Automated Manual Transmission is an automobile transmission that combines manual transmission and automatic transmission.
It allows convenient driver control of gear selection. For most of automotive history, automatic transmissions already allowed some control of gear selection using the console or shifter, usually to limit the transmission shifting beyond a certain gear (allowing engine braking on downhills) and/or locking out the use of overdrive gears when towing. It enhanced such features by providing either steering wheel mounted paddle shifters or a modified shift lever, allowing the driver to enter a "manual mode" and select any available gear, usually in a sequential "up shift/downshift" manner.
