Shift Solenoid: Description and Operation
GF27.19-P-5111-01E Control Solenoid Valve, Task
GF27.19-P-5111-01E Control solenoid valve, task
- TRANSMISSION 722.9
- Control solenoid valve brake B1
Component Identification
The brake control solenoid valve B1 (VGS) (Y3/8y5) is actuated by the fully integrated transmission control unit (VGS) (Y3/8n4) and influences the
position of the regulating valve B1. The pressure in the multidisk brake B1 depends on the regulating valve position and therefore on the geometry of
the regulating valve B1.
The B1 brake control solenoid valve (VGS) (Y3/8y5) has a lowering characteristic. This means that the oil pressure applied in the regulating valve B1
reduces 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 brake control solenoid valve B1 (VGS) (Y3/8y5) thus supplies maximum pressure.
