The Mishimoto transmission cooler for the 2006-2010 Chevrolet/GMC 6.6L Duramax LBZ/LMM is a direct-fit, stacked-plate upgrade that lowers fluid temperatures for towing, fleet, and daily-driven trucks running the Allison 1000 transmission. Its 13-row core delivers 84% greater core volume and 125% greater fin surface area than the stock cooler, and CNC-machined adapters connect to the factory lines (or AN lines) for leak-free flow with direct-fit brackets and tailor-made hoses.
