    Boost Valve Spring Retainer
    Part No. 22990-01

    Package Quantity: 5

    When listed Chrysler units feature a TCC boost valve lineup, the OE retainer is prone to cracking and breaking, allowing the the boost valve and spring to fall out of position. This causes a leak of 4th Gear and TCC oil pressure. Sonnax boost valve spring retainer 22990-01 eliminates this leakage by securely keeping the valve and spring in place. It is made from steel for greater durability than the OE retainer.

    Symptoms:

    • Leakage of 4th & TCC oil pressure
    • Slipping gears

    Cause:

    The U-shaped bracket at the top of valve body that retains the boost valve and spring breaks, allowing the spring and valve to fall out of position.

    Correction:

    The Sonnax replacement bracket resists cracking or breaking.
