Installation Notes and Tips

Verify the shaft diameter, housing bore, and transmission family before installation. Clean the bore and shaft surface thoroughly, and inspect for scoring or wear that could affect sealing. Confirm the transmission code and application notes, especially on Toyota Tacoma, Toyota Pickup, Jeep Wrangler, and Dodge Dakota models with Aisin transmissions. Proper alignment during installation helps prevent lip damage and premature leakage.
