National 710590 Automatic Transmission Output Shaft Seal - Left

Automatic Transmission Output Shaft Seal

National 710590 is an automatic transmission output shaft seal built for metric applications that require a precise housing and shaft fit. It uses a fluoro-elastomer sealing material and a bi-directional lip design to help maintain a consistent seal at the transmission output shaft.

Compatible with select Volvo, Ford, Lincoln, Mazda, and Mercury vehicles equipped with Aisin TF-80SC or TF-82SC transmissions, this seal is specified for left-side applications where the listed OE dimensions match. National 710590 is also referenced by OE and aftermarket part numbers for the same application.

What This Seal Helps Address

• Transmission fluid seepage at the output shaft
• Fluid loss caused by a worn or hardened seal lip
• Leakage around the housing bore when the original seal no longer seats correctly
• Service replacement needs on Aisin TF-80SC and TF-82SC equipped vehicles
• Noise or contamination concerns related to a compromised transmission seal

Installation Notes and Tips

Verify the transmission code, shaft diameter, housing bore, and side before installation. This seal is specified for left-side applications and metric dimensions, so matching the OE measurements is important for proper seating and sealing. Inspect the shaft surface and housing for wear, scoring, or debris before installing National 710590.

For Volvo S60, S80, XC60, XC70, and XC90 applications, as well as Ford Fusion, Lincoln MKZ, Mazda CX-7, Mazda CX-9, Mazda 6, and Mercury Milan listings, confirm the transmission variant shown in the fitment notes before ordering.

Quality Assurance

National has supplied sealing solutions for more than 75 years and continues to develop products for current vehicle service needs. The 710590 seal reflects that focus with a fluoro-elastomer design and OE-style dimensional accuracy for the listed applications.
