Mercon represents a series of technical standards for automatic transmission fluid , developed and trademarked by Ford Motor Company . This designation serves as a mark of quality that Ford has established for fluids used in automatic transmissions. The Mercon name, which has evolved into a brand, is licensed by Ford to various manufacturers. These companies are authorized to produce the fluid according to Ford's specifications and market it under their own brand names.
74-521: The specifications outlined under the Mercon label cover various aspects such as viscosity, friction characteristics, and thermal stability, which are essential for the transmission fluid to perform under a wide range of operating conditions. This careful regulation ensures that all licensed Mercon fluids provide consistent quality and performance, giving consumers confidence in their use of aftermarket products. The original Mercon (M2C185-A) Transmission Fluid
148-415: A fluid coupling , conventional clutch, and semi-automatic three-speed transmission. The transmission had an overrunning clutch on the transmission countershaft. The flywheel's fluid coupling used S.A.E 10 motor oil for lubrication. The transmission gearbox used traditional gear oil. This transmission was only produced for a few months before the U.S.A. entered World War II , production of this transmission
222-536: A trademark and later evolved into a brand of GM. GM licenses the name and specifications to companies that manufacture the fluid and sell it under their own brand names. Not all DEXRON fluids are licensed by GM for reselling under another brand name. To be licensed, the product must have a license number that begins with the letters B through J and include a "DEXRON Approved" sticker on its container. Like many automobile manufacturers, GM uses transmissions sourced from other suppliers or transmission manufacturers around
296-470: A 2018 Ford F-150 with "Lifetime Fluid" could have three different fluid service intervals depending on how the vehicle is driven: 1. Normal Driving Backward compatibility In telecommunications and computing , backward compatibility (or backwards compatibility ) is a property of an operating system , software, real-world product, or technology that allows for interoperability with an older legacy system , or with input designed for such
370-520: A console. This also helps to make up for lack of titles at the launch of new systems, as users can pull from the previous console's library of games while developers transition to the new hardware. Moreover, studies in the mid-1990s found that even consumers who never play older games after purchasing a new system consider backward compatibility a highly desirable feature, valuing the mere ability to continue to play an existing collection of games even if they choose never to do so. Backward compatibility with
444-579: A license number on the can that began with the letter H. This fluid specification and licensing program was inactivated in March 2011. The ATF Type III (H) fluid shown in the photograph is ACDelco's non-licensed fluid, which is used to support older transmissions that still required the DEXRON-III (H) fluid. This fluid is backward compatible with all previous Dexron fluids as well as the Type "A" suffix "A" and
518-479: A license number on the can that begins with the letter F. This fluid is backward compatible with all previous DEXRON fluids as well as the Type "A" suffix "A" and the Type "A" fluids produced from 1949 to 1966. In 1994–1995, some early OBD-II phase-in vehicles experienced a P0300 DTC (random misfire). Engineers determined that road forces being transferred through the TCC were affecting the normal rotational fluctuations of
592-578: A license number on the container that begins with the letter C. This was the first GM ATF to advertise 50,000 miles between changes. This fluid is backward compatible with all previous DEXRON fluids as well as the Type "A" Suffix "A", and the Type "A" fluids produced from 1949 to 1966. In 1975, GM released the DEXRON-II(D) specification (GM6032M). DEXRON-II(D) was composed of Group 2 base oil plus an additive package with alternative corrosion and rust inhibitors. The revised corrosion and rust inhibitors made
666-563: A license number on the container. If no license number is found, the fluid may not be Ford-approved and the automatic transmission fluid cannot be guaranteed to meet Ford specifications. Ford, like many automobile manufacturers, uses transmissions sourced from other suppliers or transmission manufacturers around the world; these transmissions are not manufactured by Ford. Many of these automatic transmissions use unique fluids that might not be shown on this page. In 1942, The Mercury 8 and Lincoln offered cars with an optional "Liquamatic Drive" using
