40-Row 7.3L E4OD Transmission Cooler Kit

Performance and Reliability: Can You Have Both?

When it comes to getting the most out of your truck, balancing performance and reliability is crucial. The biggest challenge you face, especially with performance upgrades, is managing heat—an issue that’s particularly significant in transmissions for the 7.3L and 6.0L Ford Powerstroke Diesels.

The Issue with Other Coolers:

Factory transmission coolers are only marginally effective for everyday driving. They struggle to handle increased heat when your truck is under load, such as during towing or when you've added horsepower. The leading cause of premature transmission failure is heat, which is an inevitable side effect when pushing your truck beyond its factory limits.

The DIESELSITE Solution:

DIESELSITE has engineered a top-of-the-line transmission cooler designed to efficiently manage heat and extend the life of your transmission, no matter how much power you produce or how heavy you tow. This cooler is built to handle an estimated 90,000+ GVW, far surpassing the stock coolers on the 1999-2003 7.3L platform, which are rated for just 28,000 GVW.

Design Features:

• - 40-Row Stacked Plate Design: Our cooler features a 40-row stacked plate design, which significantly increases the surface area for heat exchange, ensuring superior cooling performance compared to standard designs.
  
• - Increased Fluid Volume: The larger surface area allows for increased fluid capacity, enhancing cooling efficiency by allowing more heat to dissipate quickly.
  
• - Market-Leading Innovation: While other aftermarket coolers max out at a 37-row design, our commitment to research, development, and rigorous testing has resulted in a cooler that stands out in both performance and reliability.

Hardware Options:

Our transmission cooler is specifically designed and tested for both the 7.3L and 6.0L Ford Powerstroke Diesel applications, complete with the necessary custom adapters or hardware kits tailored to your vehicle's requirements.
