Keep fluid temperatures down and extend the life of your transmission when you add the Mishimoto MMTC-F2D-17SL Transmission Cooler Kit to your Ford 6.7L Powerstroke. The Transmission Cooler Kit utilizes a tube-and-fin design that delivers improved core volume, fluid capacity, and greater fin surface area than the factory cooler. Mishimoto constructs the Transmission Cooler from quality materials and has engineered it for a long service life.
