If you're pushing your 2006-2010 Chevrolet or GMC truck with the 6.6L Duramax engine hard, whether it's for towing, hauling, or just everyday driving, keeping your transmission cool is crucial. Heat is the biggest enemy of a transmission, and Mishimoto has developed a direct-fit transmission cooler specifically for these trucks to combat that. This cooler is designed to handle the demands of your Duramax, ensuring your transmission stays within optimal operating temperatures.

This Mishimoto transmission cooler features a robust stacked-plate construction, which offers both increased durability and powerful cooling capabilities. Compared to the stock unit, this cooler boasts an impressive 84-percent greater core volume and a 125-percent larger fin surface area.

The kit includes CNC-machined adapters that connect directly to your truck's stock transmission cooler lines, making for a leak-free installation. Direct-fit brackets and custom-fit hoses are also included, simplifying the installation process considerably.

This transmission cooler is a solid option for a wide range of Chevrolet and GMC trucks, including models like the Silverado 2500 HD, Silverado 3500 HD, Sierra 2500 HD, and Sierra 3500 HD. Mishimoto backs this transmission cooler with their Lifetime Warranty, which includes Accident Protection, giving you peace of mind for as long as you own your truck.
