The Mishimoto transmission cooler for the 2015-2017 Ford Mustang GT and V6 (automatic) keeps fluid temperatures in check during hard driving and track time, where the stock cooler can fall behind. Its 20-row stacked-plate core has 50% more surface area and a 180% increase in core volume over the stock 6-row cooler — roughly double the cooling capacity — for a proven 18°F drop in transmission fluid temperature with no added pressure drop. It installs with no modifications.
