Description
The Mishimoto 2017+ Ford Raptor 10R80 Thermal Bypass Valve Kit is designed to improve the cooling efficiency and reliability of your truck’s transmission system. Specifically engineered for the 2017-2020 Ford F-150 Raptor equipped with the 10R80 transmission, this kit addresses a common failure point—the factory thermal bypass valve—that can restrict fluid flow to the external cooler, leading to overheating and potential transmission damage. Constructed from durable CNC-machined billet aluminum, this direct-fit replacement housing ensures a precise and secure installation that maintains optimal fluid management under all driving conditions. The included fully serviceable 160°F thermostat allows for rapid warm-up in cold climates and effective cooling in hot environments, contributing to extended transmission lifespan and consistent performance. For vehicles subjected to extreme conditions or in warm climates, the bypass assembly can be modified to provide full flow regardless of temperature, further enhancing cooling capabilities. Easy to install in about one hour, this kit is an essential upgrade for maintaining transmission health and preventing costly failures. As with all Mishimoto products, it comes with a lifetime warranty for added peace of mind.
