gear or an upshift/downshift have become more common. These manumatic transmissions offer the driver greater control over the gear selection that the traditional modes to restrict the transmission to the lower gears. Use of the manumatic functions are typically achieved either via paddles located beside the steering column, or "+" and "-" controls on
7500-496: The 1996 model year, GM ended production of large rear-wheel drive sedans. By 2000, with the sole exception of the Ford Crown Victoria, Mercury Grand Marquis, and Lincoln Town Car, full-size cars had abandoned rear-wheel drive and body-on-frame construction. Instead of model lineage, the EPA "large car" definition of over 120 interior cubic feet was widely used. Initially developed for the midsize Oldsmobile Aurora ,

#17327826993417800-469: The 300 hp (220 kW) 350 Turbo Fire and both 454 Turbo Jet engines required premium fuel. A three-speed manual transmission with column shift was standard equipment as in previous years but the floor-mounted four-speed manual with Hurst shifter was dropped from the option list for 1970 as were the Strato bucket seats and center console previously offered on coupes. Automatic transmission options included
7950-417: The 302 cu in (4.9 L) V8. By the same EPA estimates, Plymouth's Gran Fury returned 13 MPG city and 18 MPG highway with the 318 V8. Performance was good when comparing the smaller 1977 Caprice to the 1976 Caprice. A 1976 350 two-bbl powered Chevrolet ran 0–60 mph in 12.9 seconds, while a 400 powered model ran 10.7 seconds. 1977 models ran 11.4 seconds to 60 mph (97 km/h) with

Car and Driver tested a 1977 Chevrolet Impala with the 350 engine and 3.08:1 axle running a 9.6 second 0–60 mph time and obtaining a 117 mph (188 km/h) top speed. The 350 was available with a 2.56:1 axle ratio and a 3.08 axle ratio which may explain the difference in performance times. The 1977 models became the number one selling car in
8250-521: The 400 Turbo Jet was rated at 260 hp (194 kW). At year's beginning, a three-speed manual transmission was standard when the model was introduced in the fall of 1970, although at mid-year, the Turbo Hydramatic transmission and variable-ratio power steering became standard equipment on all Caprice models and lower-line models fitted with a V8 engine. Chevrolet specifications included both "gross" and "net" horsepower figures in 1971, which
8400-406: The 400 Turbo-Jet engine was rated at 300 gross horsepower with and without dual exhaust, while the more accurate net figures show it rated at 206 hp (154 kW) with a single exhaust and 260 with dual exhaust. Beginning in 1972, automakers would follow SAE standard J1349 and the "net" horsepower ratings were the only advertised ratings. In its May 1971 issue, Motor Trend magazine published
8550-420: The 454 Turbo Jet lost 10 horsepower (7.5 kW), now rated at 235 hp (175 kW) Also new for 1974 were integrated lap and shoulder seat belts and an "interlock" system required the driver and front seat passengers to fasten seat belts to be able to start the engine. The interlock feature proved so unpopular that Congress rescinded it shortly after the introduction of the 1975 models. A new option this year
8700-425: The ATF is typically a gear pump mounted between the torque converter and the planetary gear set. The input for the main pump is connected to the torque converter housing, which in turn is bolted to the engine's flexplate, so the pump provides pressure whenever the engine is running. A disadvantage of this arrangement is that there is no oil pressure to operate the transmission when the engine is not running, therefore it

The engine line-up remained unchanged, but numerically lower axle ratios were used in an attempt to boost fuel economy. The 305 and 350 engines went from a standard 2.56:1 axle for 1977 (2.73:1 for wagons), to a 2.41:1 axle for 1978 (2.56:1 for wagons). An optional 3.08 axle was also available for 350 powered Caprices. The 305 V8 engine received an aluminum intake manifold which reduced engine weight by 35 pounds. A larger brake booster

Most cars use a "P–R–N–D–L" layout for the gear selector, which consists of the following positions: Some automatic transmissions, especially by General Motors from 1940 to 1964, used a layout with reverse as the bottom position (e.g. N–D–L–R or P–N–D–L–R). Many transmissions also include positions to restrict the gear selection to the lower gears and engages the engine brake . These positions are often labelled "L" (low gear), "S" (second gear) or

The 1971 through 1976 models are the largest Chevrolets built. The downsized 1977 and restyled 1991 models were awarded Motor Trend Car of the Year. Production ended in 1996. From 2011 until 2017, the Caprice nameplate returned to North America as
10350-593: The UAE. There are differing accounts of the origin of the Caprice name. One states that it was coined by Bob Lund, Chevrolet's General Sales Manager, after a classy restaurant he frequented in New York City . Another says the car was named after Caprice Chapman, the daughter of auto executive James P. Chapman. A Caprice Custom Sedan option package (RPO Z18) was offered on the 1965 Chevrolet Impala 4-door hardtop , adding US$ 200 (equivalent to $ 1,934 in 2023) to