740-498: A long time in normal driving conditions (Typically 100,000 miles (160,000 km) or more). The definition of 'Lifetime Fluid" differs from transmission manufacturer to transmission manufacturer. Always consult the vehicle maintenance guide for the proper service interval for the fluid in your transmission and your driving conditions. 2018 Ford F-150 Example: According to the Scheduled Maintenance Guide of
814-483: A manufacturer decides to stop supporting older hardware. Classic video games are a common example used when discussing the value of supporting older software. The cultural impact of video games is a large part of their continued success, and some believe ignoring backward compatibility would cause these titles to disappear. Backward compatibility also acts as a selling point for new hardware, as an existing player base can more affordably upgrade to subsequent generations of
SECTION 10
#1732801228591888-489: A market for older fluids that claim to meet the earlier fluid specifications. See the details below for the backward compatibility of each fluid. Originally the name MERCON was associated exclusively with automatic transmission fluids, later Ford released MERCON Gear oils and other lubricants under the MERCON brand. Not all Mercon fluids are licensed for reselling under another brand name. All licensed Mercon fluids must have
962-626: A qualification procedure to eliminate unsatisfactory fluids and, at the same time, provide the car owner with a means of identifying qualified fluids. The GM ATF Committee released a new Type "A" fluid specification. GM partnered with the Armour Research Foundation for fluid and qualification testing. Fluids that met the GM qualification requirements were issued an Armour Qualification (AQ) license number of AQ-ATF-xxx. Example (AQ-ATF-101). The license number had to be displayed on
1036-563: A result of the 1973 OPEC Oil Embargo and fuel shortages, the U.S. government created the Corporate Average Fuel Economy (CAFE) regulations in 1975. The regulations were to be fully implemented by the 1978 model year. The automotive industry responded by changing to three typically unused transmission technologies: The 1978 introduction of the TCC led to customer complaints of a shudder while driving. All vehicle manufacturers made changes to their ATF specifications and
1110-452: A system. Modifying a system in a way that does not allow backward compatibility is sometimes called " breaking " backward compatibility. Such breaking usually incurs various types of costs, such as switching cost . A complementary concept is forward compatibility ; a design that is forward-compatible usually has a roadmap for compatibility with future standards and products. A simple example of both backward and forward compatibility
1184-479: Is a general notion of interoperation between software pieces that will not produce any errors when its functionality is invoked via API . The software is considered stable when its API that is used to invoke functions is stable across different versions. In operating systems, upgrades to newer versions are said to be backward compatible if executables and other files from the previous versions will work as usual. In compilers , backward compatibility may refer to
1258-464: Is an additive package for an updated friction modifier and with an oxidatively stable base oil (group 2). Oils according to this specification have longer maintenance of friction properties and anti-shudder properties, better foam control, and a longer fluid life. universal for all automatic transmissions with and without controlled torque converter lockup clutch, the so-called GKÜB for gear-clutch-lock. GM DEXRON-III (H) licensed products prior to 2011 had
1332-534: Is particularly important in computer instruction set architectures , two of the most successful being the IBM 360 / 370 / 390 / Zseries families of mainframes, and the Intel x86 family of microprocessors . IBM announced the first 360 models in 1964 and has continued to update the series ever since, with migration over the decades from 32-bit register/24-bit addresses to 64-bit registers and addresses. Intel announced
