Mishimoto 1999-2003 Ford 7.3L Powerstroke Transmission Cooler

This Mishimoto performance cooler is a direct-fit upgrade for 1999-2003 Ford applications covering Excursion Eddie Bauer, Excursion Limited, Excursion XLT, F-250 Super Duty, F-350 Super Duty. It replaces the weak points of the stock part with stronger materials and better flow or cooling so heat, boost and abuse stay under control on street and track duty. AutoTalent lists verified US-market fitment in the table below.

Why upgrade

Heavy loads are no match for a 1999-2003 7.3L Powerstroke equipped with the Mishimoto 7.3L Transmission Cooler. The stock 7.3L Powerstrock transmission cooler can come up short of providing sufficient cooling, and with more weight in the truck bed, transmission temperatures tend to rise. Mishimoto engineers these kits around real chassis packaging, so hoses, coolers and adapters line up without fabrication on the listed years. Follow the published torque specs and install guide, reuse sensors where instructed, and confirm clearances if you run other supporting mods. Every unit ships with the Mishimoto Lifetime Warranty for as long as you own it.
