Product Description

On certain Chevrolet, GMC, and Cadillac trucks and SUVs, when the transmission overheats, doesn't generate sufficient heat, or leaks fluid, it can be due to the failure of the original equipment transmission bypass valve. The factory valve design is notoriously vulnerable to corrosion, clogging, and wax motor failure, design flaws reflected in a GM service bulletin. This direct replacement Dorman OE FIX valve is upgraded to more effectively optimize cooler and transmission performance and provide a more permanent repair. Machined from solid aluminum billet for enhanced corrosion resistance, the housing features a threaded cap that protects the bore and seals and eliminates the OE snap ring design, which is prone to corrosion that can lead to complete system failure. And to make routine service more convenient, it features an additional access port.

Features & Benefits

  • Improved Design: This Transmission Cooler Line Thermostatic Bypass Valve Is Engineered To Better Resist Common Failure Causes That Can Lead To Transmission Damage On Specified GM Trucks And SUVs
  • Protects Drivetrain: Features A Threaded Cap That Protects The Bore And Seals And Eliminates The OE Snap Ring Design, Which Is Prone To Corrosion That Can Lead To Complete System Failure
  • Direct Replacement: Corrosion-Resistant Machined Aluminum Billet, Designed To Exceed The Performance And Reliability Of The Factory Valve, But Match Its Fit For A Seamless, Longer-Lasting Repair
  • Simpler Service: Features An Additional Access Port To Make Routine Service More Convenient
  • Limited Lifetime Warranty
