PURPOSE:To improve the drivability and ride feeling by controlling the transmission torque capacity so that the shock caused by the variation of the transmission torque capacity and the speed change shock are generated at the same time. CONSTITUTION:Hydraulic controllers 9 and 22 are operated on the basis of the control signal supplied from a controller 45, and perform the selection control for the speed change stages of a speed change gear 7 and the engagement- release control of a differential control clutch 21. In this case, the engagement and release of the differential control clutch 21 accompanied with the selection for the speed change stages of the speed change gear 7 are executed synchronously with the selection for the speed change stages of the speed change gear 7 so that the shock due to the variation of the transmission torque capacity of the differential control clutch 21 and the speed change shock are generated at the same time. Therefore, the successive generation of two shocks on the selection of speed change stages is suppressed, and the deterioration of drivability and ride feeling can be avoided.
