Detailed Description

This Timken automatic transmission torque converter seal is designed for service on the 1999 Acura TL. The seal’s construction focuses on maintaining a tight seal at the torque converter interface while helping keep contaminants out of the transmission area. Timken 417486 is a practical replacement choice when the original seal shows wear, hardening, or leakage.

This part cross-references Bosch 18124 for the same application.

What It Helps Fix

• Transmission fluid leaking at the torque converter seal area
• Contamination entering the sealing surface
• Seal wear from heat and age
• Leakage caused by minor spindle surface imperfections
• Reduced sealing performance after transmission service

Installation Notes and Tips

Inspect the sealing surface before installation and replace any worn or damaged components that could affect the seal lip. Clean the bore and shaft area thoroughly, and install the seal squarely to avoid distortion. For 1999 Acura TL automatic transmission service, verify the old seal dimensions and seating depth before final assembly. Timken 417486 should be installed with care to preserve the reinforced case and sealing lip.

Quality Assurance

Timken oil and grease seals use precision sealing designs, reinforced construction, and contamination-control features to support reliable service life in transmission applications.
