PROBLEM TO BE SOLVED: To realize desired creep torque reduction by converging slip quantity of torque converters to a set value in an early stage when engine combustion states are changed. SOLUTION: In this control device for an automatic transmission, for reducing creep torque, engagement force is reduced in a clutch 8 to transmit torque from the torque converters 2 and 3 to a gear transmission device 6 to a gear transmission device 6 to slip, and the engagement force of the clutch is feedback-controlled to maintain slip quantity of the torque converters at set quantity. In changing combustion states of an internal combustion engine providing torque to the torque converters, control quantity in feedback-control of the engagement force is changed.