1406-463: Is the first of many Ford “lifetime” fluids. The 1974 Ford Car Shop Manual reads "The automatic transmission is filled at the factory with "lifetime" fluid. If it is necessary to add or replace fluid, use only fluids that meet Ford Specification M2C33F. In 1972, Ford of Europe introduced a new fluid specification, the Type-G fluid (M2C33-G). This fluid was used through 1981. This fluid was first used in
1480-466: Is the introduction of FM radio in stereo . FM radio was initially mono , with only one audio channel represented by one signal . With the introduction of two-channel stereo FM radio, many listeners had only mono FM receivers. Forward compatibility for mono receivers with stereo signals was achieved by sending the sum of both left and right audio channels in one signal and the difference in another signal. That allows mono FM receivers to receive and decode
1554-488: Is the latest fluid to date. GM has upgraded the DEXRON's specifications over time. The newer fluids are not always backward-compatible with previous fluids. Newer 6, 8, 9, and 10-speed transmissions, as well as plug-in hybrid (PHEV) and electric vehicle (EV) transmission technologies, require specialized fluids to operate properly. There remains a market for older fluids that claim to meet the earlier fluid specifications. See
SECTION 20
#17328012285911628-448: Is to replace the original Mercon fluid. This fluid was first used in the following transmissions: The Mercon "V" specification was revised in 2002 (M2C919-E). This revised fluid was first used in the following transmissions: In August 2001, Ford released the Mercon "SP" fluid specification (M2C919-D). Ford SSM 21114 (November 26, 2009) indicates that Mercon Replace "SP" is to be replaced with Mercon LV on Torqshift transmissions from
1702-626: The Hydra-Matic 4-speed automatic transmission and its special Hydra-Matic Automatic Transmission Fluid , Ford released their first fully automatic transmission; the 1951 Fordomatic 3-speed transmission. This new fully automatic transmission used the GM Type "A" automatic transmission fluid specification. Ford and hundreds of other resellers, became a licensed reseller of the GM Type "A" fluid with an Armor Qualification number. The Type "A" fluid
1776-479: The 2003 through 2008 model years. This SSM does not apply to the ZF 6HP26 transmission. This fluid first used in the following transmissions: In December 2005, Ford released the Mercon "LV" fluid specification (M2C938-A). This fluid was first used in the following transmissions: This specification was revised in 2007 for use in the following transmissions: This specification was revised again in 2010 (M2C938-A2) and
1850-427: The GM Type "A" fluid. In 1952, Chrysler released their 1953 Powerflite 2-speed transmission, which also used GM Type "A" fluid. This fluid was first used in the following transmissions: In 1957, GM released a new Type "A" Suffix "A" fluid specification. This fluid was better suited for the higher fluid temperatures caused by the unique torque converters and higher power engines of the day. The fluid specification
1924-474: The GM Type "A" suffix "A" fluid. This fluid was first used in the following transmissions: DEXRON (B) was released on April 1, 1967. The original fluid better retained the initial properties of the previous Type "A" Suffix "A" fluid (Several thousand cycles compared to 1000 cycles). DEXRON (B) was composed of a more stable, less reactive, hydrotreated Group 1 base oil plus additives to help prevent foaming, oxidation, and damage from elevated temperatures. This
1998-459: The Type "A" fluid, in 1949. The Hydra-Matic drive fluid was only available at GM dealerships. As a result, regular SAE 20 engine oil was being used in its place at filling stations and repair garages. Engine oil was only approved as a temporary fill fluid and led to transmission problems. In 1949, General Motors (GM) established an Automatic Transmission Fluid (ATF) Committee (GM ATF Committee). The GM ATF committee established fluid specifications and
2072-500: The Type "A" fluids produced from 1949 to 1966. This fluid was first used in the following transmissions: The original DEXRON (B) fluid, as well as earlier GM transmission fluids, used sperm whale oil as an additive to coat internal transmission parts to prevent corrosion and rust. The U.S. Endangered Species Act banned the import of sperm whale oil, so the DEXRON (B) fluid additive package had to be reformulated. In 1973, GM introduced DEXRON-II(C) (GM Spec GM6032M). DEXRON-II(C)
