ABSTRACT OF THE DISCLOSURE A control method controls a belt-and-pulley type continuously variable transmission having drive and driven pulleys mounted respectively on input and output shafts, a V-belt trained around the drive and driven pulleys, and an oil pressure source and an oil reservoir operatively coupled to first and second hydraulic pressure chambers for axially moving the movable conical members of the drive and driven pulleys to vary effective diameters of the drive and driven pulleys for thereby controlling a speed ratio. The movable conical members of the drive and driven pulleys are movable in synchronism with each other. The hydraulic pressure chamber of one of the drive and driven pulleys the effective diameter of which is to become larger at that time, is first brought into communication with the oil pressure source. The hydraulic pressure chamber of the other of the drive and driven pulleys the effective diameter of which is to become smaller, is brought into communication with the oil reservoir no earlier than the communication of the hydraulic pressure chamber of the one of the pulleys to the oil pressure source, for thereby starting to move the movable conical members.
