A vehicle transmission controller controls switching of the gear position of a transmission. The controller has a shift lever and an actuator. The shift lever is manipulated to select a gear position of the transmission. The actuator actuates the transmission to switch the gear position in accordance with a manipulation of the manipulator. The actuator switches the transmission to the gear position selected by the manipulator. The actuator switches the transmission to a predetermined gear position from the gear position selected by the manipulator when the vehicle satisfies predetermined conditions.
