If you tow heavy, spend time in hot weather, or use your truck for demanding daily work, keeping transmission temperatures under control becomes a lot more important. This Fluidyne High Performance Transmission Fluid Cooler is designed to give your GM 6.6L Duramax significantly more cooling capacity than the factory setup, helping your transmission stay cooler and more consistent under load. With over 4 times the heat exchanging capacity of the stock cooler, it helps reduce heat buildup during towing, hauling, and long drives.

Built specifically for Chevy and GMC 2500HD and 3500HD trucks equipped with the 6.6L Duramax and Allison 1000 transmission, this direct bolt-in replacement installs at the factory mounting locations for a cleaner, easier installation process. The aerospace-grade aluminum bar plate construction, proprietary fin design, and extremely dense fins-per-inch layout maximize cooling performance while maintaining minimal pressure drop. Fully welded internal splitter plates help prevent contamination between hot- and cold-side fluids, improving durability and long-term reliability.

Finished in a durable silver powder coat with a proprietary heat-wicking compound, this dual-pass transmission cooler is built to handle demanding conditions while maintaining reliable performance. Featuring -10 AN female O-ring fittings, it’s a strong upgrade for Duramax owners looking for better cooling performance and added transmission protection.

Pretty shoe but unrealistic
Size: 10, Color: Caramel
Super high and no actual support. The straps do not hold you in. There was no stability. I had to return.