2146-500: The U.S. government created the Corporate Average Fuel Economy (CAFE) regulations in 1975. The regulations were to be fully implemented by the 1978 model year. The automotive industry responded by changing to three typically unused transmission technologies: The introduction of the TCC led to customer complaints of a shudder while driving. All vehicle manufacturers made changes to their ATF specifications and
2220-577: The VCCC shuddering issue. It is also suitable for power steering systems, some hydraulic systems, and rotary air compressors where excellent low-temperature fluidity is required. GM DEXRON-III (G) licensed products have a license number on the can that begins with the letter G. This fluid is backward compatible with all previous DEXRON fluids as well as the Type "A" suffix "A" and the Type "A" fluids produced from 1949 to 1966. Introduced in 2003, GM's DEXRON III (H) specification (GMN 10055) replaced III (G). The H
2294-471: The ability of a compiler for a newer version of the language to accept source code of programs or data that worked under the previous version. A data format is said to be backward compatible when a newer version of the program can open it without errors just like its predecessor. There are several incentives for a company to implement backward compatibility. Backward compatibility can be used to preserve older software that would have otherwise been lost when
MERCON - Misplaced Pages Continue
2368-527: The aluminum beaker oxidation test (ABOT) to replace the older Merc-O-Matic oxidation test. The Ford Type-H fluid was compatible with GM Dexron II(D) specifications. This compatibility may suggest to some that all Ford, Mercon, and Dexron fluids are compatible; this is not correct. Always use the factory-recommended fluid for your transmission. (See the Aftermarket Automatic Transmission Fluids section below) This fluid
2442-479: The basis that it would allow for easy backwards compatibility with the original Nintendo Entertainment System (NES), but ultimately did not proved to be workable once the rest of the Super NES's architecture was designed. Dexron DEXRON is the trade name for a group of technical specifications for automatic transmission fluid (ATF) created by General Motors (GM). The name was first registered as
2516-635: The cold temperature performance of the ATF flowing through solenoids. In 1990, DEXRON-II (E) (GM Spec GM6137M) was released. DEXRON-II (E) was composed of Group 2 base oil plus an additive package. According to the GM Technical Service Bulletin 92-7-2 issued on October 2, 1991, DEXRON-II(E) has better anti-foaming characteristics, improved low-temperature flow characteristics (low-temperature viscosity), and improved high-temperature oxidation stability. This fluid's low-temperature performance
2590-666: The controls of their TCC to try and alleviate the problem. GM released the Dexron-II (D) fluid specification in 1978 and Chrysler released the ATF+2 fluid specification in 1980, and Ford released the Type-H fluid (M2C166-H) specification in June 1981. The Type-H fluid specification provided improved friction characteristics in lock-up torque converters (reducing shudder during application and release). With this new specification, Ford introduced
2664-480: The controls of their TCC to try to alleviate the problem. GM released a revision to the DEXRON-II(D) fluid specification in 1978, Chrysler released the ATF+2 fluid specification (MS-7176D) in 1980, and Ford released the Mercon Type "H' fluid specification (M2C166-H) in 1981. This fluid was first used in the following transmissions: The equivalent on ELF is RenaultMatic D2. In the 1990s, electronic controls of
2738-551: The crankshaft and tricking the ECM into thinking there was a cylinder misfire. The solution was to create a new kind of TCC that would normally slip around 35 rpm. GM called it the Variable Capacity Converter Clutch (VCCC); other manufacturers had their own names. Some VCCC systems had a shudder or vibration during normal operation. Engineers tried several computer calibration changes, but a revised fluid
2812-520: The details below for the backward compatibility of each fluid. The automatic safety transmission was first offered as an extra-cost option by the Oldsmobile Division of GM in the fall of 1937 for their Six and Eight models. It was only used during the 1938 and 1939 model years. The automatic safety transmission used the same seasonal grade of motor oil as the engine for lubrication and hydraulic functions. The Automatic Safety Transmission
