75-982: The Nitro entered production in August 2006 aside the Liberty at the Toledo North Assembly Plant in Toledo, Ohio and was offered in a single, four-door body configuration. Like the Liberty, it was manufactured in RHD and LHD configurations, and marketed globally. Sales commenced in September 2006 for model year 2007 in rear-wheel drive or optional and part-time four-wheel drive . Approximately 200,000 Nitro models were manufactured before production ended in December 2011. The Nitro debuted in February 2005 at

150-429: 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

225-581: A TV advertisement in Europe for the Nitro with the tag line: "charged with adrenaline" , showed a dog electrocuted after lifting its leg on the SUV's front wheel. The ad received negative attention and was withdrawn. Rebadged models, mostly from Japanese or Korean manufacturers – Rebadged Chrysler/Plymouth models for external markets Toledo North Assembly Plant#Toledo North The Toledo Assembly Complex

300-508: 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

375-479: 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

450-413: 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

525-620: A moveable floor panel to slide out from the cargo area by 18 in (457 mm) to ease loading. For its debut in 2007, two-wheel and four-wheel drive were offered, along with a choice of a 3.7 L or 4.0 L V6 engines. The model designations were the SXT, SLT, and R/T. Available interior seating surfaces included cloth, stain-repellent cloth, and perforated leather. Standard safety features included front and rear side airbags, side curtain airbags, an electronic stability program with traction control and brake assist, electronic roll mitigation, and

600-463: 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

675-556: A power driver's seat, stain-repellent cloth, the Load 'N Go retractable cargo floor, cruise control, and an overhead console with a trip computer, compass, and exterior temperature display. Standard safety features include front airbags, side curtain airbags, traction and stability control with roll-over mitigation, brake assist, and a tire-pressure monitor. For the 2010 model year, three trim levels were offered: Heat, Detonator, and Shock trim levels in either 4x2 or 4x4 versions. The Heat trim

750-448: 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

825-480: A tire-pressure monitor. The four-cylinder version was sold exclusively in Europe . For the 2008 model year, the Nitro came in both 4x2 and 4x4 versions in SXT and SLT trim levels, each with a standard 210-hp 3.7 L V6 engine. The SXT trim included a standard six-speed manual transmission with an optional four-speed automatic. The SLT trim included a standard four-speed automatic. The optional R/T package increased

900-498: A trip computer, compass, and exterior temperature display. Standard safety features included front airbags, side curtain airbags, traction and stability control with roll-over mitigation, brake assist, and a tire-pressure monitor. In 2009, the Nitro was offered in both 4x2 and 4x4 versions with two trims levels: SE and SLT. Both came with a standard 210-hp 3.7 L V6 engine mated to a four-speed automatic transmission. The SXT with its six-speed manual transmission had been replaced by

975-438: A trip computer, compass, and exterior temperature display. The Shock trim added heated front seats, leather trim interior, and a power sunroof. Among standard safety features were: front airbags, side curtain airbags, active head restraints, traction and stability control with roll-over mitigation, brake assist, and a tire-pressure monitor. The Load 'N Go sliding trunk floor feature was discontinued. The 2011 model year continued

1050-666: A wholly owned subsidiary of KUKA Systems North America, which operates the body shop. Both employ their employees and control their operations. While the suppliers may make most of the parts, Chrysler does the final assembly. The Toledo Supplier Park is on the same site as the Stickney Plant. The Jeep Wrangler JK was produced at this plant until it was retooled to build the 2019 Jeep Gladiator (JT). The "Toledo North Assembly Plant" ( 41°41′46″N 83°31′10″W  /  41.69611°N 83.51944°W  / 41.69611; -83.51944  ( Toledo North Assembly Plant ) )

1125-413: Is a 3,640,000 sq ft (338,000 m ) automotive factory complex in Toledo, Ohio . Now owned by Stellantis North America , sections of the facility have operated as an automobile assembly plant since 1910, initially for Willys-Overland . The Toledo complex has assembled Jeeps since the 1940s and comprises two factories, Toledo North and Toledo South. The latter includes the Stickney Plant and

1200-577: 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

1275-521: 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

1350-404: 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

1425-452: 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

1500-457: 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

1575-565: 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

1650-513: 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

1725-450: 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

1800-403: 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

1875-660: The Chicago Auto Show as a concept with aluminum-trimmed vents door handles and rear hatch, as well as an interior with a center stack and shifter in satin silver. The Nitro became Dodge's first compact SUV model since the Raider was discontinued in 1990. It also became the first modern Dodge marketed in Europe , where the Nitro was Dodge's only SUV until the 2009 model year when the larger, car-based, lower-priced Dodge Journey crossover SUV arrived. The Nitro shares mechanicals and much bodywork with its platform-mate,

