Under extreme pressure or temperature conditions, the converter/lube circuit in listed Chrysler RWD units can be restricted by the pressure regulator 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 This outdated technique contributes to slow engagements or, if the hole is improperly drilled, excessive converter pressure and low line pressure.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 regulated pressure regulator valve 22771A-02K, which ensures oil flow under extreme operating conditions and prevents drainback when the vehicle is off.

• Improves converter feed/lube oil flow at critical low RPM and high load conditions
• Redesigned valve prevents fluid drainback and 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
• Drop-in Zip Valve™ installs quickly and easily
