| The working pressure control solenoid valve (VGS) (Y3/8y1) is actuated by the fully integrated transmission control (VGS) 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 (VGS) (Y3/8y1) 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 (VGS) (Y3/8y1) thus supplies the maximum pressure. |
