Features & Product Details

Whether you're cruising the highway or crawling a trail through Moab in your 2018+ Jeep Wrangler JL or 2020-22 JT , keeping your transmission cool should be a priority.
The 8-speed transmission mated to the Jeep 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 Jeep 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 Jeep 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.

Mishimoto Transmission Cooler 3.6L 2019 Jeep Wrangler JL 5 months ago

Don L.
Fast Shipping as always. After all the Jeep mods over the last several years with all the extra weight, even with re-gearing my trans fluid in our Texas 100 degree heat would creep up to 230F sometimes and had seen 240 in the Colorado mountains. Some of my mods include Teraflex 4" Alpine CT4 full lift, MetalCloak full steel skids, front & rear bumpers, Warn Winch, bigger tires, rooftop rack and rooftop tent, complete Yeti Steersmarts front steering components, steel steering box, ARB onboard air, KC 12 Rock lights, Amber and white driving lights, 75 quart ARB Frifg/Freezer, 100ah Lithium battery bank, 40amp DC to DC Charger, 500 watt True Sine Inverter, full load of tools for the Jeep including 1/2" impact, big spare tire with 2 extra Rotoloc fuel tanks mounted on it, Teraflex heavy duty tailgate gate to handle the weight, full cooking and camping gear, onboard Gaia navigation on 10.5" tablet and the list of mods goes on and on. You get the idea of all the added weight straining the ZF transmission. We are retired and overland all over the USA. After I installed the Mishimoto Transmission Cooler we tested it and the trans temp never went over 199 F. The Mishimoto Transmission Cooler holds about 1/2 quart more trans fluid and fiscally looks twice as big as the OEM Cooler. I preformed a full trans fluid change at the same time of installing the Mishimoto just because i have 50,000 miles on our Jeep now. Replaced my trans fluid with Amzoil Signature Series trans fluid. I know the outside temp isn't 100 degrees this time of year but the trans temp thru rolling hills and 4x4ing over a full day never exceeded 199. So it sure appeared to cool better than the OEM small Cooler. I like it anyway and seems to cool the trans fluid alot better now. Was it worth the extra expense and time to do this upgrade, I think it was. I didn't think ti take any photos, sorry. Install was easy and as far as replacing the trans fluid and filter goes you can watch a YouTube video on how to perform that.
