Component Identification:

Location
The working pressure control solenoid valve is mounted on the fully integrated transmission control controller unit.

Task
The working pressure control solenoid valve is actuated by the fully integrated transmission control control unit (Y3/8n4) and influences the position of the working pressure regulating valve. The working pressure depends on the regulating valve position and thus on the geometry of the working pressure regulating valve. The working pressure control solenoid valve has a falling characteristic. This means that the oil pressure applied in the working pressure regulating valve reduces as the actuating current increases. In limp-home mode of the fully integrated transmission control (VGS) all the control solenoid valves are de-energized. The working pressure control solenoid valve thus supplies maximum pressure.

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

Function
The working pressure control solenoid valve assigns a proportional pressure to the current which is controlled by the fully integrated transmission control control unit.
