ABSTRACT:
An operating position select device has a select lever unit, a mode shift unit to shift operation modes of the automatic transmission, and an assist actuator controlled by a control unit. A first connecting member of the select lever and a second connecting member of the mode shift unit are relatively movable to a limit amount to each other and integrally movable beyond the limit amount with each other. The positions of the members are detected by an operating position sensor and an assist position sensor, respectively. The actuator is driven so that a difference between an operating position and an assist position may be reduced, but prohibited from driving when the difference is kept out of a permissible range for a predetermined period during rest of the actuator.
