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.

Great quality, easy to install

Really nice part. Good quality, no issues so far. Does what it says and keeps my trans temp down around 160 even in Texas heat.

Transmission in my 2016 silverado burned up and had to replace it and even the new one I noticed temps around 200° so after seeing recommendations for this bypass I tried it out, on a 90 degree day im seeing Temps around 180 so definitely helped will probably upgrade the cooler itself as well

Much cooler temps

I’m in Houston Texas, couple trips to the coast I was seeing temps of 215 in my 2019 silverado 1500 with the 8L90. After install, on very hot days the hottest temps I’ve seen in traffic are around 174. But not uncommon to cruise out to San Antonio and see 145-150 degrees the whole way out.

Perfection

Put it on my 2016 gmc sierra. I built the motor a couple years ago and have a 3200 stall converter and my trans would stay hot. Normal days she was around 200-210. Put this in and it stays around 152 while driving and 158 idling. Super easy install and highly recommend. Quality on it is outstanding, couldn’t be anymore satisfied with this product.

Works great. Transmission runs cooler. I highly recommend PPE not only for their parts but for their service.
I first reviewed this at a 3 because I thought the service plug was a drain plug. And when installed the plug was on top. Within 30-45 minutes of the review and before I could call PPE a representative called to resolve my issue. I will definitely be using PPE in the future.
