Push Your Powerstroke Further—Without the Heat Risk
When you're pushing the limits of your 7.3L or 6.0L Powerstroke Diesel—whether you're running big power or hauling heavy—you’re playing a high-stakes game with your transmission. Heat is your enemy, and stock transmission coolers simply weren’t designed for the kind of loads serious truck owners demand.

Designed to Dominate Heat
Unlike other aftermarket coolers that top out at 37 rows, DIESELSITE’s 40-row stacked plate design leads the pack in both fluid capacity and heat dissipation. This means more surface area, more cooling power, and more confidence—whether you’re towing up a mountain pass or hammering down the highway with a fully built rig.
Tested up to a jaw-dropping 90,000+ GVW, this cooler absolutely crushes the OEM spec of 28,000 GVW on 1999–2003 7.3L trucks. That’s more than triple the capability. Translation: no more sweating over transmission temps.
Built for Reliability. Backed by R&D.
Every DIESELSITE product is engineered with obsessive attention to detail—and this cooler is no exception. It’s purpose-built for both the 7.3L and 6.0L platforms, with hardware options tailored for each engine. Whether you’re a weekend warrior or daily workhorse, this cooler adds a massive layer of insurance to your build.
Why It Matters
Power means nothing if your transmission can’t keep up. Don’t let overheating sideline your investment. The DIESELSITE 40-Row Transmission Cooler is a must-have upgrade for anyone serious about protecting their drivetrain under pressure.
