Automatic Transmissions & Transaxles

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. A less common option is the automated manual transmission AMT.

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.

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. The first mass-produced automatic transmission is the General Motors Hydramatic three-speed hydraulic automatic using a fluid coupling instead of a torque converter , which was introduced in The most common design of automatic transmissions is the hydraulic automatic, which typically uses planetary gearsets that are operated using hydraulics. A hydraulic automatic transmission uses planetary epicyclic gearsets instead of the manual transmission's design of gears lined up along input, output and intermediate shafts.

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.

How Does an Automatic Transmission Work?

An automatic transmission seems pretty simple; after all, you just put it in Drive and go. But as with most things automotive, a lot of complexity goes into making it look easy. The engine contains a heavy central crankshaft cylinder that spins, which provides the power to turn the wheels.