10500-578: The UK and providing the transmission to Jensen Motors , Armstrong Siddeley and other UK manufacturers. During World War II, the Hydra-Matic was used in some military vehicles. The first automatic transmission to use a torque converter (instead of a fluid coupling) was the Buick Dynaflow , which was introduced for the 1948 model year. In normal driving, the Dynaflow used only the top gear, relying on
10650-608: The United States had automatic transmissions. Automatic transmissions have been standard in large cars since at least 1974. By 2020 only 2.4% of new cars had manual transmissions. Historically, automatic transmissions were less efficient, but lower fuel prices in the US made this less of a problem than in Europe. In the United Kingdom, a majority of new cars have had automatic transmissions since 2020. Several manufacturers including Mercedes and Volvo no longer sell cars with manual transmissions. The growing prevalence of automatic transmissions
10800-418: The United States. (In 1976, the previous generation full-size Chevrolet was the third best-seller). More than 660,000 full-size Chevrolets were produced for the 1977 model year, with the most popular model being the four-door Caprice Classic sedan (212,840 produced). By 1978 more than 1 million downsized Chevrolets had been produced. Auto publications agreed with the public reception, with Motor Trend awarding
10950-429: The abrupt gear changes. The adoption of planetary gearsets was a significant advance towards the modern automatic transmission. One of the first transmissions to use this design was the manual transmission fitted to the 1901–1904 Wilson-Pilcher automobile. This transmission was built in the United Kingdom and used two epicyclic gears to provide four gear ratios. A foot clutch was used for standing starts, gear selection
11100-410: The best-selling model in the line. The L72 427 cu in (7.0 L) 425 hp (320 kW) Turbo-Jet V8 returned to the option list after a one-year hiatus. A new 307 cu in (5.0 L) Turbo Fire V8 rated at 200 hp (150 kW) replaced the 195 hp (145 kW) 283 cu in (4.6 L) small block as the standard engine. Inside, the instrument panel was revised with
11250-416: The bumper and optional hidden headlamps . Caprice coupes now came standard with the new Astro Ventilation system, which included extra vents in the dash, and the removal of vent (wing) windows. Side marker lamps became standard on all U.S. cars and the Caprice carried over the optional white corner marker lamps at the forward edge of the fenders in addition to the amber parking lamps which were illuminated with
11400-574: The combined passenger and cargo volume, large cars (full-size cars) are defined as having an interior volume index of more than 120 cu ft (3.4 m ) for sedan models, or 160 cu ft (4.5 m ) for station wagons. From the introduction of the Ford Flathead V8 in the 1930s until the 1980s, most North American full-size cars were powered by V8 engines . However, V6 engines and straight-six engines have also been available on American full-size cars, especially until
11550-401: The complex design of the valve body, originally made hydraulic automatic transmissions much more expensive and time-consuming to build and repair than manual transmissions; however mass-production and developments over time have reduced this cost gap. To provide coupling and decoupling of the engine, a modern automatic transmission uses a torque converter instead of the friction clutch used in
11700-413: The dash, steering wheel, and door panels as well as carpeting on lower door panels on both sedans and coupes. A center front seat armrest was also featured on sedans. Station wagons now used a unique 125-inch (3,200 mm) wheelbase and were larger than ever before. Station wagons continued to use unique model names. The Kingswood Estate wagon was considered to be equivalent to the Chevrolet Caprice being
11850-404: The design featured an optional third row of forward-facing seats accessed by the rear side doors and a folding second-row seat — and could accommodate a 4 ft × 8 ft (1.2 m × 2.4 m) sheet of building material with rear seats folded. The clamshell design required no increased footprint or operational area to open, allowing a user to stand at the cargo opening without
12000-403: The disadvantage of requiring the driver to operate the clutch and change the gear whenever required. Fuel economy of course worsens with lower efficiency. Real-world tests reported in 2022 found that in typical driving manual transmissions achieved 2 to 5% better fuel economy than automatics, increasing to 20% with an expert driver. Some laboratory tests show automatics in a better light due to
12150-446: The driver locking out the higher gears) to control which ratio is selected. As the vehicle and engine change speed, the difference between the pressures changes, causing different sets of valves to open and close. In more recent automatic transmissions, the valves are controlled by solenoids . These solenoids are computer-controlled, with the gear selection decided by a dedicated transmission control unit (TCU) or sometimes this function
