The Mishimoto transmission cooler for 2003–2007 Ford 6.0L Powerstroke upgrades transmission cooling for heavy-load towing and hauling. Its 37-row stacked-plate core increases surface area and raises core volume by 21% while adding roughly one-third quart of fluid capacity, yielding a proven drop in transmission fluid temperature of about 10°F without creating additional pressure drop. The cooler fits stock equipment with no modifications required.
