    Reverse Servo Sleeve Kit
    Part No. 56532-01K

    The reverse servo bore found on the case of listed Ford transmissions can become scored due to repeated oscillation of the reverse servo piston within the bore during normal operation. Once this bore is damaged, the case must be scrapped. Install the Sonnax reverse servo sleeve kit 56532-01K to refurbish the case bore. Instructions are included for machining the servo piston assembly by simply turning the smaller piston journal 1/16" smaller.

    • O-Ring

    Symptoms:

    • Reverse band failure
    • Rear servo bore wear
    • Forward clutch failure
    • Delayed Forward clutch

    Cause:

    Heavy scoring at the case bore for the inner piston seal allows drive oil loss, which can cause forward clutch and/or reverse band failure.

    Correction:

    The reverse servo sleeve kit restores the function of the reverse piston and salvages the case.
