68RFE Thermal Bypass Valves

The stock thermostatic valve on the factory 68RFE is a known failure point that can actually cause your truck and transmission some serious problems. Our selection of 68RFE thermal bypass valves improve your transmission's reliability and are small, hassle-free upgrades that can save you some massive headaches. The stock thermostatic valve is known for getting stuck closed, which can stop fluid flow into your transmission cooler. Aftermarket 68RFE thermal bypass valves remove the thermostat element entirely and keep fluid flowing into the transmission cooler at all times. The end result is lower transmission operating temperatures and the elimination of a known point of failure that can kill your transmission. All of these 68RFE bypass valves are extremely easy to install, and drop right into place of the stock valve in minutes.
