ABSTRACT:
A lock-up system for an automatic transmission torque converter including a single movable piston disposed axially between a housing fixed to the torque converter impeller and the torque converter turbine, normally held in a free position by transmission regulated fluid forces and movable in response to a reversal of the fluid forces acting on it to a position where frictional sealing surfaces on the piston and the housing effect a mechanical interconnection of the turbine and impeller.
