GM 6L90 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 6L80/6L90 6-Speed transmission.

The OEM part has restrictive internal passages. When the OEM valve fails in the open 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 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 easily accessed to remove particles from the system. The factory bypass valve does not have this feature.

PPE Compound Washer (114052004) is a compatible replacement for OEM seal (85628205). Two compound washers are required for proper sealing.

Very quick and easy

Very quick and easy install!!

PPE Transmission TBV Bypass , perfectly engineered

Cooler Bypass perfect engineering , quik install , trans temps dropped 40 degrees , going to order the HD Trans cooler , perfect combination , Trans overheat issues over !

Thermal Bypass Valve

10 minute install. Great result as my fluid temps are 30 to 40 degrees lower under towing conditions. Always under 175 degrees. Ambient air temps were 85 degrees. I don’t know how the winter temps will record but we will keep monitoring. I would recommend this for anyone who is towing.

works great

direct fit , runs 40 degrees cooler

Good product

Quality part. Recommend including GM o-rings with product. Re-using factory o-rings can be done, but is not a recommended practice.

Awesome device! Easy install. Get one, you’ll be glad you did!

This is a great device, it lowered my transmission operating temperature by 30°. It was super easy to install. Get one, your transmission will thank you for it!
