The stock 6R140 cooler on a 2017-2019 6.7L Powerstroke Super Duty is liquid-to-liquid, so transmission fluid can only get as cool as engine coolant. Under sustained towing and hot weather that limit shows up fast, and heat is what wears transmissions out.

The Mishimoto MMTC-F2D-17X bypasses the factory cooler and sends fluid through a dedicated air-cooled tube-and-fin aluminum core. Application-specific hard lines are included for a direct-fit install on 2017-2019 Ford F-250/350/450/550 6.7L Powerstroke trucks—no custom plumbing.
