Listed Chrysler transmissions often suffer delayed engagement, converter bushing failure, overheated converters and dragging Forward clutches. These symptoms can be a direct result of the design of the OE manual valve, which does not allow converter or cooler charge in Park. Sonnax manual valve 22771-09 is engineered to overcome the OE shortcoming by allowing fluid into these critical circuits when in Park.
For maximum benefit, installing Sonnax lube-regulated pressure regulator valve 22771A-02K along with Sonnax manual valve is recommended.

Redesigned, patented valve alleviates cooler/converter starvation
Case-hardened steel valve combats premature wear
No reaming or special tools required
22771A-02K and Sonnax 22771-09 can be used independently but are of greatest benefit when used as a pair
