ABSTRACT:
An electric shift apparatus for use with a motor vehicle having an automatic transmission. The apparatus includes a power module adapted to be mounted on the housing of the transmission proximate the transmission mode select lever and the transmission kick-down lever and a control module adapted to be mounted in the passenger compartment of the vehicle. The power module includes an electric motor assembly drivingly connected to the free end of the mode select lever and a solenoid drivingly connected to the free end of the kick-down lever. The control module includes a plurality of push button members corresponding respectively to the transmission shift positions. An encoder device carried by the motor assembly of the power module provides a constant coded signal indicating the instantaneous position of the transmission mode select lever and this coded signal is compared by comparator means in the logic of the control unit with the selected shift position. The comparator means generates a signal to the motor assembly to move the mode select lever in a direction to achieve the selected shift position and stops the motor assembly when the encoder signal received from the power module matches the selected shift position indicating that the selected shift position has been achieved.
