Whether you're cruising the highway or crawling a trail through Moab in your 2018+ Jeep Wrangler JL, keeping your transmission cool should be a priority.

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.

  • Direct fit for 2018+ Jeep Wrangler JL
  • 83% increase in fluid capacity over stock transmission cooler
  • 93% increase in external tube area over stock transmission cooler
  • 195% increase in internal fin surface area for comprehensive cooling in even the harshest conditions
