The Jeep JK is known to experience high transmission fluid temperatures, especially when off-roading or driving in hot climates. Mishimoto has developed an ideal upgrade for reducing temperatures with our direct-fit transmission cooler kit, engineered specifically for the JK chassis. This kit uses precision-engineered brackets to mount a large 19-row cooler in the front grille area, thus maximizing airflow and providing significant increases in cooling efficiency. This kit significantly reduces transmission fluid temperatures, resulting in decreased transmission wear and improved vehicle safety. The Mishimoto Jeep JK Transmission Cooler Kit includes all lines and hardware necessary for an easy installation.
