Dorman 724-133 Transmission Line 09-13 Chevy Silverado 1500 GMC Sierra 1500

The original equipment automatic transmission oil cooler line assembly on certain Chevrolet Silverado and GMC Sierra trucks uses crimped connections between the lines and the bypass valve. That means that when a line leaks or fails from rust or fatigue, the dealer's only repair solution is to replace the entire assembly. This Dorman OE FIX assembly replaces the crimped connection with a threaded connection for simple and less expensive serviceability than the factory design, and ensures a secure, leak-free seal for proper fluid flow that helps protect the transmission.

• Serviceable assembly - this innovative automatic transmission oil cooler hose assembly replaces the factory design's crimped line connection with threaded connections for serviceability
• Cost-effective - replacing the original equipment assembly with this serviceable assembly can help reduce long-term operating and maintenance costs for fleets and vehicle owners
• Restores function - engineered and manufactured to help ensure a secure, leak-free seal for proper fluid flow that helps protect the transmission
• Direct replacement - designed to match the performance of the original equipment assembly on specified Chevrolet Silverado and GMC Sierra trucks
