transmission cooling upgrade
At The Auto Builder, we’re always on the lookout for products made by real enthusiasts—folks who don’t just sell parts, they live them. That’s why we like the team at DIESELSITE. They don’t just talk the talk—they walk the walk. These guys live and breathe diesel, and they know firsthand the problems truck owners face. They take a hard look at factory OEM designs and make them better. Period.
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. That’s where DIESELSITE steps in with a battle-ready solution: the 40-Row Transmission Cooler.
