Carry the Weight – Transmission Cooler R&D, Part 2: Design

Simplicity is often the key to great engineering. The same can be said about Ford’s F-150. The F-150 is about function over frills and getting the job done. Our 2015+ Ford F-150 transmission cooler will follow the same formula. Our focus will be on one key aspect: use as much of the space behind the F-150’s grille as possible. As we saw in our first post, the stock transmission cooler only utilizes about 50% of the available space. To increase that usage to 100% without adding unnecessary complications is where we’ll get the job done, plain and simple.

Ford was kind enough to provide us with convenient mounting points on either end of the radiator and a hard pipe to connect the outlet port on the transmission cooler to the soft line going to the radiator. Our cooler needed another hard line to travel the additional distance from the original soft line to our end tank but compared to some of our recent transmission cooler project, that was be a simple task. To continue with the theme of simplicity, our cooler will be fastened to the radiator by a straightforward set of L-brackets.

We still need to decide whether the core will be a tube-and-fin style or bar-and-plate style, but before anything else can happen, we need to make a prototype. Before we can build a prototype, we need a 3D model to base it on.

With that 3D model complete, we could 3D print our end tanks, waterjet the brackets, and weld together a mock core. The uncomplicated design of each component meant that all these processes were completed quicker than normal and our prototype was ready for a test fit. We removed the stock transmission cooler and mount, assembled our prototype cooler, and bolted it on. Our prototype was almost twice the length and height of the stock cooler, so we were excited to see how it would fit behind the grille of the F-150.

Now that we know our design fits, it’s time to build it out of aluminum and steel. In our next post, we’ll be looking at our production sample and preparing to test how twice the size translates into cooling. Keep an eye out for the next update and feel free to let us know what you think in the comments!

    1. Hi Isaac,

      We’re still in the development phase of this project; but once it’s ready for sale, we’ll have a pre-sale with discounted pricing. Feel free to sign up for our newsletter to be alerted when the pre-sale is live! You’ll only get promotions for your specific vehicle too.


  1. You may have thought about it or not but, the F-350 6.0 Diesel trans cooler is massive and fits up there..
    I had the “HD Cooler” on my 15 F-150 and though it was ok it wasn’t good enough. With the 6.0 cooler I can now haul my Jeep up highway 6 heading to Moab and never see temps over 210. Before I had to back out of it as it would hit 250 easy.
