If you’ve got a 2019 or newer Dodge Ram with the Cummins 6.7L diesel, this thermal bypass valve upgrade is a smart move for your transmission’s health. The stock bypass valve can fail over time, leading to overheating and accelerated wear—especially if you tow or drive hard. This kit replaces it with a heavy-duty billet aluminum valve that’s way more durable. It’s designed to optimize cooling in both hot and cold conditions, so your transmission warms up properly when it’s chilly but doesn’t overheat when it’s scorching out. The kit includes the thermal bypass valve itself, a billet filter coupler, and a cooler block clamp plate. It fits trucks with either the 68RFE or Aisin AS69RC transmission. Installation is straightforward if you’re mechanically inclined, but you might want a pro to handle it if you’re not comfortable with transmission lines. By preventing bypass failure, you’ll extend the life of your transmission fluid and components, saving you from costly repairs down the road. Perfect for diesel enthusiasts, heavy haulers, or anyone who wants extra reliability. A simple upgrade that offers big peace of mind. Just make sure your truck’s year and transmission type match before ordering!
