Installation Notes and Tips

Verify the transmission model and seal dimensions before installation, especially on Ford 5R110-equipped vehicles. Inspect the pump bore and sealing surface for scoring, corrosion, or debris before fitting the new seal. Clean the area thoroughly and confirm the seal seats evenly to avoid distortion during assembly. Use the vehicle application data and the part number SS2997 to confirm the correct replacement before reassembly.
