Description

This DieselSite Transmission Cooler is designed to mitigate excessive heat in 7.3L and 6.0L Powerstroke transmissions, addressing a primary cause of premature transmission failure, especially under high horsepower or heavy towing conditions. It boasts an estimated 90,000+ GVW rating, a substantial improvement over the stock 1999-2003 7.3L cooler's 28,000 GVW. The cooler features a 40-row stacked plate design, which significantly increases the surface area for efficient heat exchange and enhances fluid volume for improved cooling. The kit includes custom 3/8 inch to 1/2 inch adapter fittings, ensuring compatibility with both 7.3L and 6.0L setups.