12300-402: The driver must change gears manually), while fully automatic versions require no manual driver input, whatsoever ( TCU or ECU operates both the clutch system and gear shifts automatically). Modern automated manual transmissions (AMT) have their roots and origins in older clutchless manual transmissions that began to appear on mass-production automobiles in the early 1930s and 1940s, prior to
12450-433: The early 2000s when the third generation Nissan Altima was bigger than the concurrent fifth-generation Nissan Maxima . The introduction of a downsized full-size car was considered quite a risk for General Motors. To help ensure the car was a success, preview clinics were held by Chevrolet that returned very positive results. Furthermore, the design process for this car was revolutionized. Ford would respond with advertising
12600-411: The engine shaft and the differential shaft and in which the clutches are arranged to selectively engage and drive the differential shaft dependent upon the speed at which the differential shaft rotates". However, it would be over a decade later until automatic transmissions were produced in significant quantities. In the meantime, several European and British manufacturers would use preselector gearboxes ,
12750-494: The engine to operate in a narrow range of rates of rotation, requiring a gearbox, operated manually or automatically, to drive the wheels over a wide range of speeds. Globally, 43% of new cars produced in 2015 were manual transmissions, falling to 37% by 2020. Automatic transmissions have long been prevalent in the United States, but only started to become common in Europe much later. In Europe in 1997, only 10–12% of cars had automatic transmissions. In 1957 over 80% of new cars in
12900-513: The first fully electric full-size car sold in North America. For the 2013 model year, the Chevrolet Impala became the final American-market full-size sedan sold with a front bench seat . By the mid-2010s, full-size cars began seeing a steep decline in sales in North America, with SUVs replacing much of the full-size segment. At the end of the decade, demand for sedans (of all sizes) shifted towards vehicles of other layouts, reducing or shuttering production of sedans entirely. In 2018, Ford announced
13050-591: The first mass-produced automatic transmission following its introduction in 1939 (1940 model year). Available as an option in cars such as the Oldsmobile Series 60 and Cadillac Sixty Special , the Hydra-Matic combined a fluid coupling with three hydraulically controlled planetary gearsets to produce four forward speeds plus reverse. The transmission was sensitive to engine throttle position and road speed, producing fully automatic up- and down-shifting that varied according to operating conditions. Features of
13200-400: The first model lines to see major change. While General Motors and Ford would reduce the exterior footprint of their full-size lines to that of their intermediates, AMC withdrew its Ambassador and Matador full-size lines (to concentrate on production of mid-size vehicles). To save production costs, Chrysler repackaged its intermediates using the erstwhile full-size names, moving on to exiting
13350-424: The four-barrel Turbo Jet 400 big-block V8 and 270 hp (201 kW) for the four-barrel dual exhaust 454 cu in (7.4 L) Turbo Jet V8 (rated at 230 hp (172 kW) in wagons with single exhaust). Turbo Hydramatic transmission, variable-ratio power steering and power front disc brakes continued as standard equipment. New to the Caprice lineup was a pillared four-door sedan. All models also featured
13500-523: The front end of the console that was integrated with the lower instrument panel. The 1965-70 GM B platform is the fourth best-selling automobile platform in history after the Volkswagen Beetle , Ford Model T , and the Lada Riva . The 1967 Caprice received a restyling with more rounded body lines and revised grilles and taillights, optional front fender corner lamps which illuminated with
13650-443: The fuel gauge in the large opening left by the fuel gauge. The 1969 Caprice and other full-sized Chevrolets were restyled with new body lines and front bumpers that wrapped around the grille (again with optional concealed headlamps, for which washers could be added as a new "one year only" option) along with ventless front windows on all models. The 119-inch (3,023 mm) wheelbase, inner bodyshell and framework were carried over from
13800-433: The gear selector is located between the two front seats or on the steering column, however electronic rotary dials and push-buttons have also been occasionally used since the 1980s, as well as push buttons having been used in the 1950s and 1960s by Rambler (automobile) , Edsel , and most famously, by Chrysler . A few automobiles employed a lever on the instrument panel, such as the 1955 Chrysler Corporation cars, and notably,
13950-401: The gear selector. Some cars offer drivers both methods to request a manual gear selection. A continuously variable transmission (CVT) can change seamlessly through a continuous (infinite) range of gear ratios, compared with other automatic transmissions that provide a limited number of gear ratios in fixed steps. The flexibility of a CVT with suitable control may allow the engine to operate at
