A controlled lock-up clutch interposed between the impeller and turbine in a torque converter of an automatic transmission for an automotive vehicle where the clutch lock-up and unlock is controlled at a torque converter speed ratio design point by the stator movement and loading. A lock-up clutch is actuated from a hydraulic source and controlled by a rotary valve that is actuated by a one-way overrunning clutch positioned between the stator of the torque converter and the rotary valve movable between two control positions.
