Is There A Benefit To Running Two Aftermarket Transmission Coolers Compared To Just One?

Question

Question:

I am going to place the Derale D13503 into my 2001 Nissan Pathfinder and was wondering if there would be any benefit of putting two in or if one is good enough to help cool with towing around 3000-5000 lbs?

If you have the physical space you could install two of the Derale Series 8000 Plate-Fin Transmission Cooler # D13503 in your 2001 Nissan Pathfinder but that is unnecessary. This cooler measures 11" wide x 8-3/4" tall x 7/8" deep so it is unlikely two will fit.

Using just one of the coolers will do just fine at keeping your transmission cool when towing a 3000-5000lb trailer.