14100-450: The headlamps, as well as a revised instrument panel with round instruments and a new steering wheel. Taillamp lenses were all red as the backup lamps were relocated into the rear bumper, unlike in the lesser full-size models that had their backup lamps in the center of the taillamps. A dual-master brake cylinder was now included, while front disc brakes were optional. Other new options included a stereo 8-track tape player, power door locks, and
14250-496: The headlights. All 1968 Chevrolets got front side marker lamps on the fender; cars with an optional engine were identified with its cubic inch displacement listed on half the bezel; the lamp itself occupied the other half. The fiber optics monitoring system was offered again as an option. The Caprice Coupe got serious competition when Chevrolet offered the car's formal roofline in the Impala series as well. The Impala Custom Coupe became
14400-548: The impediment of a door — for example, in a closed garage. The Kingswood Estate had the 400 cu in (6.6 L) two-barrel engine as standard with the same engine options as the coupes and sedans. Station wagon models came only with single exhaust systems which meant lesser power ratings than coupes and sedans. Power front disc brakes were standard equipment, along with a larger 255 hp (190 kW) gross (170 hp (127 kW) net) 400 cubic-inch Turbo Fire V8 . This engine, along with all optional power plants,
14550-511: The increased use of mid-size cars, vans, and SUVs grew in use as family vehicles. Between 1960 and 1994, the market share of full-size cars declined from 65 to only 8.3 percent. From 1990 until 1992, both GM and Ford redesigned its full-size car lines for the first time since the late 1970s. For the 1992 model year, Chrysler introduced a new front-wheel drive full-size car line, replacing the Eagle Premier/Dodge Monaco with
14700-406: The introduction of hydraulic automatic transmissions. These systems were designed to reduce the amount of clutch or gear shifter usage required by the driver. These devices were intended to reduce the difficulty of operating conventional unsynchronised manual transmissions ("crash gearboxes") that were commonly used at the time, especially in stop-start driving. An early example of this transmission
14850-416: The last was not available in California. All engines except for the 454 were single exhaust systems with the introduction of the catalytic converter. Station wagons that used the 454 now featured dual exhaust as well. Also introduced this year were GM's "High Energy" electronic ignition and radial tires that were advertised as part of "Chevrolet's New Efficiency System." The theme of economy continued through to
15000-497: The most changed full-size Chevrolet to date. The weight reductions from the 1976 models were 611 lb (277 kg) for coupes, 637 lb (289 kg) for sedans and 871 lb (395 kg) for wagons. The 1977 Caprice coupe and sedan were over 10 inches (250 mm) shorter while the wagon was 14 inches (360 mm) shorter. Wheelbases were reduced to 116 inches (2,900 mm) from 121.5 inches (3,090 mm) for coupes and sedans and 125 inches (3,200 mm) for wagons. Width
15150-475: The new Chevrolet had exterior dimensions closer to the intermediates of its day. The 1977 Caprice shared the same 116-inch (2,900 mm) wheelbase of the intermediate-sized Chevrolet Chevelle; 1977 also marked the first model year in history that a midsized car, the Monte Carlo, was larger than a full-sized car; this would be repeated in the 1980s by GM and Chrysler on multiple vehicles, then by Nissan in
15300-404: The new options this year: A new "Econominder" gauge package included a temperature gauge and a "fuel econominder", the second being a gauge alerting drivers as to when their driving habits caused the engine to use more or less fuel. Also new on the options list: intermittent windshield wipers, and 50/50 seating options on the Impala coupe/sedan and Caprice Classic convertible models. "Landau" model
15450-443: The next gear's sprag clutch assumes the torque transfer. The friction bands are often used for manually selected gears (such as low range or reverse) and operate on the planetary drum's circumference. Bands are not applied when the drive/overdrive range is selected, the torque being transmitted by the sprag clutches instead. The aforementioned friction bands and clutches are controlled using automatic transmission fluid (ATF), which
15600-681: The number of the highest gear used in that position (eg 3, 2 or 1). If these positions are engaged at a time when it would result in excessive engine speed, many modern transmissions disregard the selector position and remain in the higher gear. In descending order of the highest gear available: Many modern transmissions include modes to adjust the shift logic to prefer either power or fuel economy . "Sport" (also called "Power" or "Performance") modes cause gear shifts to occur at higher engine speeds, allowing higher acceleration. "Economy" (also called "Eco" or "Comfort") modes cause gear shifts to occur at lower engine speeds to reduce fuel consumption. Since
