Abstract

This disclosure relates to an automatic transmission, and more particularly, to an automatic transmission which alleviates a gear shifting shock generated during a forward/reverse gear shifting operation by controlling a clutch actuator to operate a clutch and interrupting a transmission of power generated from an engine during the forward/reverse gear shifting operation of a vehicle. Provided is an automatic transmission for changing a direction of rotation power generated from an engine so as to change a vehicle moving direction, the automatic transmission including: a first gear which changes the direction of the rotation power generated from the engine to a vehicle forward direction; a second gear which changes the direction of the rotation power generated from the engine to a vehicle reverse direction; a forward/reverse lever which inputs a start signal for changing the direction of the rotation power generated from the engine; a clutch actuator which drives a clutch for selectively interrupting a transmission of the power generated from the engine; a forward/reverse actuator which rotates a rotation shaft extending from the forward/reverse lever; a synchromesh which changes its position so as to mesh with the first or second gear in accordance with a driving operation of the forward/reverse actuator; and a controller which generates a control signal for driving the clutch actuator upon receiving the start signal from the forward/reverse lever and controls the driving operation of the forward/reverse actuator.
