Function of Torque Converter Lock-Up Clutch Control Pressure

FUNCTION
- Apart from the extreme conditions open or closed it is possible to operate the torque converter lock-up clutch at specified slip speeds. To make this possible, variable control pressure must be applied to the torque converter lock-up clutch regulating valve.

- The torque converter lock-up clutch control pressure (p-S/torque converter lock-up) is adapted to the respective operating condition via the pulse-width-modulated solenoid valve of the torque converter lock-up clutch (Y3/6y6) which is actuated by the Electronic Transmission Control (ETC) Module.
