The automatic transmission works by using a fluid coupling in place of a friction clutch. It drives the gear alterations by hydraulically locking and unlocking the planetary gears.
An average vehicle transmission is made of 3 to six equipment sets, as well as a number of equipment trains. These equipment trains are basically belts or chains that run alongside the outside of two or even more gears, making it possible for the driving force to control the power supply to the vehicle.
