Product Description
The 8-speed transmission mated to the 2018+ Wrangler JL makes it incredibly capable both on and off-road. But in both situations, the excellent ZF transmission could be let down by the stock transmission cooler. Poor airflow and a cramped cooling stack makes the stock transmission cooler the weak link in your JL's drivetrain, but Mishimoto has the solution.
Mishimoto's performance transmission cooler for the 2018+ Jeep Wrangler JL is custom designed to extract every ounce of cooling capacity from the air passing through your JL's grille. Our transmission cooler features a 93% increase in external tube area and a 32% increase in external fin area to make sure that all of the air passing over the cooler is utilized.
The Mishimoto transmission cooler also features unique fins within the tubes to add even more cooling surface area and make sure that all of the fluid is in contact with a cooling surface. This feature, combined with the 83% increase in fluid capacity, means that no matter how low the airflow is, your transmission will stay safe and cool.
Like all Mishimoto 2018+ Jeep Wrangler JL products, this performance transmission cooler is backed by our Mishimoto Lifetime Warranty, so you'll never have to worry about an overheating transmission ruining your day on the trail or road trip ever again.

Despite its simple appearance, improving upon the stock 2018+ Jeep Wrangler JL transmission cooler will take some clever engineering. In many cases, the solution to extracting more efficiency from a heat exchanger is to make it bigger, but with the cramped cooling stack of the JL, the size of our cooler would be limited.
In our last post, we looked at the stock 2018+ Jeep Wrangler JL transmission cooler and its home in the 2.0L Wrangler. Our performance trans cooler will fit all of the available engines and the 2020+ Gladiator, but the complexity of the 2.0T's cooling stack makes it the perfect R&D vehicle. That complexity also restricts how much we can change the dimensions
When we last saw our 2018+ Jeep Wrangler JL performance transmission cooler, it was nothing more than a box, constructed from aluminum u-channel, with plastic end tanks glued to it. This time, however, we'll be getting our hands on a fully functioning production sample.
In our last post, we began the design process for our performance transmission cooler and created a prototype. Thanks to the JL's cramped cooling stack, our ability to enlarge the transmission cooler was severely limited in the vertical and horizontal planes. However, we were able to significantly increase the thickness of the core from 19mm to 32mm. This 68% increase
Engines get a lot of press these days. Every manufacturer wants to flaunt their latest, most fuel-efficient, technologically advanced, or powerful engine yet. The hype is even more prominent when manufacturers make drastic changes to a long-standing model, like the 2018+ Jeep Wrangler.
When FCA announced the 2018+ Wrangler JL in late 2017, all the journalists were clamoring for headlines on the new 2.0L, turbocharged, mild-hybrid engine. How would the mild hybrid perform offroad? Would the turbo lag make it a dog in stop and go traffic? What about that 24-volt power system? Everybody forgot about the 3.6L Pentastar that's powered the Wrangler, and over 20 other models, for almost a decade. But the 3.6L Pentastar wasn't the only thing forgotten in the fanfare over the new 2.0T.
