automatic transmission
No clutch pedal
An automatic transmission is a vehicle gearbox that shifts gears without driver input, using a torque converter and hydraulic system to match engine speed to road conditions.
Most American cars have had automatic transmissions since the mid-20th century: I never learned to drive stick—all our cars were automatics.
Often shortened to automatic.
Contrast with manual transmission.