15750-454: The other full-sized models. Sedans and coupe models included luxurious cloth and vinyl bench seats with a folding center armrest in the rear seat. Optional on both was a "Strato bench" seat which combined bucket-style seat backs and a center armrest with a bench cushion for six-passenger seating. Caprices had unique standard wheel covers, although some of the optional wheels and wheel covers on full-sized models were optional. New options included
15900-571: The package. With minor changes, the Landau model would be carried over into the 1977 generation coupe models. The 1976 Caprice Classic marked the sixth and final year of a body style introduced for the 1971 model year. 1976 models weighed approximately 4,314 pounds (1,957 kg) and was 222.9 inches (5,660 mm) long, growing considerably from the 1971s 4,040 pounds (1,830 kg) and 216.8-inch (5,510 mm) length. Only minor changes were made for 1976, including an eggcrate grille similar to that of
16050-532: The roof and the lower tailgate (with either manual or optional power operation), lowered completely below the load floor. The manual lower tailgate was counterbalanced by a torque rod similar to the torque rods used in holding a trunk lid open, requiring a 35 lb push to fully lower the gate. Raising the manual gate required a 5 lb pull via a handhold integral to the top edge of the retractable gate. The power operation of both upper glass and lower tailgate became standard equipment in later model years. Wagons with
16200-578: The sales of all Ford-branded passenger cars (except for the Mustang ) would end in North America by 2022. General Motors announced the closure of several manufacturing facilities in the United States and Canada, with the production of the Chevrolet Impala and Buick LaCrosse ending in 2020. As of 2022, full-size cars from Asian manufacturers include the Lexus LS , Genesis G80 / G90 , Nissan Maxima , and Toyota Avalon . Another car from an Asian manufacturer,
16350-570: The same bore and stroke as the 305 cu in V8. California emission cars used the Buick 3.8 L (231 cu in) V6 engine. The Chevrolet 3.8 L was rated at 115 hp (86 kW) while the Buick V6 engine had a 110 hp (82 kW) rating. Although the 3.8 L V6 had the same horsepower rating as the 250 six used in 1979, the 250 had 25 lb⋅ft (34 N⋅m) more torque than
16500-535: The segment in 1981. During the 1980s, manufacturers further reduced the exterior footprint of several model lines from the full-size segment into the mid-size class to comply with more stringent CAFE standards. With the 1982 model year, Chrysler exited the full-size segment entirely, with the mid-size Dodge Diplomat and Plymouth Gran Fury serving as its largest sedan lines. Following the 1985 model year, General Motors replaced most of its full-size rear-wheel-drive model lines with smaller front-wheel drive sedans on
16650-418: The smaller Rochester Dualjet carburetor. The 350 engine was unchanged. The 1980 Caprice Classic saw its first major revision since the 1977 downsizing. To further improve the fuel economy of the car, efforts were made to reduce weight and improve aerodynamics. The Caprice received new exterior sheet metal, without drastically changing the look of the car. To improve aerodynamics the hood was tapered lower, while
16800-508: The speedometer read up to 100 mph (160 km/h), and had smaller numbers for kilometers per hour. The Caprice convertible would be discontinued after the 1975 model year along with its full-size B-body counterparts including the Oldsmobile Delta 88 , Buick Centurion , and Pontiac Grand Ville . Just about 8,350 Caprice Classic convertibles found buyers in 1975. As fuel economy became a bigger priority among Americans following
16950-424: The tests using a prescribed shifting pattern for manuals not always optimized for economy. However, on long highway journeys manual transmissions require maintaining a very specific cruising speed to optimise economy, making automatics preferable. The most common design of automatic transmissions is the hydraulic automatic, which typically uses planetary gearsets that are operated using hydraulics. The transmission
17100-471: The three-speed Turbo Hydramatic transmission for the first time though the two-speed Powerglide was still offered with the 327 and 350 V8s. The 1970 Caprice received a minor facelift featuring a more conventional under the grille bumper replacing the wrap-around unit used in 1969, along with new triple vertical taillamps in the rear bumper. Power front disc brakes and fiberglass-belted tires on 15-inch (380 mm) wheels were made standard equipment along with
17250-494: The top-level wagon. Unlike previous years, station wagons used unique rear suspension using a solid axle with leaf springs as opposed to coil springs and trailing arms on sedans and coupes. Wagons featured a "clamshell" design marketed as the Glide-away tailgate, also called a "disappearing" tailgate because when open, the tailgate was completely out of view. On the clamshell design, the rear power-operated glass slid up into
17400-622: The torque multiplication of the torque convertor at lower speeds. The Dynaflow was followed by the Packard Ultramatic in mid-1949 and the Chevrolet Powerglide for the 1950 model year. Each of these transmissions had only two forward speeds, relying on the converter for additional torque multiplication. In the early 1950s, BorgWarner developed a series of three-speed torque converter automatics for car manufacturers such as American Motors, Ford and Studebaker. Chrysler
