Mishimoto 2017+ Ford Raptor 10R80 Thermal Bypass Valve Kit

The 10R80 transmission in your 2017-2020 Ford Raptor 3.5L EcoBoost is a strong unit, but like any new design, it can have weak points. A common issue reported with this transmission is the failure of the factory thermal bypass valve. This valve is crucial because it controls how much fluid goes to the external transmission cooler. When it malfunctions, it can restrict or stop fluid flow, leading to high temperatures, potential transmission damage, and dashboard warnings. To help protect your Raptor, Mishimoto has developed a direct-fit thermal bypass valve kit.

This kit replaces the stock valve with a CNC-machined aluminum housing. It features a serviceable 160F thermostat that helps the transmission warm up quickly in cold weather and maintain optimal temperatures. For those in warmer climates or who use their truck for heavy-duty tasks like towing or extreme driving, the kit also includes a bypass assembly that ensures constant flow to the cooler, regardless of temperature. By using this kit, you can help extend the life of your 10R80 transmission and avoid overheating issues caused by a faulty stock valve.

Installation is straightforward, typically taking about an hour. This kit is designed to be a direct replacement for the factory part, making the process easier. The kit comes with the Mishimoto Lifetime Warranty for added peace of mind.
