Transmission Cooler for 2018 Ford F-150 with 5.0L V8 Engine and Sealed Transmission

Question:

I have a 2018 F150 XLT with a 5.0 engine. What unit would I need that will work. The truck has active fins for airflow and also how would I add transmission fluid when the truck has a sealed transmission after the install? Thanks

In regards to transmission coolers, the best option for your 2018 Ford F-150 with a 5.0L V8 (or any vehicle for that matter) is you want the largest cooler that you can get to fit because you cannot over-cool fluids. So you are going to want to measure at the installation location on your truck (see accompanying diagram) and select the largest cooler that fits.

Your options are:

- Derale Series 8000 Plate-Fin Transmission Cooler Kit # D13504: 11" wide x 12" tall x 7/8" deep
- Derale Series 8000 Plate-Fin Transmission Cooler Kit # D13502: 11" wide x 7-1/4" tall x 7/8" deep
- Derale Series 9000 Plate-Fin Transmission Cooler Kit # D13611: 11" wide x 3-7/8" tall x 1-1/4" deep

In regards to a sealed transmission, that can make aftermarket coolers a bit more difficult to manage. Really the best option is going to be to have a local certified Ford dealer/mechanic install the cooler kit and change the transmission fluid when needed due to how a sealed transmission makes it more difficult. This is the route we recommend when trying to add a cooler to a sealed transmission.
