    Servo Sleeve Kits

    • Servo Piston
    • Sleeve
    • PTFE Seal

    The intermediate servo bore becomes scored from repeated cycling. The spring side of the piston has line pressure present in R, N, D. Excess leakage at the servo piston results in low line pressure and delayed engagements. During forward speeds, oil loss affects shift quality and reduces clutch life. To salvage cases install Sonnax intermediate servo sleeve kit 35709-01K.

    • Kit contains an aluminum sleeve and a replacement piston with a PTFE seal.
    • This kit is a simple drop-in solution and requires no machining of the transmission case.


    Manufacturer's Part Number:

    In high performance applications where a larger servo is desired, the Sonnax Servo Kits provide a larger apply area. The Sonnax servo is calibrated to progressively increase band apply force as line pressure increases. Sonnax servos are the perfect upgrade for more holding power without excessively harsh shifts.
