Abstract
A control device for a transmission is used in a transmission that is provided with a continuously variable transmission mechanism including a primary pulley to which a drive force of a drive source mounted on a vehicle is input, a secondary pulley that transmits the drive force of the drive source to a drive wheel, and an endless annular member that is wound around the primary pulley and the secondary pulley. The control device includes a controller configured to perform a gear shift control of changing a transmission gear ratio of the continuously variable transmission mechanism to a high side when rotational oscillation occurs in a rotation member of the continuously variable transmission mechanism and then the rotational oscillation decreases a rotation speed of the rotation member.
