ABSTRACT:
The present invention provides a shift mechanism disposed in a housing for providing operable communication between a shift actuator and a shift sleeve. The shift mechanism generally includes a shift rail, a shift fork, a first biasing member, and a second biasing member. The shift rail is slidably supported by the housing. The shift fork is slidably disposed on the shift rail and engages the shift sleeve. The first biasing member is disposed between the shift actuator and the shift rail for selectively biasing the shift rail in a first direction upon actuation of the shift actuator. The second biasing member is disposed between the housing and the shift fork for biasing the shift fork in a second direction that is substantially opposite the first direction.
