Abstract
A transmission including a ring gear engageable with clutch teeth. A shift fork connected to a cam roller is engageable with the ring gear. The cam roller includes at least one V-shaped groove, and an element is disposed between the V-shaped groove of the cam roller and a base of the shift fork such that rotation of the cam roller translates into displacement of the shift fork and the ring gear.
