10L80 (GEN1&2) 10R80 CDF Drum Saver Kit | Sonnax
Ford 10R80 and GM 10L80 (Gen. 1 & 2) transmissions commonly suffer from the CDF drum sleeve shifting rearward, exposing fluid ports from behind the sleeve. This fluid loss leads to bump slides, neutral shifts, slide shifts and loss of 2nd Gear.
Installing Sonnax CDF drum saver kit 129910-01K restores proper CDF drum functionality. The step on the Sonnax sleeve prevents it from shifting rearward in the drum, and a set screw locks the sleeve from rotating. Whether installing to fix a shifted sleeve or using as a preventive solution, the Sonnax CDF drum saver kit is the key to avoiding CDF drum replacement.
