You can certainly use the Derale 24 Inch Frame Rail Fluid Cooler, # D13225, for your 1999 Ford F-250. You would also need Derale Radiator Adapter Fittings, # D13025, for the 7.3 liter Powerstroke. Any transmission cooler will could essentially be considered a remote mount application. I have included a link to the coolers recommended for your truck and engine. I have also included a link to our transmission cooler FAQ article and a video showing a typical installation.
For your truck and the mountainous terrain, I recommend the Derale Transmission Cooler, # D12904, with the D13025 fittings mentioned above. This is a class IV cooler rated for up to 12,000 pounds gross trailer weight.

Is the Derale Transmission Cooler D12904 still the best heavy duty option for the early 1999 ford 7.3 4r100 to date.is it made in USA? or are there better options today? The Mishimoto 7.3L Transmission Cooler is highly rated in aftermarket. Thanks
