GF27.20-P-5101-02SK Torque Converter Lockup Clutch, Function

GF27.20-P-5101-02SK Torque converter lockup clutch, function
- Transmission 722.6

Component Identification:

When actuated by the ETC control unit (N15/3), oil pressure controlled by the torque converter lockup PWM solenoid valve (Y3/6y6) is directed through the input shaft (1) to the pressure chamber behind the piston (16d). The piston presses the clutch pack (16c) together and allows torque to be transferred directly between the impeller (P) and turbine wheel (T).

The torque converter lockup clutch is activated in all forward gears in relation to the engine speed and engine load.
