Abstract
A clutch control assembly for a transmission, including a piston plate including a first side having a first circumferentially aligned and axially extending ramp, and a second side. The assembly includes an adjustment ring in contact with the first ramp, and at least one rotary piston with a first end fixed to the adjustment ring. In response to a first force applied to the second radially disposed side and the at least one rotary piston, the at least one rotary piston is displaceable to urge the adjustment ring in a first circumferential direction along the first ramp such that the adjustment rings displaces in a first axial direction away from the piston plate.
