Abstract

An operating position select device for an automatic transmission has a select lever unit having a select lever operated by a driver; a mode shift unit mounted on the automatic transmission to shift operation modes of the automatic transmission; a first and second control cables and others for mechanically connecting the select lever and the mode shift unit, and an actuator for outputting assist torque to shift the mode shift unit. An operating angle sensor detects an operating angle of the select lever and an assist angle sensor detects an assist angle of the assist actuator. A control unit controls a drive current supplied to the assist actuator based on the operating angle and the assist angle.
