relation to the load and gear. All other pressures Lubrication Pressure (p - Sm) At the working pressure regulating valve surplus oil is diverted to the lubrication pressure regulating Shift Pressure (p - S) The shift pressure is determined by the shift pres- sure regulating solenoid valve and the shift pressure • Regulates the pressure in the activating shift element during the shift phase. • Determines together with the modulating pres- sure the pressure reduction at the deactivating shift • Initializes 2nd gear in limp-home mode. Modulating Pressure (p - Mod) The modulating pressure influences the size of the working pressure and determines together with the Regulating Valve / Control Valve Pressure (p - RV) The regulating valve pressure is regulated at the regulating valve pressure regulating valve in relation Shift Valve Pressure (p - SV) The shift valve pressure (p-SV) is derived from the regulating valve pressure (p-RV), is regulated at the • 1-2 and 4-5 shift solenoid valve. • 3-4 shift solenoid valve. • 2-3 shift solenoid valve. • Torque converter lockup solenoid valve. • 3-4 and 2-3 shift pressure shift valve. mand valves via the upshift/downshift solenoid valves. Overlap Pressure (p - Ü) The overlap pressure controls the shift component pressure reduction during a shift phase.
