Chrysler Crossfire. Manual — part 786
Regulating Valve Pressure Regulating Valve
The regulating valve pressure (p-RV) is set at the reg-
ulating valve pressure regulating valve (1) in relation
to the working pressure (p-A) as far as the maximum
pressure.
Shift Valve Pressure Regulating Valve
The non-constant regulating valve pressure (p-RV) is
regulated to a constant shift valve pressure (p-SV) at
the shift valve pressure regulating valve (1) and is
used to supply the 1-2 and 4-5 / 3-4 / 2-3 solenoid
valves and the torque converter lockup clutch PWM
solenoid valve.
