Excessive heat is a primary cause of transmission failure, leading to reduced lifespan and expensive repairs. Unfortunately, OEM transmission coolers often lack the efficiency needed to manage heat effectively, especially under demanding conditions. To protect your transmission and extend its life, upgrading to a more efficient cooling system is crucial.

The Fluidyne High Performance Bar and Plate Transmission Fluid Cooler, designed for the 2017-2019 GM 6.6L L5P Duramax, is engineered to deliver four times the heat dissipation of factory models. This ensures that your transmission operates at cooler, more efficient temperatures, even under the most challenging conditions.

With the highest fin density per inch available on the market, the Fluidyne cooler provides unparalleled cooling performance. Fully welded internal splitter plates prevent cross-contamination between hot and cold fluid streams, preserving the integrity of your transmission fluid. Crafted from aerospace-grade aluminum with a bar and plate design, this cooler maximizes heat exchange while minimizing pressure drop.

This cooler is a direct bolt-in replacement, using existing factory mounts for an easy and straightforward installation. It’s also finished with a proprietary heat-wicking powder coat that enhances thermal efficiency. Backed by a limited lifetime warranty, the Fluidyne High Performance Cooler offers reliable, long-lasting performance for your 2017-2019 L5P Duramax.
