    摘要： A control system for an automatic transmission, comprising: a clutch adapted to be applied when a forward running range is selected, to transmit the rotation of an engine to the transmission mechanism of a speed change unit; hydraulic servo for applying/releasing the clutch; and a control unit for controlling the oil pressure to be fed to the hydraulic servo. The control unit includes: application starting pressure detecting means for detecting an application starting pressure at the instant when the application of a clutch is started; initial application pressure setting means for setting an initial application pressure on the basis of the application starting pressure which is detected by the application starting pressure detecting means; and oil pressure adjusting means for adjusting the oil pressure to be fed to a hydraulic servo, when a change is made to a forward running range, and then raising the same gradually. The application starting pressure to be detected by the application starting pressure detecting means takes the value at which the application of the clutch is actually started, so that the initial application pressure can be properly set even if the actual oil pressure to be fed to the hydraulic servo is varied by the dispersion in the urging force of a return spring or by the dispersion in a hydraulic control system.
