Mishimoto's transmission cooler for 2018+ Jeep Wrangler JL improves cooling capacity for the ZF 8-speed by increasing external tube and fin area and fluid capacity over the stock cooler. The design adds internal fins to boost surface contact and heat transfer, increasing fluid capacity to help protect the transmission during low-airflow or demanding driving. It also carries Mishimoto’s Lifetime Warranty.
