An integrated launch clutch and drive sheave for a continuously variable transmission (CVT) is provided. The integrated launch clutch and drive sheave includes a drive sheave, a launch clutch and an integrated hydraulic system. The drive sheave includes a fixed sheave member that is statically mounted on and rotationally fixed to a drive sheave post and a movable sheave member that is slidably mounted on the drive sheave post. The launch clutch is in rotational communication with a motor. The launch clutch is configured to selectively couple engine torque from the motor to the drive sheave post of the drive sheave. The integrated hydraulic system is configured to both activate the launch clutch to selectively couple engine torque between the motor and the drive sheave and to axially move the movable sheave member on the drive sheave post of the drive sheave in relation to the fixed sheave member.
