Installation Notes

Verify transmission model and seal location before installation, since fitment includes N/A, Front, and Outer positions depending on application. Confirm the vehicle-specific transmission family, including notes such as Only Fits A518 or Only Fits A727 where listed. Clean the sealing surfaces thoroughly and inspect the pump bore and related components for wear before installing the new seal.
