Shift Pressure (P-S)

The shift pressure is determined by the shift pressure regulating solenoid valve 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.
