Abstract
A torque converter and lock-up clutch wherein the fluid flow to and from the torque converter is directed into the converter, at an inner location, between the stator and turbine and to the disengagement of the clutch, when the clutch is disengaged. A control valve disposed in the turbine shaft divides the inlet flow. The fluid is exhausted from the converter between the stator and impeller. When the clutch is engaged, fluid flow is directed to the converter between the stator and impeller and the disengagement chamber of the clutch is exhausted. The control valve, during this phase, prevents fluid from exhausting between the stator and turbine.
