• Reinforced outer case helps resist installation damage and adds durability
• Ribbed rubber inner diameter seals minor spindle imperfections and supports positive seating
• Internal contamination exclusion system helps keep debris out of the seal area
• Vent holes promote lubricant flow around the seal lip to reduce heat build-up

Detailed Description

Timken SL260001 is an automatic transmission output shaft seal engineered for dependable fluid control in the transmission case. Its reinforced construction and ribbed inner diameter are designed to maintain a secure seal on the shaft surface, while the contamination exclusion features help protect the sealing lip from debris that can contribute to leakage. For drivers servicing a Chevrolet Cobalt, Chevrolet Malibu, or Chevrolet Cavalier, this seal supports proper transmission sealing performance in the original application.

What This Part Helps Address

• Transmission fluid seepage at the output shaft
• Contamination entering the seal area
• Seal wear caused by heat build-up
• Leakage related to minor shaft surface imperfections
• Poor seal seating during transmission service

Installation Notes and Tips

• Verify the transmission application and output shaft seal location before installation.
• Inspect the shaft surface for scoring, burrs, or contamination before fitting the new seal.
• Clean the sealing bore and shaft area thoroughly so the seal seats evenly.
• Use proper seal installation tools to avoid damaging the outer case or sealing lip.
• Confirm the seal is fully seated and the area is free of leaks after service.