2886-513: The first Intel 8086 / 8088 processors in 1978, again with migrations over the decades from 16-bit to 64-bit. (The 8086/8088, in turn, were designed with easy machine-translatability of programs written for its predecessor in mind, although they were not instruction-set compatible with the 8-bit Intel 8080 processor of 1974. The Zilog Z80 , however, was fully backward compatible with the Intel 8080.) Fully backward compatible processors can process
2960-446: The fluid container. As a result, qualified GM automatic transmission fluid was made available at retailers and service garages in many places. From 1949 to 1951, there were only two licensed fluids: This was the first GM automatic transmission fluid that was made available for sale at retailers other than GM dealerships. In 1951, GM began licensing more Type "A" fluids, which led to several hundred brands of licensed Type "A" fluid on
3034-468: The fluid was measured by a new Merc-O-Matic oxidation test. This fluid was first used in the following transmissions: In 1967, Ford introduced a new fluid specification, the Type-F fluid (M2C33-F). This fluid provided a high static coefficient of friction which resulted in harsh shifting. The Type-F fluid specification was intended to produce a “lifetime” fluid that would never need to be changed. This
MERCON - Misplaced Pages Continue
3108-513: The following transmissions: In September 1974, Ford introduced a new fluid specification, the Type-CJ fluid (M2C138-CJ). This fluid provided smoother shifting and less gear noise by with higher dynamic friction characteristics. The Ford Type-CJ fluid specification also met the GM Dexron -II(D) and earlier fluid specifications. Ford was a licensed GM Dexron-II(D) vendor. The Ford Type-CJ fluid
3182-664: The main CPU for PS1 mode or upclocking itself to offload I/O in PS2 mode. This coprocessor was replaced with a PowerPC -based processor in later systems to serve the same functions, emulating the PS1 CPU core. Such an approach can backfire, though, as was the case of the Super Nintendo Entertainment System (Super NES). It opted for the more peculiar 65C816 CPU over the more popular 16-bit microprocessors on
3256-561: The market. This fluid is backward compatible with the Hydra-Matic Drive fluid produced from 1940 to 1949. It is important to understand that every automatic transmission produced by any vehicle manufacturer (Oldsmobile, Cadillac, Buick, Chevrolet, Pontiac, GMC, Ford, Mercury, Lincoln, Chrysler, Dodge, Desoto, Packard, and Studebaker) used motor oil or the GM Type "A" transmission fluids from 1949 to 1958. In 1950, Ford released their 1951 Fordomatic 3-speed transmission, which used
3330-448: The new fluid hygroscopic , which, while it was not a major problem in automatic transmissions, made DEXRON-II(D) unsuitable for other hydraulic systems in which it was commonly used. GM DEXRON-II(D) licensed products have a license number on the container that begins with the letter D. This fluid is backward compatible with all previous DEXRON fluids as well as the Type "A" Suffix "A", and the Type "A" fluids produced from 1949 to 1966. As
3404-431: The new system. Because of this, several console manufacturers phased out backward compatibility towards the end of the console generation in order to reduce cost and briefly reinvigorate sales before the arrival of newer hardware. It is possible to bypass some of these hardware costs. For instance, earlier PlayStation 2 (PS2) systems used the core of the original PlayStation (PS1) CPU as a dual-purpose processor, either as
3478-492: The newest generation of consoles such as PlayStation 5 and Xbox Series X/S also support this feature. A large part of the success and implementation of this feature is that the hardware within newer generation consoles is both powerful and similar enough to legacy systems that older titles can be broken down and re-configured to run on the Xbox One. This program has proven incredibly popular with Xbox players and goes against
3552-497: The original PlayStation (PS) software discs and peripherals is considered to have been a key selling point for the PlayStation 2 (PS2) during its early months on the market. Despite not being included at launch, Microsoft slowly incorporated backward compatibility for select titles on the Xbox One several years into its product life cycle. Players have racked up over a billion hours with backward-compatible games on Xbox, and
3626-467: The previous specification, transmission fluid service life was fairly short, and frequent transmission oil changes were required. In 1960, Ford introduced the Type-D (M2C33-D) specification for service fluid use in 1960 model-year vehicles. This fluid specification change provided better oxidation control, anti-wear performance, and higher static capacity capabilities were also included. Oxidation control of
