The Mishimoto transmission cooler kit for the 2007-2011 Jeep Wrangler JK (3.8L, 42RLE) tackles the high transmission fluid temperatures these Jeeps see off-road and in hot climates. Precision-engineered brackets mount a large 19-row bar-and-plate cooler in the front grille area to maximize airflow and cooling efficiency, reducing fluid temperatures to cut transmission wear. The kit includes all lines and hardware for an easy install and pairs well with the Mishimoto JK oil cooler kit and aluminum radiator.
