Transmission Fluid Thermal Bypass Valve (10L80)

Add another measure of protection and increase fluid flow to the transmission cooler. Increase cooling capacity with this easy-to-install billet aluminum PPE Transmission Fluid Thermal Bypass Valve for the GM 10L80 10-Speed transmission.

GM FACTORY BYPASS VALVE

The OEM part has restrictive internal passages. When the OEM valve fails in the closed position, transmission fluid doesn’t reach your cooler. This can be caused by mechanical failure or debris. The result of stock valve failure can cause the transmission to overheat dangerously. Without properly cooled transmission fluid, the demands of towing and rigorous stop-and-go driving conditions shorten the life of transmission components. The PPE Bypass Valve eliminates the extremely restrictive mechanical factory valve, maximizing fluid flow to and from the transmission cooler.

2019-2024 GM 3.0L w/ 10L80 Transmission - Transmission Fluid Thermal Bypass Valve

For further protection, a Neodymium magnet-equipped service plug with O-ring seal has been added. The removable plug traps ferrous debris and can be accessed to remove particles from the system. The factory bypass valve does not have this feature.

Installation Guide:

Transmission Fluid Thermal Bypass Valve - GM 3.0L Duramax 10L80"

Almost works too good

Absolutely does what it says. Lowered my trans temp from an average of 170-180 to 110-120 here in the dead of winter. Should work great in the summer months when towing my camper. Now the negative. After a 750 mile round trip journey with the new lower temps I lost 2-3mpg cruising at interstate speeds. I’m sure this won’t be an issue in the summer. Just felt it should be noted for people in colder climates.

Installed the transmission bypass valve today, resulting in a significant temperature drop from a consistent 190-225°F to 120-145°F. Amazing performance, and thank you for exceeding expectations.

Worth every penny !

Installation on my 2018 Chevy 8L90 was breeze and my transmission is running nice and cool in this Florida weather . I did replace the old gasket seal with a new one . It would be nice to see one (gasket) come with this TBV as a kit to make it that much more complete but overall I am highly satisfied with this product.
Note to the DIY’ers: Be sure to keep up with the small o-ring seals on your trans lines when removing the stock valve . One of mine stayed in the old block hole and I almost missed it.

The thermal bypass paired with the deeper pan, towed 9k from Sacramento to Coos Bay Oregon. I don’t think my transmission ever reached 160. Very very pleased with my purchase from PPE. Cooled my transmission down greatly. And with their upgraded spin on filter, truck is shifting like butter!

DON'T FOR GET TO TIGHTEN THE PLUG

HAVEN'T SEEN A DRAMTIC DIP IN TEMPERATURES AND I WAS A DUMMY AND DIDN'T CHECK THE PLUG BEFORE A TEST DRIVE AND LOST NEARLY A GALLON OF FLUID. OOPS MY BAD BUT AT LEAST THE BOTTOM OF MY SUBURBAN WON'T RUST FOR A WHILE
