WHAT IS AUTOMATICALLY TRANSMISSION
Answers
Explanation:
An automatic transmission is multi-speed transmission used in motor vehicles that does not require any driver input to change gears in normal driving conditions. The most common type of automatic transmission is the hydraulic automatic, which uses a planetary gearset, hydraulic controls and a torque convertor.
An automatic transmission (sometimes abbreviated to auto or AT) is multi-speed transmission used in motor vehicles that does not require any driver input to change gears in normal driving conditions.
The most common type of automatic transmission is the hydraulic automatic, which uses a planetary gearset, hydraulic controls and a torque convertor. Other types of automatic transmissions include continuously variable transmissions (CVT), automated manual transmissions (AMT), and dual-clutch transmissions (DCT).
The 1904 Sturtevant "horseless carriage gearbox" is often considered to be the first automatic transmission. The first mass-produced automatic transmission is the General Motors Hydramatic three-speed hydraulic automatic (using a fluid coupling instead of a torque convertor), which was introduced in 1939.
