List Of GM Transmissions
General Motors is an innovator of automatic transmissions, introducing the Hydra-Matic in 1940. This list includes some GM transmissions. Automatic transmissions Early models The GM Hydra-Matic was a success and installed in the majority of GM models by 1950. Through the 1950s, all makers were working on their own automatic transmission, with four more developed inside GM alone. All of GM's early automatic transmissions were replaced by variants of the Turbo-Hydramatic by the 1970s. *1940–1967 Hydra-Matic — Oldsmobile (now the trade name for all GM automatic transmissions) *1948–1963 Dynaflow — Buick *1950–1973 Powerglide — Chevrolet (also used by Pontiac, Holden, Vauxhall and Opel) *1968-1971 Torquedrive- Chevrolet ( Camaro and Chevy II, Nova.

TH400
Turbo-Hydramatic or Turbo Hydra-Matic is the registered tradename for a family of automatic transmissions developed and produced by General Motors. These transmissions mate a three-element turbine torque converter to a Simpson planetary geartrain, providing three forward speeds plus reverse. The Turbo-Hydramatic or Turbo Hydra-Matic (THM) series was developed to replace both the original Hydra-Matic models and the Buick Dynaflow. In its original incarnation as the Turbo-Hydramatic 400, it was first used in the 1964 model year in Cadillacs. The Buick version, which followed shortly thereafter, was known as the Super-Turbine 400. By 1973, THM units had replaced all of GM's other automatic transmissions including Chevrolet's Powerglide, Buick's Super Turbine 300, and Oldsmobile's Jetaway. Starting in the early 1980s, the Turbo-Hydramatic was gradually supplanted by four-speed automatics, some of which continue to use the "Hydramatic" trade name. Although the Turbo Hydra-Matic n ...

Chevrolet Chevy II / Nova
The Chevrolet Chevy II/Nova is a small automobile manufactured by Chevrolet, and produced in five generations for the 1962 through 1979, and 1985 through 1988 model years. Nova was the top model in the Chevy II lineup through 1968. The Chevy II nameplate was dropped after 1968, with Nova becoming the nameplate for all of the 1969 through 1979 models. Built on the X-body platform, the Nova was replaced by the 1980 Chevrolet Citation introduced in the spring of 1979. The Nova nameplate returned in 1985, produced through 1988 as a S-car based, NUMMI manufactured, subcompact based on the front wheel drive, Japan home-based Toyota Sprinter. History Origin Chevrolet designer Clare MacKichan recalled about creating the Chevy II: "There was no time for experimentation or doodling around with new ideas from either the engineers or from us in design; And it had to be a basic-type car." The 1962 Chevy II rode a wheelbase, compared to for the Ford Falcon, at which Chevy's new compac ...

Turbo-Hydramatic 180
Holden, formerly known as General Motors-Holden, was an Australian subsidiary company of General Motors. It was an Australian automobile manufacturer, importer, and exporter which sold cars under its own marque in Australia. In its last three years, it switched entirely to importing cars. It was headquartered in Port Melbourne, with major industrial operations in the states of South Australia and Victoria. The 164-year-old company ceased trading at the end of 2020. Holden's primary products were its own models developed in-house, such as the Holden Commodore, Holden Caprice, and the Holden Ute. However, Holden had also offered badge-engineered models under sharing arrangements with Chevrolet, Isuzu, Nissan, Opel, Suzuki, Toyota, and Vauxhall Motors. The vehicle lineup had included models from GM Korea, GM Thailand, GM North America. Holden had also distributed GM's German Opel marque in Australia in 2012 and 2013. Holden was founded in 1856 as a saddlery manufacturer ...

Turbo-Hydramatic 425
Turbo-Hydramatic 425 (TH425 or THM 425, later 325) was an automatic transmission developed and produced by General Motors. The THM425 was a derivative of the THM400; most parts directly interchange and some others will interchange with minor modifications. The internal parts spin the opposite direction in the THM425; the helical angle of the planetary gears is "reversed" and the one-way clutches freewheel in the opposite direction, for example. The THM425 was developed for the 1966 Oldsmobile Toronado and the 1967 Cadillac Eldorado. A lighter-duty transmission known as the THM325 (using components sourced from the THM200) replaced the THM425 in both car lines after the 1978 model year. 1979 and later longitudinal engine front-wheel drive vehicles used the THM325. The THM325 became the THM325-4L with an overdrive added in 1982, but all vehicles using this transmission switched to more-conventional transverse engine mounting in 1986. Bellhousing pattern used the 1967-90 Buick-Oldsmo ...