3700-424: The previously accepted practice of using SAE 20 engine oil. This fluid was composed of a Group 1 base oil and additives to reduce oxidation, foaming, rust, corrosion, varnish, and sludge buildup. This was the world's first automatic transmission fluid, designed for the world's first mass-produced automatic transmission. This fluid had cold-weather performance problems, which led to the need for an improved fluid,
3774-423: The product that may lead to longer time to market , technological hindrances, and slowing innovation; and increased expectations from users in terms of compatibility. It also introduces the risk that developers will favor developing games that are compatible with both the old and new systems, since this gives them a larger base of potential buyers, resulting in a dearth of software which uses the advanced features of
SECTION 50
#17328012285913848-424: The recent trend of studio-made remasters of classic titles, creating what some believe to be an important shift in console makers' strategies. The monetary costs of supporting old software is considered a large drawback to the usage of backward compatibility. The associated costs of backward compatibility are a larger bill of materials if hardware is required to support the legacy systems; increased complexity of
3922-494: The same binary executable software instructions as their predecessors, allowing the use of a newer processor without having to acquire new applications or operating systems . Similarly, the success of the Wi-Fi digital communication standard is attributed to its broad forward and backward compatibility; it became more popular than other standards that were not backward compatible. In software development, backward compatibility
3996-441: The same low-temperature fluidity as Dexron-II (E), for better transmission performance in cold weather. This specification failed to address a number of issues concerning long-term durability, such as shear stability and fluid oxidation. DEXRON-III (F) underwent a number of iterations in an attempt to address various shortcomings but was eventually replaced by new thinking, i.e., DEXRON-VI (J). GM DEXRON-III (F) licensed products have
4070-444: The sum signal while ignoring the difference signal, which is necessary only for separating the audio channels. Stereo FM receivers can receive a mono signal and decode it without the need for a second signal, and they can separate a sum signal to left and right channels if both sum and difference signals are received. Without the requirement for backward compatibility, a simpler method could have been chosen. Full backward compatibility
4144-456: The transmission fluid specification was co-developed by Ford and GM. The current specification that defines the fluid is FORD WSS-M2C949-A. This fluid is also marketed as Dexron ULV. NOTICE: The quart containers of Mercon ULV must be shaken to stir up the additives before pouring. This fluid is not backward compatible with any previous fluids. This fluid was first used in the following transmissions: The 1967 Ford Type-F fluid specification
4218-437: The transmission phased out the old hydraulic/mechanically controlled system. GM was first to market with Cadillac Allante's electronic-controlled transmission system, THM F-7, in 1987, followed by Chrysler and Toyota in 1988, and Ford in 1989. Electronic control of shift pattern (when it shifts), shift timing (how long it takes to shift), shift quality (shift feel), line pressure, and TCC apply and release rates were all affected by
4292-476: The transmission would start in 1st gear, jump to 3rd, then shift to 4th gear. The driver could change ranges with a flick of a finger. Released in 1939, the 1940–1949 GM Hydra-Matic Drive was used by the Oldsmobile , Cadillac , and Pontiac divisions. The Hydra-Matic Drive used a specialized lubricant called GM Transmission Fluid No. 1. By using the term "fluid" rather than "oil," they hoped to discourage
4366-527: The world; many of these may use their own unique fluid. Originally, the DEXRON name was only associated with automatic transmission fluids, though GM later released DEXRON gear oils and other lubricants under the DEXRON brand. The original DEXRON (B) transmission fluid was introduced on April 1, 1967. Over the years, the original DEXRON (B) was supplanted by DEXRON-II (C), DEXRON-II (D), DEXRON-II (E), DEXRON-III (F), DEXRON-III (G), DEXRON-III (H), DEXRON-VI (J), DEXRON HP, DEXRON LV ATF HP, and DEXRON ULV, which
