KEEPING ALLISON COOL

Mishimoto Trans Cooler, ’01-14 Duramax

After a year of research and development with the goal of creating one cooler that would fit and fix all GM Duramax model issues (sans L5P), Mishimoto finally pulled it off. This new cooler is 170% larger than the early transmission cooler, and more than 40% larger than the largest core offered on late-model Duramax trucks. The use of special CNC’D adapters allows for use of the factory push-connect fittings, or -AN fitting should you choose. In addition, a full bolt-on design using existing holes makes this new cooler a musthave, simple-to-install item that will keep your transmission running much cooler than stock.
