Mishimoto's transmission cooler for 1999–2003 Ford 7.3L Powerstroke is a 37-row stacked-plate design that increases core surface area and fluid capacity to improve cooling over the stock 9-row units. The larger cooler raises core volume roughly 265% and adds about 1.0 qt. capacity, delivering a proven 10+°F drop in transmission fluid temperature with no additional fluid pressure drop and no modifications required for installation.
