Mishimoto Transmission Cooler 18-23 Jeep Wrangler JL/Gladiator JT
If you’ve ever driven your Jeep on a long trip, pulled a trailer, or spent time off-road, you’ve probably noticed how heat can build up in the transmission. The 8-speed ZF transmission is strong and capable, but the factory cooler can struggle due to limited airflow and tight space in the cooling stack. This Mishimoto Performance Transmission Cooler is designed to fix that by improving how efficiently heat is pulled away from your transmission fluid, helping your Jeep stay more consistent and reliable in real-world driving.
This cooler is built to make a noticeable difference where it counts. It increases fluid capacity by 83%, adds 93% more external tube area, and boosts internal cooling surface area by 195% thanks to fins inside the tubes. In simple terms, that means your transmission fluid has more space and more contact with cooling surfaces, so heat is removed faster, even when airflow is low. The tube-and-fin design balances cooling and flow, so you’re not sacrificing performance to gain temperature control. You’ll feel the benefit through more stable shifting, better performance under load, and less stress on your transmission over time.
Designed as a direct fit, this kit keeps installation straightforward with included aluminum spacers and mounting hardware. It’s a solid weekend project for most owners and doesn’t require complicated modifications!
