Detailed Description

This Timken transmission seal is engineered for torque converter sealing service where fluid retention and contamination control are critical. The reinforced case supports installation, while the ribbed inner diameter helps the seal conform to minor shaft surface imperfections for a tighter fit. Timken 6879H is a practical replacement for vintage Chrysler and Dodge drivetrains, including Chrysler Imperial, Chrysler New Yorker, and Dodge Dart applications from the listed model years.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Solve

• Transmission fluid leakage at the torque converter seal area.
• Contamination entering the seal interface and affecting sealing performance.
• Seal damage during installation on older transmission housings.
• Minor shaft or spindle surface imperfections that can interfere with seating.
• Heat buildup around the seal lip during operation.

Installation Notes and Tips

Verify transmission case dimensions and seal orientation before installation. Clean the sealing bore and shaft surface thoroughly, and inspect for wear, scoring, or burrs that could affect sealing. Use proper installation tools to avoid distorting the seal case or lip. Confirm vehicle application by year, make, and model before ordering Timken 6879H.