1950-633: 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

2025-475: The clutch system automatically — and use different forms of actuation (usually via an actuator or servo ) to automate the clutch, but still require the driver's input and full control to manually actuate gear changes by hand. 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.,

2100-654: 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

2175-684: The "Stickney Plant" (4000 Stickney Ave) and the "Parkway Annex" (1000 Jeep Parkway). In recent years, the Parkway facility has done basic assembly and painting of the Jeep Wrangler. The antiquated arrangement of the old operation included operations spread through a disorganized array of buildings, which required that vehicles and components be moved through multiple building levels. The final assembly of cars occurred at Stickney, but facility constraints required that bodies be painted at Parkway and then moved through tunnels and across bridges to reach

2250-424: 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

2325-406: 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

2400-472: The 2018 Jeep Wrangler (JL) Series. [REDACTED] Media related to Toledo Complex at Wikimedia Commons Download coordinates as: Automatic transmission 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

2475-425: 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

2550-534: The Corvair. 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

2625-616: The Hydra-Matic included a wide spread of ratios (allowing both good acceleration in first gear and cruising at low engine speed in top gear) and the fluid coupling handling only a portion of the engine's torque in the top two gears (increasing fuel economy in those gears, similar to a lock-up torque converter). Use of the Hydra-Matic spread to other General Motors brands and then to other manufacturers starting 1948 including Hudson , Lincoln , Kaiser , Nash , Holden (Australia), as well as Rolls-Royce and Bentley licensing production in

2700-493: The Jeep Liberty, while using a slightly extended wheelbase, the extra length split between the rear seat and cargo areas. The Nitro debuted with an SUV class-leading 5,000-pound (2,300 kg) towing capacity. Safety features such as electronic roll mitigation, traction control, and side curtain airbags, as well as a functional sliding cargo floor marketed as Load 'N Go were offered as standard equipment. The system allows

2775-746: The Parkway Annex. In 2018, Fiat Chrysler Automobiles FCA, the predecessor of Stellantis NA, announced that the Toledo Machining Plant would assemble the power electronics module and components for the Jeep Wrangler Plug-in Hybrid launched in 2020. The "Toledo South Assembly Plant" is the original Jeep CJ assembly factory. It was rebuilt to manufacture the JK Wrangler for Jeep, starting in August 2006. The plant consists of two interconnected units,

2850-580: The Parkway plant until 2006, when it was closed. Jeep Wrangler assembly was completed at the Stickney plant from 1993 until the Toledo Supplier Park opened in 2006 for the 2007 model year vehicles. The Parkway plant included landmark smokestacks spelling out "Overland" in bricks. It was home to military Jeep production and the Jeep museum. One-third of the plant was demolished in 2002, including

2925-451: The SE trim that featured the automatic transmission. The SLT trim offered the optional R/T package which was made available with a 260-hp 4.0 L V6 engine mated to a five-speed automatic transmission. The Nitro's SE trim standards included power mirrors, windows, and door locks with remote keyless entry, satellite radio, air conditioning, and seating for five. The SXT and R/T added alloy wheels,

3000-578: 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

3075-672: 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

3150-429: 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

3225-518: The assembly line. Both the Stickney and Parkway sites were replaced by Toledo Supplier Park in 2007. The Stickney Plant ( 41°41′40″N 83°31′31″W  /  41.69444°N 83.52528°W  / 41.69444; -83.52528  ( Stickney Plant / Toledo Supplier Park ) ) was opened in 1942 by Autolite and sold to Kaiser-Jeep in 1964. It was a machining and engine plant until 1981 when American Motors Corporation (AMC) converted it for vehicle production. The original Jeep Grand Wagoneer

3300-401: 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

3375-403: 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

3450-446: 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

3525-402: 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

3600-411: 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 ,

3675-564: 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. The most common type of automatic transmission is the hydraulic automatic , which uses a planetary (epicyclic) gearset , hydraulic controls , and a torque converter . Other types of automatic transmissions include continuously variable transmissions (CVT), automated manual transmissions (AMT), and dual-clutch transmissions (DCT). The 1904 Sturtevant "horseless carriage gearbox"

