Dorman 724-133 Transmission Oil Cooler Pressure And Return Line With Bypass Valve for Specific Chevrolet / GMC Models (OE FIX)

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.
