Eliminate Heat Problems Before They Destroy Your Transmission

If you're putting your RAM 2500 or 3500 to work, whether you're towing, daily driving, or just enjoying your Cummins the way it was meant to be, your transmission deserves better protection than what the factory gave you. The ATS 310-005-2464 Thermal Bypass Valve Upgrade is the kind of simple, smart investment that can save your transmission from early failure. Unlike the stock setup that waits for high temperatures before routing fluid through the cooler, this billet aluminum upgrade sends 100 percent of the fluid through the cooler all the time. That means cooler temps, better performance, and peace of mind on every trip. It also replaces the flimsy factory plastic coupler with a billet filter coupler that won’t leak or crack under pressure. You don’t need custom tuning or special tools to install it, making it one of the easiest and most worthwhile upgrades you can bolt on. If you're serious about protecting your transmission, this is the upgrade that makes it happen.

Designed For Consistent Flow And Maximum Cooling Efficiency

The ATS 310-005-2464 Thermal Bypass Valve Upgrade is engineered to permanently correct one of the most common weak points in late-model RAM 6.7L Cummins trucks, the restrictive thermal bypass valve. This high-performance billet unit is CNC-machined for precision and durability, and it guarantees full-time fluid flow through the transmission cooler regardless of temperature. That consistent flow keeps your transmission fluid running cooler, especially under demanding conditions like towing or hauling. The kit is compatible with both 68RFE and Aisin AS69RC transmissions and comes with a billet filter coupler to replace the factory’s problematic plastic connection. Designed for easy installation, it requires no tuning, special tools, or programming, making it an ideal upgrade for both professional and DIY mechanics. This component not only enhances cooling performance but also extends transmission life by reducing fluid breakdown and internal wear. Built in the USA and backed by a lifetime warranty, it’s a serious solution for anyone who values performance and reliability.
