Duramax Transmission Fluid Thermal Bypass Valve

Add another measure of protection and increase fluid flow with the easy-to-install billet aluminum PPE Transmission Fluid Thermal Bypass Valve for the GM L5P Duramax Diesel.

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 mechanical valve which maximizes fluid flow from the transmission cooler.

Duramax Transmission Fluid Thermal Bypass Valve, 2017-2019 GM 6.6L

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

Awesome!

I bought this because my 2018 GMC Sierra with 8L90 transmission kept overheating and left me stranded. Come to find out the OEM bypass valve was clogged with debris and never really kept the transmission cool to begin with. When I was towing I used to see temps around 220. Now towing I never get above 190. Definitely recommend!

6L80 bypass

The part is made extremely nice. Fits perfect. Trans was running 190-195, now it runs 160-162. Highly recommend to prolong the life of the grenade known as the 6L80.

Works

Works Great Trans Temp here in Phoenix During the day Usually Hover around 195-205 installed This Bypass Valve Now I’m Seeing around 160-170. Heading to South Dakota in 2 weeks Pulling a Trailer that Should give it a Good Test. Other wise it’s doing what it’s supposed to do and the Build quality is Great.
