Abstract
A two stage clutch and shift actuation paddle assembly provides clutch disengagement through a first range of movement of a manually operated control lever or paddle and electronic shifting of a transmission upon movement through a second range. A return spring force generator causes a lower return force to be exerted on the generator paddle in a range of motion wherein the clutch is disengaged and a pronounced increased spring force to be exerted in advanced range of motion wherein the transmission shift actuation occurs.
