What It Helps Address

• Transmission fluid leakage at the input shaft seal area
• Contamination entering the transmission through a worn dust lip
• Seal wear from age, heat, and shaft movement
• Service replacement for a leaking automatic transmission main shaft seal
• Fitment correction when the original seal dimensions no longer hold properly

Installation Notes and Tips

Confirm the transmission code, shaft diameter, and seal dimensions before installation. Match the 46.5 mm inner diameter, 60 mm outer diameter, and 18 mm height to the removed part, and verify the right-hand twist swirl type and dust lip configuration. Clean the shaft and seal bore thoroughly before pressing the seal into place to avoid damage to the sealing edge.

Because this is a transmission input shaft seal, careful alignment during installation is important to prevent premature leakage. Always compare the old seal and OE reference before final assembly on Audi A4, Audi A5, Audi A6, Audi Q5, and Volkswagen GTI or Tiguan applications.

Quality Assurance

Elring is known for sealing-system components used in automotive service applications, and this seal is built to the listed OE-style dimensions and design specifications. Verify fitment against the vehicle and transmission details before installation.
