Recommended Transmission Cooler for 2019 Ford F-150 3.5 EcoBoost with 10 Speed

Updated 07/07/2020 | Published 07/04/2020

Question:

I have a 2019 F-150 3.5L ecoboost with the 10 speed transmission. I have the heavy tow package which brings the towing capacity to the 13,200lbs. I currently have the factory transmission cooler and it isn’t enough for my trailer. My transmission heats up fairly quickly on hills and I have to stop to let it cool down. What larger transmission cooler do you recommend. Many of them say not to use it with the 10 Speed transmission. So I am confused and need the proper direction to help my issue.

The Derale Series 9000 Plate-Fin Transmission Cooler Kit part # D13614 is my recommendation if you want to increase the cooling capacity of the transmission on a 2019 Ford F-150. I can't speak specifically of the 10-speed transmission but so long as the cooler is installed correctly and you add more fluid to the system I see no reason why this could not be done. That said, if you continue to overheat the transmission while towing then you'd be replacing it soon anyway so additional cooling capacity is a must.
