ABSTRACT:
A controller determines the state of the range detector on the basis of the detection signals detected by the range detector, then when the range detector is determined to be in an abnormal condition, the controller moves the shift-changing valve until the movement is inhibited by the restriction member, thereby establishes the position of one end, and controls the actuator with respect to the established one end position and on the basis of the amount of operation to move the shift-changing valve to the position corresponding to an instructed shift range. Even when the range detector is in an abnormal condition, it is possible to make a change to the shift range corresponding to a shift range changing command.
