1. A continuously variable transmission (CVT) clutch, the CVT clutch comprising:
a post,
a fixed sheave mounted on a first end of the post in an axially fixed configuration;
a movable sheave mounted on the post, the movable sheave configured to selectively move axially on the post;
a reactive assembly configured to move the movable sheave based on at least one of a revolutions per minute (RPM) the CVT clutch is experiencing and torque the CVT clutch is experiencing;
a CVT gearing control assembly configured to move the movable sheave axially on the post independent of movement caused by the reactive assembly, the CVT gearing control assembly including,
an engaging member,
a slave cylinder housing forming an oil chamber that includes a plurality of slave push piston cylinders,
at least one oil line in fluid communication with the oil chamber, and
a slave push piston received in each slave push piston cylinder of the plurality of slave push piston cylinders in the slave cylinder housing, each slave push piston in operational communication with the engaging member, and
an actuator assembly including an actuator that is configured to adjust pressure in the at least one oil line to selectively move the movable sheave axially on the post independent of movement caused by the reactive assembly.
