Dorman 624-650 Transmission Oil Cooler Bypass Valve
Skip to product information
Transmission Oil Cooler Bypass Valve
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 (Chevrolet TSB 21-NA-199). 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 includes an additional access port.

Do you offer quantity discounts?

Your prices are so good, is it new?
Yes. This item is new and in its original Dorman packaging unless the description above says otherwise.
OEM or aftermarket?
An OEM part is made by, or for, the company that built the vehicle and carries their branding. An aftermarket part is made by another manufacturer to fit the same application, usually for less. Quality runs from below OEM to above it depending on the brand, so the name on the box matters more than the label.
