117. Automatic transmission
An automatic transmission is a vehicle transmission that changes gears automatically without requiring the driver to operate a conventional clutch pedal and manually select each gear. Depending on the design, the driver normally selects positions such as park, reverse, neutral and drive while the transmission manages gear changes.
An automatic transmission can make driving simpler by removing the need to coordinate a clutch pedal and manual gear changes. Automatic transmissions include several different technologies, such as conventional automatics, continuously variable transmissions and dual-clutch systems.

Do all automatic transmissions work in the same way?
No. Automatic transmission controls, operating modes and procedures differ between vehicles. Read the handbook for selecting drive, parking, hill driving and breakdown towing rather than assuming that a familiar selector or procedure works in every model.
