GF27.19-P-5111-01G Control solenoid valve, task
- Transmission 722.9
- Control solenoid valve brake B3

Component Identification:

The brake control solenoid valve B3 (VGS) (Y3/8y7) is actuated by the fully integrated transmission control unit (VGS) (Y3/8n4) and influences the position of the regulating valve B3. The pressure in the multidisk brake B3 depends on the regulating valve position and therefore on the geometry of the regulating valve B3

The B3 brake control solenoid valve (VGS) (Y3/8y7) has a rising characteristic. This means that the oil pressure applied in the B3 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 B3 brake control solenoid valve (VGS) (Y3/8y7) thus supplies no pressure.
