Mishimoto 10R80 Transmission Thermal Bypass Upgrade F-150 Raptor 2017-2023

When bypass valves on your Raptor's transmission fail, the result can be disastrous. This Mishimoto thermal bypass valve kit prevents damage to your 10R80 transmission and effectively eliminates the risk of overheating due to stock bypass valve failure.

Features and Benefits:
- Direct-Fit for Ford Raptor 3.5L EcoBoost 2017-2023
- Fast warm-up in cold climates and thermostat bypass for constant cooling in warm climates
- Durable CNC-machined billet-aluminum design
- Helps extend transmission life and prevent overheating
- Fits with stock transmission cooler piping, requiring no modification for installation
- Machined cooling fins for added heat dissipation

One major weak point of the 10R80 is the factory-equipped thermal bypass valve. This valve controls transmission fluid flow to the external cooler, and failures are beginning to occur. In these cases, the factory valve is malfunctioning by restricting or eliminating flow to the external cooler, which results in high fluid temps, damaged transmissions, and warnings on your dashboard.

To protect your truck from potential transmission damage, Mishimoto developed a direct-fit thermostatic bypass valve kit for your 2017+ Ford Raptor. The Mishimoto thermal bypass valve kit includes an all-aluminum CNC-machined housing that replaces the stock unit.

This thermal bypass unit includes a fully serviceable 160F thermostat, providing optimal fluid temperatures for all driving conditions. For those in warm climates or vehicles being used in extreme driving/towing conditions, this kit also includes a bypass assembly that provides full flow to the transmission cooler, regardless of temperature.
