Abstract
A vehicle with a continuously variable transmission (continuously variable transmission) includes a torque responsive clutch having a cam and at least one coupling. The cam has a plurality of projecting surfaces, and a plurality of slots being defined between the projecting surfaces. The slots of the cam are used to direct cam followers that move across the slot surfaces as the vehicle is driven forward or in reverse. As the vehicle adjusts from forward to reverse or vice versa, the cam followers may jump from one side of the slot to the other.
