A vehicular transmission comprises an electrical control unit ECU, which controls to bring a starting clutch into loose engagement for a predetermined time while a deactivated cylinder mode is being terminated. The electrical control unit also estimates, during this predetermined time, an estimated PB, which is an estimated pressure inside the intake pipe, on the basis of a rotational speed Ne at the output shaft of the engine and of an opening TH at the throttle valve, and it then estimates or calculates the driving torque generated by the engine on the basis of this estimated PB and the rotational speed Ne. From this calculated driving torque, the electrical control unit sets respective pressures to be applied to a drive pulley and a driven pulley, which constitute a continuously variable transmission CVT.
