4L80E / 4L85E Case Saver Retainer, Sonnax 34762-20. 

Sonnax 4L80E Case Saver Retainer 34762-20 for ’99-later GM 4L80-E and 4L85-E transmissions is the only intermediate clutch retaining ring case saver that allows the intermediate band to be retained. This case saver can fit over the intermediate band anchor lug inside the case and extends rearward to support the intermediate clutch backing plate retaining ring, preventing case lug blow out. There have been a variety of case saver designs over the years. However, all require eliminating the intermediate band as is often done in drag racing trans-brake applications. Lastly, only the Sonnax case saver retainer supports the intermediate clutch retaining ring, yet is thin enough to allow the intermediate band to be installed, allowing case lug protection in all applications.

  • Protects case lugs from blow out
  • Salvages cases with one or two blown lugs
  • Use with or without intermediate band

  • See instructions for details on identifying ’99-later 4L80-E applications.
  • Requires modifications to OE-style intermediate clutch backing plates without a full complement of case lugs. No modifications are required when used with Sonnax heavy duty intermediate clutch backing plate 34144HD-02.
