• Noise or shifting concerns tied to fluid loss

Installation Notes and Tips

Confirm shaft diameter, outside diameter, and seal width before installation. Inspect the shaft surface for grooves, scoring, or corrosion that can shorten seal life. Clean the bore and sealing surface thoroughly, and install the seal squarely to avoid distortion. Verify the transmission fluid level after service and check for leaks during the first road test.
