• Fits right-side output shaft applications on select Aisin TF-80SC transmissions.

Detailed description

This National output shaft seal is engineered around the listed shaft, bore, and width dimensions to support a proper seal at the transmission output shaft. The bi-directional lip design helps maintain contact at the sealing edge, while the polyacrylate material is selected for transmission service conditions. For buyers searching for a transmission output shaft seal for Cadillac XT5, Buick Verano, or Chevrolet Cruze fitment, National 711037 provides a direct replacement option with application-specific coverage.

National has more than 75 years of sealing experience, and the 711037 reflects that focus on modern drivetrain sealing needs. The 711000 series is positioned as a premium sealing solution line for current vehicle platforms, with dimensional accuracy and material selection centered on leak control and long-term serviceability. This part cross-references Monroe Shocks & Struts (e.g., 0374595, 374595) for the same application.

What it is used for

• Stopping transmission fluid seepage at the output shaft.
• Replacing a worn or hardened seal surface.
• Addressing leaks around the transmission housing bore.
• Restoring sealing performance after service or disassembly.
• Supporting proper operation in Aisin TF-80SC-equipped vehicles.

Installation notes and tips

Verify the transmission type, shaft diameter, housing bore, and width before installation. This seal is listed for right-side applications only, so confirm the vehicle and transmission match the fitment data before ordering. Clean the sealing bore and shaft surface thoroughly, and inspect for wear or scoring that could affect seal life.
