Function
The torque converter lockup clutch regulating valve regulates the converter lockup clutch working pressure depending on the torque converter lockup clutch control pressure. Depending on the level of the torque converter lockup clutch working pressure the torque converter lockup clutch is engaged, disengaged or in slip mode. In the lower position of the torque converter lockup clutch regulating valve lubricating oil flows through the torque converter and oil cooler into the transmission (torque converter lockup clutch unpressurized).

In its control position (slip mode, pressure applied to torque converter lockup clutch) a reduced lubricating oil flows through annular gap, bypassing the torque converter, directly through the oil cooler into the transmission. The other part of the lubricating oil is lead into the torque converter via the throttle to cool the torque converter lockup clutch.
