automatic transmissions
Self-changing gear systems
Automatic transmissions are vehicle gearboxes that shift gears without driver input, using a torque converter or dual-clutch system to match engine speed to driving conditions.
The term distinguishes cars that shift themselves from those requiring a manual clutch and gear lever: I never learned to drive stick—all my cars have had automatic transmissions.