Longitudinal Engine
In automotive engineering, a longitudinal engine is an internal combustion engine in which the crankshaft is oriented along the long axis of the vehicle, front to back. Use This type of motor is usually used for rear-wheel drive cars, except for some Audi and SAAB models equipped with longitudinal engines in front wheel drive. In front-wheel drive cars a transverse engine is usually used. Trucks often have longitudinal engines with rear-wheel drive. For motorcycles, the use of a particular type depends on the drive: in case of a chain or belt drive a transverse engine is usually used, and with shaft drives a longitudinal engine. Longitudinal engines in motorcycles do have one disadvantage: the "tipping point" of the crankshaft tilts along the entire motorcycle to a greater or lesser degree when accelerating. This is partly resolved by having other components, such as the generator and the gearbox, rotate in the opposite direction to the crankshaft. Most larger, "premium" ve ...

Transverse Engine
A transverse engine is an engine mounted in a vehicle so that the engine's crankshaft axis is perpendicular to the direction of travel. Many modern front-wheel drive vehicles use this engine mounting configuration. Most rear-wheel drive vehicles use a longitudinal engine configuration, where the engine's crankshaft axis is parallel with the direction of travel, except for some Mid-engine design, rear-mid engine vehicles, which use a transverse engine and transaxle mounted in the rear instead of the front. Despite typically being used in light vehicles, it is not restricted to such designs and has also been used on Armoured fighting vehicle, armoured fighting vehicles to save interior space. History The Critchley Light car, Critchley light car, made by the Daimler Company, Daimler Motor Company in 1899, had a transverse engine with belt drive to the rear axle. The first successful transverse-engine cars were the two-cylinder DKW F1 series of cars, which first appeared in 1931. Du ...

Front-wheel Drive
Front-wheel drive (FWD) is a form of engine and transmission layout used in motor vehicles, where the engine drives the front wheels only. Most modern front-wheel drive vehicles feature a transverse engine, rather than the conventional longitudinal engine arrangement generally found in rear-wheel drive and four-wheel drive vehicles. Location of engine and transmission By far the most common layout for a front-wheel drive car is with the engine and transmission at the front of the car, mounted transversely. Other layouts of front-wheel drive that have been occasionally produced are a front-engine mounted longitudinally, a mid-engine layout and a rear-engine layout. History Prior to 1900 Experiments with front-wheel drive cars date to the early days of the automobile. The world's first self-propelled vehicle, Nicolas-Joseph Cugnot's 1769/1770 "fardier à vapeur", was a front-wheel driven three-wheeled steam-tractor. It then took at least a century, for the first e ...

Rear-wheel Drive
Rear-wheel drive (RWD) is a form of engine and transmission layout used in motor vehicles, in which the engine drives the rear wheels only. Until the late 20th century, rear-wheel drive was the most common configuration for cars. Most rear-wheel drive vehicles feature a longitudinally-mounted engine at the front of the car. Layout The most common layout for a rear-wheel drive car is with the engine and transmission at the front of the car, mounted longitudinally. Other layouts of rear-wheel drive cars include front-mid engine, rear-mid engine, and rear-engine. Some manufacturers, such as Alfa Romeo, Lancia, Porsche (944, 924, 928) and Chevrolet (C5, C6, and C7 Corvettes), place the engine at the front of the car and the transmission at the rear of the car, in order to provide a more balanced weight distribution. This configuration is often referred to as a transaxle since the transmission and axle are one unit. History 1890s to 1960s Many of the cars built in the 19t ...

Hydramatic
Hydramatic (also known as Hydra-Matic) is an automatic transmission developed by both General Motors' Cadillac and Oldsmobile divisions. Introduced in 1939 for the 1940 model year vehicles, the ''Hydramatic'' was the first mass-produced fully-automatic transmission developed for passenger automobile use. History During the 1930s, automakers sought to reduce or eliminate the need to shift gears. At the time, synchronized gear shifting was still a novelty (and confined to higher gears in most cases), and shifting a manual gearbox required more effort than most drivers cared to exert. The exception here was Cadillac's break-through synchromesh fully synchronized manual transmission, designed by Cadillac engineer Earl A. Thompson and introduced in the fall of 1928. Cadillac, under Thompson, began working on a 'shiftless' transmission in 1932, and a new department within Cadillac Engineering was created, headed by Thompson and including engineers Ernest Seaholm, Ed Cole, Owen Nack ...
