Description
If you tow, haul, drive in hot weather, or use your Duramax for daily work, keeping transmission temperatures under control can make a big difference in how your truck feels and performs. This Fluidyne Allison 1000 High Performance Transmission Fluid Cooler is built for GM 6.6L LML Duramax trucks and gives your transmission more cooling capacity than the factory setup, helping reduce heat buildup under load. 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 cooler while maintaining minimal pressure drop. Fully welded internal splitter plates help prevent fluid contamination between the hot and cold sides for added durability and reliability. This direct bolt-in replacement uses the existing factory mounting locations for an easier, cleaner installation. Finished with a silver powder coat and proprietary heat-wicking compound, it is designed to handle demanding use while helping your Allison 1000 transmission stay cooler and more consistent.
