ABSTRACT:
An operating position select device has a select lever unit, a mode shift unit to shift operation modes of the automatic transmission, a mechanically connecting means connecting them, and an assist actuator to assist a select lever. A control unit that controls the actuator is electrically connected to an operating position sensor detecting an operating position of the select lever and an operating force sensor detecting operating force acting on the lever. The control unit has an improper halt detecting part detecting the improper halt of the lever between the select positions and an improper halt preventing part preventing the lever from being kept halted improperly between the select positions to provide the lever with adjustment force so that the lever moves to one of the select positions when the improper halt of the select lever is detected during select operation.
