Lubricating Pressure, Function

Operation

The working pressure regulating valve diverts surplus oil to the lubrication pressure regulating valve, from
where it is controlled and used for lubricating and cooling the mechanical transmission and torque converter. In
addition the pressure in the torque converter is limited via the lubrication pressure.

Shift Pressure, Function

Operation

The shift pressure is determined by the shift pressure regulating solenoid valve (Y3/6y2) and the shift pressure
regulating valve.

The shift pressure:



Regulates the pressure in the activating shift element during the shift phase.



Determines together with the modulating pressure the pressure reduction at the deactivating shift element

as regulated by the overlap regulating valve.



Initializes 2nd gear in limp-home mode.

Modulating Pressure, Function

Operation

The modulating pressure influences the size of the working pressure and determines together with the shift
pressure the pressure regulated at the overlap regulating valve.

The modulating pressure is regulated at the modulating pressure regulating solenoid (Y3/6y1), which is under
regulating valve pressure. The modulating pressure via variable and relative to the engine load.
