Anyone who has spent time pulling a trailer through the mountains, sitting in summer traffic, or making repeated long drives in a Duramax knows how quickly transmission temperatures can creep up. The factory cooler works fine for normal driving, but once the truck starts working harder, extra cooling capacity can make a noticeable difference in long-term reliability and consistent performance. This Fluidyne Allison 1000 High Performance Transmission Fluid Cooler is designed to give GM 6.6L LBZ and LMM Duramax trucks a much larger and more efficient cooling solution than stock.

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 keeping pressure drop low. Fully welded internal splitter plates help prevent contamination between hot and cold side fluids, adding durability and long-term reliability.

This dual-pass cooler is a direct bolt-in replacement that uses the existing factory mounting locations for easier installation. Finished in a silver powder coat with a proprietary heat-wicking compound, it is built to handle demanding driving conditions while giving your Allison 1000 transmission a stronger, more reliable cooling upgrade.
