Jul 13, 2021 · Instead of a friction clutch, a hydraulic torque converter is used to swap ratios. Automatic transmissions also entail the use of components such as stators, clutch packs, lockup clutches, bands ...
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 a constant angular velocity while the vehicle moves at varying speeds.
Mar 30, 2021 · 1930’s to 1960’s: 2-Speeds, 3-Speeds & 4-Speeds. In 1939 Cadillac and Oldsmobile became the first manufacturers to utilize a fully automatic transmission in a production vehicle; they named it the Hydra-matic, which would later be named the Turbo Hydra-matic. It was developed for rear-wheel-drive vehicles and had four Forward speeds plus ...
