The Mishimoto Transmission Coolers for 2006-2010 Chevrolet and GMC 6.6L Duramax LBZ/LMM trucks are engineered to improve transmission cooling for Allison-equipped heavy-duty applications. Built with stacked-plate construction for maximum durability and superior cooling, this direct-fit transmission cooler is ideal for towing, hauling, and demanding diesel truck use. With 84% greater core volume and 125% greater external fin surface area over the stock cooler, it helps manage transmission heat while CNC-machined adapters make it easy to connect to stock fluid lines or AN lines.
