A transmission controller increases hydraulic pressure supplied to a secondary pulley and decreases hydraulic pressure supplied to a primary pulley to shift a variator to a mechanical Low speed ratio during the hydraulic pressure supplied to the primary pulley and the secondary pulley vibrates. The mechanical Low speed ratio is a speed ratio where a groove width of the primary pulley has a maximum value possible to be employed in structure of the primary pulley.
