If you use your Duramax for towing, hauling, long road trips, or daily driving in warmer temperatures, transmission heat can become a bigger issue than most people expect. This Fluidyne Allison 1000 High Performance Transmission Fluid Cooler is designed to give GM 6.6L LB7 and LLY Duramax trucks a major increase in cooling capacity over the factory cooler, helping your Allison transmission stay cooler and more consistent under heavy use.

Built with aerospace-grade aluminum bar plate construction and a proprietary high-efficiency fin design, this dual-pass cooler delivers over 4 times the heat exchanging capacity compared to the stock transmission cooler while maintaining minimal pressure drop. The dense fins-per-inch layout improves cooling efficiency, while fully welded internal splitter plates help prevent contamination between hot and cold side fluids for added long-term durability and reliability.

This cooler is designed as a direct bolt-in replacement using the factory mounting locations for a cleaner and easier installation process. Finished in a durable silver powder coat with a proprietary heat-wicking compound, it is built to handle demanding towing conditions, heavy workloads, and everyday driving while helping protect your Allison 1000 transmission from excessive heat.
