The DmaxStore SubZero High Flow Allison Transmission Cooler is purpose built to keep your stock or built transmission running cooler than ever before. With a 483% larger oil capacity than the stock cooler, your transmission will stay cool. If your transmission temperatures are starting to creep up, this is the best way to fix the problem. The DmaxStore SubZero High Flow Transmission Cooler is much bigger than the stock unit. It is 120% thicker and 12% taller. The DmaxStore cooler is a much heavier duty unit than the stock one providing increased cooling efficiency. Not only will this cool better but it will last longer. Featuring a heavy duty aluminum exterior to prevent corrosion and cracking, you will be able to run this cooler on your truck for many miles without issue. The SubZero Cooler is the biggest transmission cooler that fits into the factory position, by utilizing the factory mounts. It takes advantage of the stock lines resulting in a lower chance for leaking while maintaining the OEM fit and finish.
