OE valve must match '78-later design
Under extreme pressure or temperature conditions, the converter/lube circuit in listed Chrysler RWD units can be restricted by the PR valve. The practice of drilling a hole between passages is problematic. This outdated technique contributes to slow engagements or — if the hole is improperly drilled — excessive converter pressure and low line pressure.
The best way to improve oil flow is to replace the OE valve with Sonnax lube regulator pressure regulator valve 22771A-02K, which ensures oil flow under extreme operating conditions and prevents drainback when the truck is off.
Improves converter feed/lube oil flow at critical low RPM and high load conditions
Redesigned valve prevents fluid drainback & slow engagements
Helps charge the converter in Park
22771A-02K and Sonnax 22771-09 can be used independently, but are of greatest benefit when used as a pair PR valve/manual valve pair
