Transmission Fluid Thermal Bypass Valve

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 8L90 8-speed transmission.

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 dangerously overheat. 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.

For further protection, a Neodymium magnet-equipped service plug with an 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.

Didn’t fit like the OEM. The transmission lines were very difficult to install and It developed a leak after installing and ruined the transmission on a long road trip.

Good product

Installed this bypass a while ago amd i live up north and on 20-30 degree days it stays around 90-105 degrees and in warmer days it will run around 110-125. Much better than 195.

Easy install

Took about 5 minutes to install you need a 10mm for the plate that holds the trans lines in and the side bolt is a 13mm very simple and easy don't forget to put the old gasket on the new one mine just stayed in place when I pulled mine off so I just stuck the new one up there transmission Temps are in a great range now

Great product

No offices with figment, temps are running lower now. Only issue I had was dealership pinched the rubber washer on the side bolt. Didn’t void my warranty. I had purchased part and the Chevy dealer installed it when they put my new transmission in. 2017 High Country 1500 4x4. 98k miles
