Component Identification:

Location
The multidisk brake control solenoid valve B2 is mounted on the fully integrated transmission control controller unit.

Component Identification:

Task
The multidisk brake control solenoid valve B2 is actuated by the fully integrated transmission control control unit and influences the position of the regulating valve B2/BR. 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 multidisk brake control solenoid valve B2 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 multidisk brake control solenoid valve B2 thus supplies no pressure.

Body
In the multidisk brake control solenoid valve B2, a proportional solenoid converts the electrical signals from the fully integrated transmission control control unit. The float needle can also be moved into intermediate positions as a result.

Function
The multidisk brake control solenoid valve B2 assigns a proportional pressure to the current which is controlled by the fully integrated transmission control control unit.
