Torque Converter Clutch Lock-Up OFF (Disengaging Torque Converter Clutch)

When the fluid pressure to the lock-up fluid passage (94) in the torque converter is blocked, the torque converter clutch in the torque converter is released. The turbine and the torque converter cover are also released at this time, causing the mainshaft and the engine crankshaft to rotate at a different speed.