17550-418: The trunk area was higher. The grille was now an egg crate style while the tail-light panel featured three separate square lights per side. All the doors and components within were redesigned to be lighter, including the window-crank mechanisms, which now used a tape-drive mechanism. Greater use of aluminum including in-bumper reinforcement and in-sedan/coupe radiators helped to further reduce the overall weight of
17700-441: The two gear ratios available in the "Low" and "High" ranges and the clutch pedal was required for standing starts. It used a planetary gearset. The Chrysler Fluid Drive , introduced in 1939, was an optional addition to manual transmissions where a fluid coupling (similar to a torque-convertor, but without the torque multiplication) was added, to avoid the need to operate a manual clutch. The General Motors Hydra-Matic became
17850-405: The two-speed Powerglide on 350 V8s and Turbo Hydra-Matic with all engines. For 1971 the top-of-the-line Caprice was completely redesigned on a longer 121.5-inch (3,090 mm) wheelbase and featured bold, Chrysler-like fuselage styling. Flush exterior door handles and double-shell roofs were new on the Caprice – both features first appearing on the 1970½ Camaro and Pontiac Firebird. The new styling
18000-438: The vehicle. 1980 models were approximately 100 pounds (45 kg) lighter than 1979 models. The new styling increased the trunk capacity of both coupes and sedans to 20.9 cubic feet (592 L). This increase was also partially achieved with a now-standard compact spare tire on a 16-inch (410 mm) wheel. A new frame lift jack replaced the bumper-mounted model. A larger 25 US gallons (95 L; 21 imp gal) fuel tank
18150-413: Was 17 miles per US gallon (14 L/100 km; 20 mpg ‑imp ) city and 22 miles per US gallon (11 L/100 km; 26 mpg ‑imp ) highway for six-cylinder models. Ford's 1977 LTD was rated at 15 miles per US gallon (16 L/100 km; 18 mpg ‑imp ) city and 19 miles per US gallon (12 L/100 km; 23 mpg ‑imp ) highway with its smallest engine,
18300-475: Was a Synchro-Mesh three-speed manual, mounted on the steering column. It remained standard throughout this generation. The 1966 Caprice featured a revised grille and front bumper, and new rectangular taillights which replaced the Chevrolet-traditional triple round taillights used on Impalas since 1958, with the exception of the 1959 model. Lenses and silver trim on Caprices differed slightly from
18450-546: Was a light blue metallic 1967 Caprice coupe. It was assembled on April 21, 1967, at the Janesville, Wisconsin plant. It was actually the 100 millionth GM car built in the United States; production including Canadian plants had actually passed the 100 million mark in March 1966, with an Oldsmobile Toronado being the car in question. The 1968 Caprice received a minor facelift that included a new grille with taillights set into
18600-478: Was a remote control for the passenger-side outside rear-view mirror . The 1975 models received a new front end with swept-back headlights, revised grille, and turn signals returned to the bumper which also angles backward at both ends. New taillights now wrap around rear fenders. Caprice Classic Sport sedans now feature opera windows in the C-pillars. The dashboard, radio and climate control graphics were revised;
18750-412: Was a year before the industry-wide transition to SAE net horsepower figures. SAE net horsepower standardized horsepower ratings in accord with SAE standard J1349 figures to get a more accurate horsepower figure. "Net" horsepower was measured "as installed" in a vehicle with power using accessories and emission equipment installed, exhaust systems, and air cleaners, leading to lower power ratings. For 1971,
18900-484: Was also added to help reduce braking effort. New options included a steel sliding moonroof and 40-channel CB radio built into the AM/FM radio. The 1979 models continued with only minor refinements. Again the front and rear styling was refreshed slightly. The 250 six gained five horsepower, while the 305 V8 lost 15 hp (11 kW). The change to the 305 was a result of switching from the larger Rochester 2GC carburetor to
19050-444: Was also introduced in 1975, and was primarily an appearance package. Carried over unchanged into 1976, the Landau featured a choice of special paint colors, sports-styled dual remote outside rear-view mirrors, color-keyed wheel covers, a landau vinyl roof (with chrome band across the roof), a vinyl bodyside molding insert, and pinstriping. Inside there were color-keyed seat belts and floor mats. Fender and dashboard emblems rounded out
19200-423: Was also removed from the floor and incorporated into the turn signal lever for all 1977 models. All 1977 models were named Caprice Classics. A V8 engine was no longer standard equipment for the first time since 1965. The base engine for 1977 Chevrolet Caprice coupes and sedans was Chevy's long-running 250 cu in (4.1 L) I6 engine rated at 110 hp (82 kW). This engine was previously available in
