List Of GM Transmissions
General Motors (GM) is an American car designing and manufacturing company. It manufactures its own automobile transmissions and only occasionally purchases transmissions from outside suppliers as needed. GM transmissions are used in passenger cars and SUVs, or in light commercial vehicles such as vans and light trucks. While there is much variation within each type, in a very general sense there are two types of motor vehicle transmissions: * Manual – The driver performs each gear change by operating a gear shift lever combined with a manually operated clutch. * Automatic – Once the driver place a gear range selector in its automatic position, usually "Drive" or "D," the transmission selects gear ratios based on many factors, including engine speed, vehicle speed, engine load, accelerator position, gear range selector position, road incline/decline, and more. For the purposes of this article, there are two primary types of engine orientation: * Longitudinal – T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Transaxle
A transaxle is single mechanical device which combines the functions of an automobile's transmission (mechanics), transmission, axle, and differential (mechanics), differential into one integrated assembly. It can be produced in both manual transmission, manual and automatic transmission, automatic versions. Engine and drive at the same end Transaxles are nearly universal in all automobile configurations that have the engine placed at the same end of the car as the driven wheels: the front-engine, front-wheel-drive layout, front-engine/front-wheel-drive; rear-engine, rear-wheel-drive layout, rear-engine/rear-wheel-drive; and rear mid-engine, rear-wheel-drive layout, mid-engine/rear-wheel-drive arrangements. Many mid-engine design, mid- and rear-engine design, rear-engined vehicles use a transverse engine and transaxle, similar to a front-wheel-drive unit. Others use a longitudinal engine and transaxle like Ferrari's 1989 Ferrari Mondial#Mondial t, Mondial t which used a "T" ar ...

Continuously Variable Transmission
A continuously variable transmission (CVT) is an automated Transmission (mechanical device), transmission that can change through a continuous range of gear ratios, typically resulting in better fuel economy in gasoline applications. This contrasts with other 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 a constant angular velocity while the vehicle moves at varying speeds. Thus, CVT has a simpler structure, longer internal component lifespan, and greater durability. Compared to traditional automatic transmissions, it offers lower fuel consumption and is more environmentally friendly. CVTs are used in cars, tractors, Side-by-side (vehicle), side-by-sides, motor scooters, snowmobiles, bicycles, and Heavy equipment, earthmoving equipment. The most common type of CVT uses two pulleys connected by a Belt (mechanical), belt or Chain drive, chain; however, several other desig ...

Turbo-Hydramatic
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-Mat ...

Powerglide
The Powerglide is a two-speed automatic transmission designed by General Motors. It was available primarily on Chevrolet from January 1950 through 1973, although some Pontiac models also used this automatic transmission after the fire at the Hydra-Matic factory in 1953. Powerglides were used extensively on Pontiacs produced for the Canadian market with Chevrolet powertrains. They were also used with Nova engines in the DJ-5A Jeeps produced 1968-1970 by Kaiser-Jeep and widely used as delivery vehicles by the United States Post Office. When introduced on upper-level Chevrolet models in 1950, the Powerglide represented the first automatic transmission offered in a low-priced automobile; in contrast, Ford did not offer their automatic transmission until 1951, while Plymouth car buyers had to wait until 1954. The transmission was simple and very durable, which satisfied customers. History The 1950 through 1952 Powerglide transmissions did not automatically shift between low and ...
