ABSTRACT:
A transmission having an electromechanical gear actuation system includes an input shaft, a counter shaft, and a plurality of gear sets that are adapted to be operatively engaged to and disengaged from their shafts. A plurality of synchronizers operatively engage and disengage the gear sets to and from the shafts. A shifter rail includes a plurality of shift forks that are each in operative engagement with at least one of the synchronizers. A motor assembly provides a first motive force to cause the shifter rail to selectively engage one shift fork and further adapted to provide a second motive force to operatively drive the shifter rail to cause the associated shift fork and synchronizer to engage and disengage the associated gear set to and from the associated shaft. A solenoid assembly controls when the motor assembly provides the first motive force and the second motive force.
