National 710732 Automatic Transmission Output Shaft Seal - Left or Right

Automatic Transmission Output Shaft Seal

National 710732 is an automatic transmission output shaft seal built for metric applications that require a precise sealing surface and stable lip contact. It uses PTFE material and a counter-clockwise spiral lip design to help maintain sealing performance in Toyota, Lexus, Scion, and Pontiac applications.

With a 50.000 mm inside diameter, 68.200 mm outside diameter, and 9.000 mm width, this seal is sized for specific output shaft and housing bore dimensions. National 710732 is a direct-fit sealing component for left-side transmission applications across a wide range of Toyota Camry, RAV4, Highlander, and Lexus ES350 fitments.

Installation Notes and Tips

Confirm the shaft diameter, housing bore, and transmission type before installation. This seal is specified for left-side applications in the listed vehicles, and some fitments include transmission-specific notes such as Toyota P410, U250E, U240E, or U241E configurations. Inspect the shaft surface for wear, scoring, or contamination before installing the new seal.

For best results, keep the sealing lip clean during installation and avoid damaging the PTFE lip edge. Verify that the seal is seated squarely in the bore and that the output shaft surface is within specification for the application.
