The Mishimoto Transmission Coolers for 2015-2016 Chevrolet and GMC 6.6L Duramax LML trucks are designed to improve transmission cooling performance for Allison-equipped heavy-duty diesel applications. Built with durable stacked-plate construction, this direct-fit transmission cooler provides superior heat management for towing, hauling, and demanding driving conditions. With 67% greater core volume and 164% greater external fin surface area over the stock cooler, it helps reduce transmission temperatures while CNC-machined adapters make connection to stock fluid lines or AN lines simple and secure.
