6L80 Transmission Fluid Thermal Bypass Valve

Add another measure of protection and increase fluid flow to transmission cooler. Increase cooling capacity with this easy-to-install billet aluminum PPE Transmission Fluid Thermal Bypass Valve for the GM 6L80 6-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 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.

Big Change

2020 Chevy Silverado 1500 5.3 RST. Notice a huge difference in temps and transmission operations. I bought this because I wanted to prolong my transmission, and what better way to do that? So I ordered it, and it was shipped / delivered fast. I definitely will be ordering the big cooler next.

Works as advertised!

This is a beautifully functioning improvement that gives one a piece of mind when it comes to avoiding a potential catastrophic transmission failure due to overheating. Quick installation and 30* drop in operational temperature. I highly recommended this upgrade.

Thermal bypass valve 8l90 transmission

Works as described. Temperature of fluid stays below 160 degrees. Just what the doctor ordered

Dropped 60 degrees F

Installed this product at the same time I installed the PPE transmission pan. I love being able to check my transmission fluid without waiting for the thermostat to open. Even better yet I drop 60° on my trans temp. I highly recommend this product.
