    摘要： A control system for an automatic transmission, comprising: a fluid transmission unit for transmitting the rotation of an engine to a speed change unit; a clutch adapted to be applied when a forward running range is selected, to transmit the rotation of the fluid transmission unit to the transmission mechanism of the speed change unit; stop state detecting means for detecting stop state of a vehicle, in which a forward running range is selected, in which the throttle opening is fully closed, in which the brake pedal is depressed and in which the vehicle speed is substantially zero; engine RPM detecting means for detecting the engine RPM; application force generating means for generating the application force of the clutch; and a control unit. The control unit releases the clutch by weakening the application force of the clutch when the stop state of the vehicle is detected by the stop state detecting means. The engine RPM when the clutch is released is stored as an initial engine RPM in storage means so that an end engine RPM is set on the basis of the initial engine RPM. The clutch is applied by strengthening its application force if the stop state of the vehicle is not detected when the clutch is released and if the engine RPM exceeds the end engine RPM.
