Description
Excessive heat is a major factor in transmission failure, leading to a shortened lifespan and costly repairs. Unfortunately, OEM transmission coolers often lack the efficiency needed to manage heat effectively, especially under heavy use. To safeguard your transmission and prolong its life, upgrading to a more advanced cooling system is essential.
The Fluidyne High Performance Bar and Plate Transmission Fluid Cooler, designed specifically for the 2020-2024 GM 6.6L L5P Duramax, offers a significant upgrade with four times the heat dissipation capacity of factory models. This ensures your transmission stays cooler and operates more efficiently, even in the most demanding conditions.
Featuring the densest fin count per inch available on the market, the Fluidyne cooler delivers superior cooling performance. Its fully welded internal splitter plates prevent cross-contamination between hot and cold fluid streams, maintaining the effectiveness and purity of your transmission fluid. Constructed from aerospace-grade aluminum with a bar and plate design, this cooler maximizes heat exchange while minimizing pressure drop.
Designed for direct bolt-in replacement, the cooler uses your existing factory mounts for a hassle-free installation. It’s finished with a proprietary heat-wicking powder coat that further enhances thermal efficiency. Backed by a limited lifetime warranty, the Fluidyne High Performance Cooler ensures reliable, long-lasting performance for your 2020-2024 L5P Duramax.
Key Features:
- Over four times the heat dissipation capacity compared to stock coolers
- Direct bolt-in replacement for easy installation
- Maximum fin density for superior cooling
- Fully welded internal splitter plates to prevent fluid contamination
- Tested up to 250 PSI against leaks and ensure optimal performance.
- Aerospace-grade aluminum with bar and plate construction for optimal durability
- Proprietary fin design for enhanced thermal performance
- Powder-coated with a specialized heat-wicking compound
- Limited lifetime warranty for peace of mind
