A transmission for a vehicle is provided which prevents generation of a speed change shock at the time of starting the vehicle from a neutral condition. In the transmission, hydraulic clutches are each put into a connected state according to an action of an oil pressure, and a plurality of selectively engageable speed-stage gear trains are provided so that a neutral condition can be obtained. At the time of shifting from the neutral condition, where the oil pressures in hydraulic clutches are in a lowered state, to a starting condition in which a starting gear train is engaged, pressure in the hydraulic clutch corresponding to the starting gear train is controlled by a control valve, so that the oil pressure in the hydraulic clutch is maintained in the lowered state during and immediately after a shifting operation, and is subsequently increased in response to complete engagement of the starting gear train.
