GF27.19-P-5111-01F Control Solenoid Valve, Task

GF27.19-P-5111-01F Control solenoid valve, task
- Transmission 722.9
- Control solenoid valve brake B2

Component Identification:

The B2 brake control solenoid valve (VGS) (Y3/8y6) is actuated by the fully integrated transmission control (VGS) control unit (Y3/8n4) and influences the position of the B2/BR regulating valve. The pressure in the multi-disk brake B2 and pressure in the multi-disk brake BR depend on the regulating valve position and thus on the geometry of the regulating valve B2/BR.

The B2 brake control solenoid valve (VGS) (Y3/8y6) has a rising characteristic. This means that the oil pressure applied in the B2/BR regulating valve increases 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 B2 brake control solenoid valve (VGS) (Y3/8y6) thus supplies no pressure.
