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 shaft and a control module adapted to be mounted in the passenger compartment of the vehicle. The power module includes an electric motor driving a speed reduction unit and the lower exposed end of the output shaft of the speed reduction unit is adapted to be drivingly coupled to the exposed upper end of the mode select shaft of the automatic transmission. A manual override is provided so that, in the event of a total loss of vehicle electric power, the transmission may be moved manually to any desired position to facilitate emergency servicing of the vehicle. A pointer mounted on an exposed end of the output shaft of the speed reduction unit coacts with indicia provided on the housing of the speed reduction unit to provide a constant visual indication of the instantaneous position of the transmission to assist in the manual override function.
