Automatic Transmission is a transmission that automatically shifts gears with no driver input other than input from the gas pedal. Utilizes a torque converter, planetary gearset, and clutches or bands that automatically change the gears of a vehicle.
- The automatic transmission uses a hydraulic system to shift the gears and transmit power automatically.
- The transmission shifts into higher gears as the car's speed increases and then shifts to lower gears when climbing hills.
- Simply pushing down on the accelerator pedal controls the speed of the vehicle The advantage is easier driving, but with most automatics, there is a loss in fuel economy.
