Description

Excessive heat is a major threat to your transmission’s longevity, leading to premature wear, reduced performance, and costly repairs. OEM transmission coolers often struggle to provide adequate heat dissipation, especially under demanding conditions, which can leave your transmission vulnerable. Upgrading to a more efficient cooling solution is essential to protect your transmission and enhance its durability.

The Fluidyne High Performance Bar and Plate Transmission Fluid Cooler is designed specifically for the 2011-2014 GM 6.6L Duramax, offering a significant upgrade over stock coolers. With four times the heat dissipation capacity of factory models, this cooler ensures that your transmission runs cooler and more efficiently, even in the most demanding situations.

Engineered with the densest fins per inch on the market, the Fluidyne cooler delivers exceptional cooling performance. Its fully welded internal splitter plates prevent contamination between hot and cold fluids, maintaining the integrity and effectiveness of your transmission fluid. Constructed from aerospace-grade aluminum with bar and plate technology, this cooler provides maximum heat exchange with minimal pressure drop.

Designed as a direct bolt-in replacement, the Fluidyne cooler uses your existing factory mounts for a straightforward installation. Finished with a proprietary heat-wicking powder coat, it further enhances thermal efficiency. Backed by a limited lifetime warranty, the Fluidyne High Performance Cooler ensures long-lasting reliability and superior performance for your vehicle.

Key Features:

  • 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 construction with bar and plate design
  • Proprietary fin design for enhanced thermal performance
  • Powder-coated with a specialized heat-wicking compound
  • Limited lifetime warranty for added peace of mind
