ABSTRACT:
An electronic/electromechanical transmission shifter has a velocity detector which generates an electrical signal representing the vehicle velocity. A microcomputer is connected to the velocity detector, to a plurality of manually controlled switches and to a digitally controlled linear actuator which is linked to the shift member of the vehicle. The shifter position is detected by a cam mounted on the screw shaft of the linear alternator operating against a plurality of microswitches which are mounted about and axially spaced along the screw shaft. The cam follower portions of the microswitches are engagable with the cam to indicate shifter position.
