Installation Notes and Tips

Verify the shaft diameter, outside diameter, and width before installation. Inspect the sealing surface and surrounding transmission components for wear, scoring, or contamination before fitting the new seal. Confirm the transmission type listed in the fitment notes, especially A4LD-E, Mitsubishi, and ZF applications, to ensure correct application matching.
