Installation Notes and Tips
Confirm shaft diameter, outside diameter, and seal width before installation. Inspect the shaft surface for grooves, scoring, or corrosion, since seal performance depends on a clean sealing surface. Clean the bore and surrounding area thoroughly, and install the seal squarely to avoid distortion. Verify the transmission is the rear-position application listed for your BMW or Dodge model before final assembly.
