Symptoms:

  • 2nd Clutch burned (GM)
  • Burnt band (GM)
  • 3rd Clutch burned
  • 2-3 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 servo pin bore sleeve is made from highly wear-resistant aluminum and allows the case to be refurbished to provide proper clearance with the servo apply pins.