3750-494: 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

3825-591: 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

3900-456: The fleet market only, featured in retail brochures, but not indicated on Dodge's United States & Canada websites. The final Nitro came off the assembly line in December 2011, with a total of 175,510 (conflicts with number below) units built since its introduction. In Australia, versions could have only the 3.7 L V6 in SXT trim with automatic transmission. No manual option was offered, but diesels were on sale until 2010 MY. In early 2007,

3975-608: The former museum, and the remainder was later razed to the ground. Two of the three "Overland" smokestacks, a Toledo landmark since 1915, were demolished in June 2007. In 2010, the site was acquired by the Toledo–Lucas County Port Authority . The agency redeveloped the property as an industrial park. It includes a new Dana facility producing Jeep axles and a Detroit Manufacturing Systems plant producing instrument clusters. The remaining stack, left alone by Chrysler,

4050-433: 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,

4125-401: 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

4200-406: 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

4275-472: The level of equipment with a 260-hp 4.0 L V6 engine mated to a five-speed automatic transmission . The Nitro's SXT trim included standard power mirrors, windows, and door locks with remote keyless entry, satellite radio, air conditioning, and seating for five. The SXT and R/T added alloy wheels, a power driver's seat, stain-repellent cloth, the Load 'N Go retractable cargo floor, fold-flat front-row passenger seat, cruise control, and an overhead console with

4350-443: 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

4425-681: 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

4500-719: The previous models in 4x2 or 4x4 versions with the same engines and transmissions. New for 2011 was the Heat 4.0 lifestyle package. The Heat 4.0 came standard with a five-speed automatic transmission , Uconnect Phone, and an upgraded eight-speaker sound system. Also, select models came with upgraded interiors with new cloth and leather with premium colored stitching. Detonator and Shock were branded with Dodge Brand's signature racing stripes. Additionally, all models became available with nine exterior colors, including Bright White Clear Coat, Blackberry Pearl Coat, Toxic Orange Pearl Coat, and Redline Two Coat Pearl. Chrysler built 2012 Dodge Nitros for

4575-424: 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

4650-622: 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

4725-441: 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

4800-418: 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

4875-644: 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

4950-504: Was dedicated in August 2013, with a plaque honoring the former plants' numerous workers. Toledo Supplier Park was opened in 2007 by DaimlerChrysler to produce the new Jeep Wrangler . The name comes from the two on-site suppliers who make different parts for the Wrangler. There is Mobis North America (formerly OMMC) owned by Hyundai Mobis , which assembles the chassis, axles, and power train, and KUKA Toledo Production Operations (KTPO),

5025-439: Was equipped with a 210-hp 3.7 L V6 engine mated to a four-speed automatic transmission. The Detonator and Shock trims included a 260-hp V6 engine mated to an automatic transmission. The Heat trim level had power mirrors, windows, and door locks with remote keyless entry, satellite radio, and air conditioning. The Detonator added a rear-park assist, remote start system, power driver's seat, cruise control, an overhead console with

5100-506: 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

5175-541: 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

5250-639: 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

5325-548: 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

5400-469: Was made there from 1981 until the SJ model was discontinued in 1991. After that, Chrysler moved the final assembly of the Wrangler to this facility there. Chrysler renamed this facility to Toledo Assembly Plant after the automaker acquired AMC in 1987. The Parkway Annex ( 41°40′57″N 83°33′55″W  /  41.68250°N 83.56528°W  / 41.68250; -83.56528  ( Parkway Annex ) )

5475-562: Was opened in 1904 as a bicycle factory. Its use as an automobile assembly plant dates from 1910 when Willys-Overland purchased it. The plant began producing Jeep vehicles in the 1940s. Chrysler also renamed this factory to the Toledo Assembly Plant after acquiring AMC in 1987. Basic assembly and painting of the Jeep Cherokee (1983 through 2000) and building bodies and painting of the Jeep Wrangler by Chrysler were at

5550-666: Was opened in 2001, building the unibody Jeep Liberty . The 2,140,000 sq ft (199,000 m ) building is on 200 acres (81 ha) at 4400 Chrysler Drive. Construction began in 1997. The plant employs almost 7,000. Production of the all-new 2014 Jeep Cherokee (KL) started at the plant in 2013. In 2017, Chrysler moved production of the Cherokee KL to the Belvidere Assembly Plant in Illinois . The Toledo North Assembly Plant retooled to begin producing

5625-551: 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,
