Description
If you tow, haul, or use your Duramax as a daily workhorse, keeping transmission temperatures under control can make a big difference in how your truck performs and holds up over time. This Fluidyne Allison 1000 High Performance Transmission Fluid Cooler is designed for GM 6.6L L5P Duramax trucks, giving you a serious cooling upgrade over the factory cooler. Built with aerospace-grade aluminum bar plate construction, a proprietary fin design, and one of the densest fins-per-inch layouts available, this cooler delivers over 4 times the heat exchanging capacity compared to the stock unit while maintaining minimal pressure drop. Fully welded internal splitter plates help prevent fluid contamination between hot and cold side fluids, improving durability and long-term reliability. This direct bolt-in replacement uses the factory mounting locations for an easier installation and cleaner fit. Finished with a durable powder coat and proprietary heat-wicking compound, it is built to handle towing, hauling, hot weather, and demanding driving conditions with confidence.
