Description

When it comes to keeping your transmission cool, not all coolers are created equal. Fluidyne’s bar plate design and dual-pass flow maximize heat dissipation, ensuring your trans stays at optimal temps even under extreme loads. More fluid, more cooling, more durability—because heat is the problem, and this is the solution. Excessive heat is one of the most significant factors that can reduce the longevity of your transmission. Over time, high temperatures can lead to premature wear, decreased performance, and costly repairs. Unfortunately, OEM transmission coolers often fall short when it comes to efficient heat dissipation, especially under heavy loads or in high-performance applications. To protect your transmission and extend your lifespan, upgrading your cooling system is essential. Introducing the Fluidyne High Performance Bar and Plate Transmission Fluid Cooler, specifically engineered for the 2006-2010 GM 6.6L Duramax. This advanced cooler delivers four times the heat dissipation of factory models, ensuring your transmission operates at cooler, safer temperatures. Designed with the densest fins per inch available on the market, the Fluidyne cooler provides unmatched cooling performance. Its fully welded internal splitter plates prevent fluid contamination between hot and cold sides, ensuring the purity and effectiveness of your transmission fluid. Constructed from aerospace-grade aluminum using bar and plate technology, this cooler maximizes heat exchange while minimizing pressure drop, offering a perfect balance of efficiency and durability. This cooler is a direct replacement for your factory unit, utilizing existing factory mounts for an easy, hassle-free installation. Finished with a proprietary powder-coated heat-wicking compound, it further enhances heat transfer efficiency. Backed by a limited lifetime warranty, the Fluidyne cooler guarantees long-term reliability and superior performance for your vehicle.
