Sonnax case saver retainers are designed for 1999 and later GM 4L80-E units—and are the only intermediate clutch retaining ring case saver that allows the intermediate band to be retained. The case savers 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. Over the years there have been a variety of case saver designs, however, all required eliminating the intermediate band, as is often done in drag racing trans-brake applications. Only Sonnax case saver retainers support the intermediate clutch retaining ring yet are thin enough to allow the intermediate band to be installed to provide case lug protection in all applications.
