Symptoms:

  • Worn OD servo pin bore in case
  • Burnt OD band
  • 3-4 Flare

Cause:

Severe wear of the case at the servo apply pin bore due to continuous pin oscillation can result in burned clutches, shift complaints, and destroyed cases.

Correction:

The Sonnax sleeve is made from highly wear-resistant aluminum, and allows the case to be refurbished to provide proper clearance with the servo apply pins.
