Valve Body Detent Ball & Sleeve Kit
Part No. 22771-12K

Kit is designed to fit both the short and long OE detent bore designs.

    Tooling Required:
  • 22771-TL12
The detent ball in the valve body wears into the aluminum bore due to continuous movement and vibration of the linkage. This creates excessive looseness in the manual valve lever and allows the manual valve to move out of alignment. No start or being stuck in Park can occur from the manual valve being out of position due to extra clearance. This condition often requires that the valve body be replaced.

Sonnax valve body detent ball and sleeve kit 22771-12K allows the valve body to be salvaged. The bore must be oversized using the self-guiding bench reamer included in Sonnax tool kit 22771-TL12. A .096" diameter drill bit is also included to allow the retaining pin hole to be redrilled for use with the OE pin. Sonnax detent spring 22771-36 is also available.

  • Precision steel sleeve restores worn valve body and properly supports the detent ball.
  • Precision-ground steel ball included for optimal fit with the replacement sleeve.
  • Self-guiding bench-style reamer allows casting to be oversized quickly and accurately without specialized equipment.

Although this fix is compatiblewith 48RE units, the bore diameter in some units will be smaller and may cause potential reamer piloting issues.

  • Sleeve
  • Ball

Symptoms:

  • Manual lever binds in Park position
  • Damaged valve body casting
  • Linkage loose
  • No start

Cause:

Continuous movement and vibration of the shift linkage causes wear to the valve body detent ball bore

Correction:

By oversizing the detent ball bore and installing this precision steel sleeve and replacement ball, expensive cores may be salvaged.
