Bypass Eliminator for 4R100 Transmission

If you’ve owned a 7.3L Powerstroke long enough, you probably already know the factory transmission cooler bypass setup on the 4R100 isn’t doing you any favors—especially if you tow heavy or live in a hotter climate. The SunCoast Cooler Bypass Eliminator is a simple yet highly effective upgrade that removes the factory bypass tube, allowing full-time fluid flow through the transmission cooler. That means cooler temps, more consistent performance, and better protection for your transmission when it matters most. Whether you’re pulling a trailer, hauling gear, or just trying to extend the life of your transmission, this bypass eliminator gives you one less thing to worry about. It improves fluid circulation by sending all the trans fluid through the cooler rather than bypassing it under certain conditions like the OEM setup does. The result? Lower operating temps and less risk of heat-related wear or failure.
