GF27.19-P-5111-01B Control solenoid valve, task
- Transmission 722.9
- Control solenoid valve coupler K1

Component Identification:

The clutch control solenoid valve K1 (VGS) (Y3/8y2) is actuated by the fully integrated transmission control unit (VGS) (Y3/8n4) and influences the position of the regulating valve K1. The pressure in the multidisk clutch K1 depends on the regulating valve position and therefore on the geometry of the regulating valve K1

The K1 clutch control solenoid valve (VGS) (Y3/8y2) has a rising characteristic. This means that the oil pressure applied in the K1 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 K1 clutch control solenoid valve (VGS) (Y3/8y2) thus supplies no pressure.
