Address symptoms caused by inadequate OE design and introduce converter/cooler charge in Park by installing upgraded Sonnax manual valve.
For use in conjunction with '78-later pressure regulator valve only; see instructions for details.
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, recommend installing Sonnax lube-regulated pressure regulator valve 22771A-02K along with Sonnax manual valve.
