Torque Converter Lockup Clutch Control Pressure, Function

Apart from extreme states of open or closed, it is possible to operate the torque converter lockup clutch with preset slip speeds. To enable this variable control pressure must be applied to the torque converter lockup clutch regulating valve.

The torque converter lockup clutch control pressure is adapted to each operating state via the pulse-width modulated torque converter lockup solenoid valve (Y3/6y6) which is actuated by the ETC control unit (N15/3).