19350-418: Was among the first to have the basic gear selections ( park , reverse , neutral , drive , low ) which became the standard gear selection used for several decades. By the late 1960s, most of the fluid-coupling two-speed and four-speed transmissions had disappeared in favor of three-speed units with torque converters. Also around this time, whale oil was removed from the automatic transmission fluid. During
19500-644: Was called the Controlled Coupling Hydra-Matic , or "Jetaway" transmission. The original Hydra-Matic remained in production until the mid-1960s at GM, with the licensed Rolls-Royce Automatic transmission soldiering on until 1978 on the Rolls-Royce Phantom VI . In 1964, General Motors released a new transmission, the Turbo Hydramatic , a three-speed transmission which used a torque convertor. The Turbo Hydramatic
19650-726: Was designed to run on regular leaded, low-lead or unleaded gasoline of 91 research octane or higher. To achieve this, all engines had the compression ratios lowered to 8.5:1. General Motors was the first of the big three to have all engines run on regular fuel and these changes were made to help meet the increasingly stringent emission regulations that were to come into place in years to come. Optional engines included 300 horsepower (206 net) 402 cubic-inch Turbo Jet V8 (marketed as "Turbo Jet 400 on full-size cars, and as "Turbo Jet 396 on intermediate cars) and 365 hp (272 kW) gross (285 hp (213 kW) net) 454 Turbo Jet V8 which came standard with dual exhaust. When equipped with dual exhaust,
19800-502: Was done by a bumper within the bumper design. Heavy gauge beams reinforced the bumper and attached to the frame. The rear bumper also featured this design and now had the triple taillights now mounted in the bumper. Engine offerings were carried over from 1971 with the switch to "net" horsepower ratings including 170 hp (127 kW) for the standard two-barrel 400 cu in (6.6 L) Turbo Fire V8, 210 hp (157 kW) (240 hp (179 kW) with optional dual exhaust) for
19950-478: Was enlarged to a 235 hp (175 kW) 327 cu in (5.4 L) V8 with optional engine choices including a new 350 cu in (5.7 L) Turbo Fire V8 in 255 or 300 hp (220 kW) versions, a 265 hp (198 kW) 396 cu in (6.5 L) cubic-inch Turbo Jet V8, as well as a 427 cu in (7.0 L) cubic-inch Turbo Jet V8s rated at 335 hp (250 kW) or 390 hp (291 kW). All V8 engines were now available with
20100-506: Was followed by various eastern European tractors through the 1970s (using manual operation via a single clutch pedal), then the Porsche 962 C racing car in 1985. The first DCT of the modern era was used in the 2003 Volkswagen Golf R32 . Since the late 2000s, DCTs have become increasingly widespread, and have supplanted hydraulic automatic transmissions in various models of cars. Automated manual transmission (AMT) , sometimes referred to as
20250-615: Was highlighted by a Cadillac-like "egg-crate" grille with a "Caprice" emblem in the center and brushed metal trim surrounding the taillights on the rear deck. The "Full-Perimeter" frame and all-coil suspension were refined for improvements in ride and noise reduction. Inside were revised interiors featuring a two-spoke cushioned steering wheel and new instrument panel with horizontal sweep speedometer and instrument placement similar to previous full-sized Chevrolets. Caprices continued with higher grade interiors than their Impala counterparts with luxurious cloth-and-vinyl upholstery, wood grain trim on
20400-541: Was introduced in the 1955 Citroën DS , which used a 4-speed BVH transmission. This semi-automatic transmission used an automated clutch, which was actuated using hydraulics . Gear selection also used hydraulics , however, the gear ratio needs to be manually selected by the driver. This system was nicknamed Citro-Matic in the U.S. The first modern AMTs were introduced by BMW and Ferrari in 1997, with their SMG and F1 transmissions, respectively. Both systems used hydraulic actuators and electrical solenoids , and
20550-639: Was introduced with the Hudson Commodore in 1942, called Drive-Master . This unit was an early semi-automatic transmission , based on the design of a conventional manual transmission, which used a servo -controlled vacuum -operated clutch system, with three different gear shifting modes, at the touch of a button; manual shifting and manual clutch operation (fully manual), manual shifting with automated clutch operation (semi-automatic), and automatic shifting with automatic clutch operation (fully automatic). Another early example of this transmission system
20700-548: Was late in developing its own true automatic, introducing the two-speed torque converter PowerFlite in 1953, and the three-speed TorqueFlite in 1956. The latter was the first to utilize the Simpson compound planetary gearset. In 1956, the General Motors Hydra-Matic (which still used a fluid coupling) was redesigned based around the use of two fluid couplings to provide smoother shifts. This transmission
