Regulating Valve Pressure Regulating Valve
The regulating valve pressure regulating valve
(Fig. 72) is located in the valve housing of the elec-
trohydraulic control module. It regulates the regulat-
ing valve pressure (p-RV).
Shift Valve Pressure Regulating Valve
The shift valve pressure regulating valve (Fig. 73)
is located in the valve housing of the electrohydraulic
control module. It regulates the shift valve pressure
(p-SV).
OPERATION
ELECTRICAL CONTROL UNIT
Signals from the transmission control module
(TCM) are converted into hydraulic functions in the
electric valve control unit (7) (Fig. 74). The RPM sen-
sors (1, 12), starter interlock contact (9), and trans-
mission oil temperature sensor (8) of the electric
valve control unit (7) supply the TCM with input sig-
nals. The solenoid valves are controlled by the TCM
and trigger the hydraulic functions.
