An automatic transmission sometimes abbreviated to auto or AT is a multi-speed transmission used in motor vehicles that does not require any driver input to change gears under 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. The Sturtevant "horseless carriage gearbox" is often considered to be the first automatic transmission.

How It Works: Automatic transmissions

According to Meineke, most automobiles use a form of automatic transmission called a hydraulic planetary automatic transmission, which is also used in a scaled-up version in some industrial and commercial equipment and heavy-duty vehicles. The friction clutch is replaced by fluid coupling and the system defines a set of gear ranges depending on the needs of the auto. When you put the vehicle in park, all the gears lock to prevent the car from rolling forward or backward.

Automatic Transmission AT. Manual Transmission MT. The driver selects all gears manually using both a movable gear selector and a driver-operated clutch. Automated Manual Transmission AM. The basic components of a transmission are:. Planetary gear sets.

Automatic transmissions are operated by hydraulics as well as electronics to select according to engine speed, powertrain load, vehicle speed, and other factors. The number of forward gears offered in current vehicle ranges from to and there are also continuously variable designs CVT with no fixed ratio. All offer at least one overdrive ratio for mpg. Drive Driven Neutral.
