Heat is the enemy of automatic transmissions, and towing, crawling and bigger tires all raise fluid temperatures. Wrangler JL, JK and TJ and Gladiator JT owners add a fluid cooler to help keep temperatures steady under heavy use.
This category includes Mishimoto transmission cooler kits and performance coolers, CSF Radiators high-performance transmission coolers and related parts such as an AEV intercooler shroud kit for diesel engines. Kits typically include the cooler, lines and mounting hardware, but contents vary, so check each listing. Coolers are built for specific transmissions and engines, so confirm your setup before ordering, and recheck fluid level after the install.
