Which Car Has the First Automatic Transmission?
The First Automatic Transmission
The first automatic transmission was invented by Alfred Horner Munro in 1921. It was a two-speed transmission that was installed in a Cadillac V8. This transmission used a planetary gearset to automatically shift gears, and it was controlled by a governor that sensed the speed of the engine and the car.
The Chrysler Fluid Drive
In 1939, Chrysler introduced the Fluid Drive transmission. This transmission was a three-speed transmission that used a fluid coupling to automatically shift gears. The fluid coupling was a device that used fluid to transmit power from the engine to the transmission, and it allowed the transmission to shift gears smoothly and without any jerking.
The General Motors Hydra-Matic
In 1940, General Motors introduced the Hydra-Matic transmission. This transmission was a four-speed transmission that was the first automatic transmission to be mass-produced. The Hydra-Matic transmission used a planetary gearset to automatically shift gears, and it was controlled by a governor that sensed the speed of the engine and the car.
The Borg-Warner Automatic Transmission
In 1950, Borg-Warner introduced the first automatic transmission that was designed for use in a compact car. This transmission was a two-speed transmission that was installed in the Studebaker Commander. The Borg-Warner transmission used a planetary gearset to automatically shift gears, and it was controlled by a governor that sensed the speed of the engine and the car.
The Automatic Transmission Today
Today, automatic transmissions are the most common type of transmission used in cars. Automatic transmissions are easy to use and they provide a smooth and comfortable ride. Automatic transmissions are also more fuel-efficient than manual transmissions.
Conclusion
The first automatic transmission was invented by Alfred Horner Munro in 1921. Since then, automatic transmissions have undergone many improvements, and they are now the most common type of transmission used in cars.
