Control solenoid valve component description - GF27.19-P-5147CWH

TRANSMISSION 722.9 in MODEL 204.0 up to Model Year 8 

Adjustment solenoid lock-up clutch 

Location 

The torque converter lockup clutch control solenoid valve is mounted on the fully integrated transmission control controller unit.

Task 

The torque converter lockup clutch control solenoid valve is actuated by the fully integrated transmission control unit and influences the position of the torque converter lockup clutch regulating valve. The clutch pressure in the torque converter lockup clutch depends on the regulating valve position and thus on the geometry of the torque converter lockup clutch regulating valve. The torque converter lockup clutch control solenoid valve has a rising characteristic.

This means that the oil pressure applied in the torque converter lockup clutch regulating valve increases as the actuation current increases. In limp-home mode of the fully integrated transmission control (VGS) all the control solenoid valves are de-energized. The torque converter lockup clutch control solenoid valve thus supplies no pressure.

Body 

In the torque converter lockup clutch control solenoid valve, a proportional solenoid converts the electrical signals from the fully integrated transmission control unit. The float needle can also be moved into intermediate positions as a result.

Function 

The torque converter lockup clutch control solenoid valve assigns a proportional pressure to the current which is controlled by the fully integrated transmission control unit.
