Valve, Lube Regulated Pressure, 42-47RH/RE,48RE,A727,A904, Chrysler,Dodge, 78-UP

In Chrysler RWD units, the cooler/converter charge circuit is not opened until the pressure regulator valve moves far enough to flow oil. The industry fix of drilling a small orifice between line pressure and cooler circuit ensures fluid to the converter/lube circuit, but the hole also increases the converter drainback problem because ATF can drain out through the orifice when the engine is turned off.

Features & Benefits

Pressure regulator valve 22771A-02K is designed with an internal check valve that allows oil to flow into the converter charge circuit as soon as vehicle is started.
Improves converter feed/lube oil flow at critical low RPM and high load conditions.
With engine off, check valve prevents fluid from draining out of orifice, reducing converter drainback.

Note: Valves are designed for all 94 and later 42-46-47RE Chryslers but can be used in 78 & later RH units and A904 & A727 units with TCC when the original PR valve design matches the Sonnax valve.
