Abstract
A continuously variable transmission (CVT) clutch is provided that includes a CVT gearing control assembly that is configured to move a movable sheave of the CVT clutch axially on a post independent of movement caused by a reactive assembly of the CVT clutch. A slave cylinder housing of the CVT gearing control assembly forms an oil chamber that includes a plurality of slave push piston cylinders. A slave push piston is received in each slave push piston cylinder in the slave cylinder housing. Each slave push piston is in operational communication with an engaging member that is configured to selectively engage and move the movable sheave. An actuator assembly adjusts pressure to selectively move the slave push pistons.