4440-561: Was a four-speed transmission that could shift powerfully without needing a regular clutch. The transmission was called the Automatic Safety Transmission (AST) because the clutch operation was reduced to one-third of that required by a conventional transmission. The clutch was only necessary when starting or stopping the car. The AST had two driving ranges (low and high). In low range, the transmission would shift from 1st to 2nd gear and then hold in 2nd. In high range,
4514-424: Was also improved (20,000 cP at -40 °C vs. 50,000 cP at -40 °C). GM DEXRON-II (E) licensed products have a license number on the container that begins with the letter E. This fluid is backward compatible with all previous DEXRON fluids as well as the Type "A" suffix "A" and the Type "A" fluids produced from 1949 to 1966. This fluid was first used in the following transmissions: The DEXRON-II (E) fluid specification
SECTION 60
#17328012285914588-577: Was also needed to address the issue. Ford released the new Mercon V Fluid Specification in 1996; GM released the DEXRON-III (G) Fluid Specification (GM6417M) in 1998; and Chrysler released the MS-9602 Change C Fluid Specification in 1999. This fluid was first used in the following transmissions: Released in December 1998, GM's DEXRON-III (G) specification (GM6417M) was a synthetic blend automatic transmission fluid, specially developed to address
4662-423: Was compatible with GM Dexron II(D) specifications. This compatibility may suggest to some that all Ford, Mercon, and Dexron fluids are compatible; this is not correct. Always use the factory-recommended fluid for your transmission. (See the Aftermarket Automatic Transmission Fluids section below) This fluid was first used in the following transmissions: As a result of the 1973 OPEC Oil Embargo and fuel shortages,
4736-492: Was compatible with GM's Dexron-II(D) and later formulations were compatible with Dexron-III(H); however, Future versions of Mercon (Mercon V, Mercon SP, Mercon LV, Mercon ULV) are not compatible with GM's Dexron-III(H) or any newer version of Dexron (Dexron-VI, Dexron HP, Dexron ULV). This fluid was first used in the following transmissions: In 1996, Ford released the Mercon "V" fluid specification (M2C202-B). Ford Technical Service Bulletin (TSB) 06-14-04 indicates that Mercon "V"
4810-463: Was composed of a more stable, less reactive, hydrocracked Group 2 base oil plus a revised additive package with corrosion and rust inhibitors such as jojoba oil ; however, the additive package caused problems with corrosion-prone solder in a relatively small number of GM's transmission fluid coolers. After discovering the corrosion problem, GM updated the fluid specification again and released DEXRON-II(D) in 1975. GM DEXRON-II(C) licensed products have
4884-420: Was first used in the following transmissions: In January 1987, Ford released the original Mercon fluid specification (M2C185-A). Mercon became a trademarked fluid with the qualification and licensing of fluids to ensure quality in the marketplace. This original Mercon Specification was backward compatible with the 1981 Ford Type-H fluid and the 1958 GM Type "A" Suffix "A" fluid. NOTICE: This version of Mercon
4958-791: Was intended to produce a “lifetime” fluid which would never need to be changed. This was the first of many Ford “lifetime” fluids. The 1974 Ford Car Shop Manual reads "The automatic transmission is filled at the factory with "lifetime" fluid. If it is necessary to add or replace fluid, use only fluids which meet Ford Specification M2C33F. Many other transmission manufacturers have followed with their own "Lifetime" automatic transmission fluids". Lifetime automatic transmission fluids made from higher quality base oil and an additive package are more chemically stabile, less reactive, and do not experience oxidation as easily as lower quality fluids made from lower quality base oil and an additive package. Therefore, higher quality transmission fluids can last
5032-563: Was introduced in January 1987. Over the years, the original Mercon was supplanted by Mercon "V", Mercon "SP", Mercon LV, and Mercon ULV, which is the latest automatic transmission fluid. Ford has upgraded the Mercon specifications over the years; the newer fluids are not always backward compatible with previous fluids. Newer 6 and 10-speed transmissions as well as Plug-In Hybrid (PHEV), and Electric Vehicle (EV) transmission technologies require specialized fluids to operate properly. There remains
5106-742: Was marketed under the Ford brand name.
