A mechanical release system for a ball ramp actuator is disclosed where the ball ramp actuator generates a clamping force on a driveline clutch when a control ring is rotated relative to an activation ring thereby causing a rolling element to traverse a pair of opposed ramps to axially expand the separation between the control ring and the activation ring to generate the clamping force. The ball ramp actuator is axially contracted and the driveline clutch is released using a relatively low release force level when the driver causing a rotation of a release arm which contacts a release bearing thereby causing a rotatable connected stop ring to axially move and release a control clutch which when engaged, frictionally connects the control ring to the transmission input shaft. A clamping spring acting upon the stop ring and a drive ring thereby supplying a clamping load on a control disc between the drive ring and a control collar within the control clutch thereby engaging the ball ramp actuator and the driveline clutch.
