ABSTRACT:
A torque converter clutch has an engagement chamber and a disengagement chamber. The clutch engagement force, and therefore torque capacity of the clutch, is established by the pressure differential between the engagement and disengagement chambers. Fluid flow from the engagement chamber to the disengagement chamber is controlled by a sliding valve member operated on by opposing governor weights which are rotated with respective input and output members of the torque converter. The valve member can be controlled to effect complete clutch engagement if desired.
