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.

Thermal bypass GMC sierra 2017 is a must.

Easy piece to change. My transmission temperature is between 135F and 150F.

No more 190F. Car is happy.

Needed asap!!

The transmission temperature is no longer reaching 210! The difference is huge I’m on a constant 130-140 degrees no matter what even during hot days in traffic definitely needed if you want a long lasting transmission.

Definitely worth the money to save your transmission from heat.

Such a great upgrade to my 2017 silverado brings down my transmission temps to 140 when it used to be on the high 190 definitely a good investment!!
