ABSTRACT:
A system for actuating couplers to produce gear changes in a motor vehicle transmission includes first and second actuator drums supported for rotation, and first and second shift forks. Each first shift fork is driveably connected to a first actuator drum, secured to a first coupler, and displaced in response to rotation of a first actuator drum between a neutral state, wherein no gear is engaged, and at least one first drive state, wherein a gear of a first gear group is engaged. Each second shift fork is driveably connected to a second actuator drum, secured to a second coupler, and displaced in response to rotation of a second actuator drum between a neutral state, wherein no gear is engaged, and at least one second drive state, wherein a gear of the second gear group is engaged.