20850-599: Was no longer listed, leaving the 385 hp (287 kW) 427 as the top engine. The three-speed Turbo Hydramatic transmission that previously only available with the 396 cu in (6.5 L) and 427 cu in (7.0 L) V8s was now optional with the 275 hp (205 kW) 327 cu in (5.4 L) Turbo Fire V8. As with all 1967 cars sold in the U.S., Caprices featured occupant protection safety features that included an energy-absorbing steering column, soft or recessed interior control knobs, and front outboard shoulder belt anchors. The "100 millionth GM car"
21000-577: Was now named the Caprice Estate. The convertible was moved from the Impala to the Caprice lineup for the first time in 1973. The 1973 facelift included a new cross-hatch grille, 5 mph (8 km/h) energy-absorbing front bumper and revised square taillights, again mounted in the bumper. New emission standards added EGR ( exhaust gas recirculation ) valves to engines (with a new roller camshaft), and horsepower ratings were reduced. The standard Turbo-Fire 400 cu in (6.6 L) two-barrel
21150-461: Was now rated at 150 hp (112 kW) while the only optional engine was the Turbo-Jet 454 cu in (7.4 L) V8 produced 245 hp (183 kW) with dual exhaust 215 hp (160 kW) with single exhaust used in station wagons. A new option on sedans and coupes was a 50/50 bench seat with recliner on the passenger side. The instrument panel and steering wheel were now offered in
21300-412: Was now the top engine offering as the larger 400 cu in (6.6 L) and 454 cu in (7.4 L) V8s were discontinued. Standard for all models was the three-speed Turbo Hydra-Matic automatic transmission. With the new lighter weight and smaller engines, Chevrolet promised increase fuel economy without great loss of performance compared to 1976 models. The EPA estimates for 1977 Chevrolet
21450-502: Was offered in both the Caprice Classic and Impala series. All subsequent Caprice passenger cars were pillared sedans and coupes. Launched in late September 1976, the 1977 Caprice Classic was drastically downsized , which reduced its weight and exterior dimensions, while increasing headroom, rear-seat legroom and trunk space compared to 1976 models. GM called its downsizing program Project 77 and invested $ 600 million to develop
21600-420: Was reduced by 4 inches (100 mm) for sedans and coupes; the wagon's width remained virtually unchanged. Heights were increased by 2.5 inches (64 mm) and trunk capacities were increased to 20.9 cubic feet (0.59 m) for sedans and 19.8 cubic feet (0.56 m) for coupes. Size comparison between 1976 and 1977 Caprice : Although by modern standards, the 1977 downsized Chevrolet cars are quite large,
21750-437: Was standard equipment in sedans and coupes. Easy-roll radial tires, improved anti-corrosion measures, low-friction ball joints, and larger front-suspension bushings were also new for 1980. Puncture-sealant tires and cornering lights were new options. The 250 cu in (4.1 L) six was replaced by a new 90-degree Chevrolet 3.8 L (229 cu in) V6 as the base engine for sedans and coupes. This engine shared
21900-645: Was standard for Caprice models with the 325 hp (242 kW) 396 cu in (6.5 L) "Turbo Jet" V8 optional. It was possible to have Regular Production Option (RPO) L72, a 425-hp big block V8 with solid lifters, special camshaft and carburetor, and 11 to 1 compression. An automatic transmission , power steering , white sidewall tires, and a vinyl top (on the hardtops) were extra-cost options, but most were built with them. Additionally, air conditioning , power windows , Cruise-Master speed control, power seats , an automatic headlight dimmer (1965 only) and stereo radios were available. The standard transmission
22050-420: Was standard, as was a column-mounted shifter for the three-speed manual transmission. The Caprice was intended to compete with the Ford LTD , Plymouth VIP , and AMC's Ambassador DPL . These models included luxuriously upholstered interiors with simulated wood dashboard and door-panel trim, thicker carpeting, sound insulation, courtesy lighting, and more upscale exterior trims. Caprice gained series status for
22200-401: Was still unavailable in California. Also available was the 180 hp (134 kW) four-barrel 400 V8 standard on wagons and optional on all other models. This was the final year for the big block 454 V8 to be offered, along with hardtop body styles and the clam shell-tailgate design for the station wagon. The 1976 4-door hardtop Sport Sedan was the last pillarless model offered by Chevrolet; it
22350-538: Was the first Chevrolet with such a design since its real woodie wagon was offered in 1954 on the Chevrolet Bel Air . All wagons included an all-vinyl upholstered two-row bench seat interior with an optional third rear-facing seat for two. The Custom Estate became the full-sized station wagon when the Buick LeSabre Estate was discontinued in 1964. The 283 cu in (4.6 L) V8 engine
22500-551: Was using a hand lever, helical gears were used (to reduce noise) and the gears used a constant-mesh design. A planetary gearset was also used in the 1908 Ford Model T , which was fitted with a two-speed manual transmission (without helical gears). An early patent for the automatic transmission was granted to Canadian inventor Alfred Horner Munro of Regina in 1923. Being a steam engineer, Munro designed his device to use compressed air rather than hydraulic fluid , and so it lacked power and never found commercial application. In 1923,
