Product Description
Our 2015-2018 RAM 6.7L Cummins transmission cooler utilizes a tube-and-fin core with internal fins to balance flow with efficient cooling. With a massive 112% greater core volume, 237% increase in fin area, and 226% increase in fluid capacity, this trans cooler is a huge improvement over the stock unit. To make even better use of that extra core volume, the Mishimoto transmission cooler utilizes fins within the tubes to not only add more cooling surface area, but also ensure more of the fluid contacts the tube, leading to better cooling efficiency. All these improvements make the Mishimoto transmission cooler the ideal replacement for your stock transmission cooler.
Installation of the Mishimoto 2015-2018 RAM 6.7L Cummins transmission cooler requires no cutting or other modifications and includes all hardware needed for a fast and easy install. Like all Mishimoto products, this transmission cooler is backed up by our Lifetime Warranty with Accident Protection for worry free cooling as long as you own it.

When we last saw our 2015-2018 RAM 6.7L Cummins performance transmission cooler, it was an aluminum box with 3D prints for ports. In this post, however, we'll be taking that box and turning it into a fully functional transmission cooler. But first, we need to recap how we got here and perform one more test.
In our last post, we finalized our design for our 2015-2018 RAM Cummins transmission cooler. Our performance cooler will use a tube-and-fin core like the stock unit, but to add cooling capacity, we'll be making our core 60% thicker than stock with a 112% larger core volume. We'll be improving the internal structure of the cooler by adding fins to the inside of the fluid tubes. These fins make the cooler more efficient by adding
One of our favorite parts of the R&D process is the design and prototyping phase. It's our first chance to see our products come to life and compare them to the stock parts. In our last post, we looked at the stock transmission cooler for the 2015-2018 RAM 6.7L Cummins. We learned that, compared to the 2003-2009 6.7L Cummins transmission cooler, the stock 2005-2018 transmission cooler is relatively simple. Two cylindrical end tanks connect the tube-and-fin core, and four mounting tabs secure the cooler to the radiator. The transmission lines connect to the cooler with two standard quick-disconnects.
If you ask most drivers what the heart of their vehicle is, they'll likely say the engine. The engine provides power and is often the most advertised part of the powertrain, but it's not alone. In fact, if you ask somebody who tows heavy loads, they might say the heart of their car or truck is the transmission. A vehicle's transmission is responsible for delivering all the power the engine makes to the wheels, and its success or failure in that role can make or break the vehicle, especially when towing. Few drivers know the importance of a well-designed transmission better than owners of 6.7L Cummins-powered RAM trucks and the engineers at Mishimoto.
We also know that it doesn't matter how well-designed a transmission is if you can't keep it cool. Over the years, we've developed transmission coolers for nearly every iteration of Cummins-powered RAM; now, it's time to apply that experience to one of the latest generations with a performance transmission cooler for the 2015-2018 6.7L
