• Reinforced outer case resists installation damage and adds durability
• Ribbed rubber inner diameter helps seal minor spindle imperfections and improve seating
• Internal contamination exclusion system helps reduce debris penetration that can lead to leakage
• Vent holes promote lubricant flow around the seal lip to help manage heat build-up

Detailed Description

Timken 710636 is an automatic transmission output shaft seal for select Chevrolet, GMC, Cadillac, and Hummer applications. It is engineered for a secure fit at the output shaft, where sealing integrity is critical to keeping transmission fluid contained and contaminants out. This part is a direct-fit service component for vehicles including the Chevrolet Silverado 1500, GMC Sierra 1500, and Chevrolet Tahoe.

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

Common Repair Uses

• Transmission fluid leakage at the output shaft area
• Contamination entering the transmission through a worn seal

Installation Notes and Tips

Inspect the shaft surface before installation and clean the sealing area thoroughly.
