Auto

nounShop talkAutomotive

A transmission that shifts gears on its own without driver input.

An automatic transmission uses a torque converter and planetary gearsets to change ratios based on speed and load. Shop technicians often use this clipped term to distinguish a car's powertrain from a manual gearbox when ordering parts or writing service tickets.
