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.

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.

Good product

Installed this a few days ago on my 17 chevy with the 8l90. I live up in the cold and on a 15-20 degree day i was running about 99-105 degrees and on a 45-50 degree day it was 110-125. Does the job i needed it too and being in a cold climate it dosent keep the transmission to cold for my liking

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

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.
