  Seal, BRS158

• Description:

  This Genuine Ford automatic transmission output shaft seal installs at the rear extension housing of the transaxle, sealing around the output shaft where it exits toward the driveline. It keeps transmission fluid contained and prevents dirt and moisture from entering the housing bore, protecting internal components from contamination. Ford catalogs this passenger-side (right-hand) seal under the output shaft seal family, and it serves the 6F-series automatic transmissions used across a wide range of Ford, Lincoln and Mercury vehicles from the 2009 through 2022 model years, making it a broadly shared service seal rather than a single-vehicle part. A failing output shaft seal typically announces itself with reddish transmission fluid weeping or dripping from the rear of the transaxle, fluid spots under the vehicle after parking, a gradual drop in fluid level, or a burnt smell if the level falls far enough to affect shift quality. Replacing this seal during axle, half-shaft or transmission service restores a clean, leak-free interface and helps preserve correct fluid level. The seal is a precision molded lip seal designed to Ford specification for the correct shaft diameter and bore depth; it should be seated squarely to full depth with the lip facing inward and the sealing surface lightly lubricated during installation to avoid damaging the lip. As a genuine Ford component it matches original fit and material for dependable, long-term sealing.
