• Service replacement for worn OE-style output shaft seals

Installation Notes and Tips

Confirm the transmission code, shaft diameter, housing bore, and seal width before installation. Clean the bore and shaft surface thoroughly, and inspect for scoring or wear that could affect sealing. For best results, install the seal squarely to avoid distortion of the nitrile lip and verify the transmission application against the exact model, year, and transmission listed.
