The Derale 20561 is a direct-fit remote transmission cooler kit built for the Jeep Wrangler TJ and YJ. It pairs an efficient plate and fin cooler with an 8-inch thermostatically controlled Tornado fan, so the transmission stays cool even at low speeds and in off-road situations where natural airflow is limited. The assembly mounts to the frame rail with no drilling and rotates nearly 90 degrees, so it can sit vertically for street driving or tuck horizontally out of the way off-road. Derale states the kit reduces transmission fluid temperatures by 30 to 40 degrees F.
