Description

Excessive heat is one of the leading causes of transmission failure, shortening its lifespan and leading to costly repairs. OEM transmission coolers often fail to provide sufficient heat dissipation, especially in demanding conditions, leaving your transmission vulnerable to overheating. For those looking to protect their investment and extend the life of their transmission, an upgrade to a more efficient cooling solution is essential.

The Fluidyne High Performance Bar and Plate Transmission Fluid Cooler is the perfect solution for the 2015-2016 GM 6.6L Duramax. Engineered to offer four times the heat dissipation of factory coolers, this advanced cooler ensures your transmission runs cooler and more efficiently, even under the toughest conditions.

Designed with the highest fin density per inch available on the market, the Fluidyne cooler delivers superior cooling performance. Its fully welded internal splitter plates prevent any cross-contamination between hot and cold fluid streams, maintaining the purity and effectiveness of your transmission fluid. Constructed from aerospace-grade aluminum with a bar and plate design, this cooler maximizes cooling capacity while minimizing pressure drop.

This cooler is a direct bolt-in replacement, utilizing your existing factory mounts for a hassle-free installation. It’s also powder-coated with a proprietary heat-wicking compound to enhance thermal efficiency even further. Backed by a limited lifetime warranty, the Fluidyne High Performance Cooler guarantees reliable, long-lasting performance for your vehicle.

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
