Control solenoid valve, task - GF27.19-P-5111-01F
Transmission 722.9 in model 171.4, 203, 209, 211, 215, 219, 220, 230, 463.303/340/341 B2 brake control solenoid valve
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.
