Mishimoto Performance Transmission Cooler for 2018-2025 Jeep Wrangler JL & Gladiator JT

Fits select 2018-2025 Jeep Wrangler JL and 2020-2025 Jeep Gladiator JT models.

Whether you are cruising the highway or crawling technical trails in Moab, maintaining stable transmission temperatures is critical for the longevity of the ZF 8-speed transmission. The Mishimoto performance transmission cooler is engineered to overcome the limitations of the cramped factory cooling stack, maximizing thermal efficiency for both on- and off-road applications.

This cooler significantly outperforms the stock unit by expanding the core's dimensions and internal architecture. By increasing the external tube area by 93% and the external fin area by 32%, it captures more ambient airflow through the Jeep's grille. Internally, unique fins within the tubes provide a 195% increase in surface area, ensuring maximum heat transfer as fluid passes through. With an 83% increase in total fluid capacity, your drivetrain remains protected even during low-speed, high-load crawling.
