Will the Derale Series 8000 Plate-Fin Transmission Cooler Kit # D13504 Fit a 2007 Nissan Pathfinder

Question:

I have a 2007 Pathfinder and wanted to protect my transmission now that I am towing a camper trailer. I am interested in buying the cooler part: D13504 from etrailer. I have 2 questions: 1. Will this cooler fit my vehicle? I do believe so but want to make sure. 2. If so, after installation will I have to add more transmission fluid to fill its capacity? You have a great video on line for a 2005 Pathfinder installation but it did specify the need to add fluid. Thanks very much for your support and look forward to your reply so soon I can purchase and install.

When it comes to transmission coolers and whether or not they fit a vehicle you simply need to make sure that you have enough room for the cooler. We only have certain transmission coolers listed as a "fit" if we have actually installed it ourselves or have heard from a customer that they got it to fit.

Since the Derale Series 8000 Plate-Fin Transmission Cooler Kit # D13504 fit a 2005 Nissan Pathfinder (as you can see in the installation video that you referenced), then it should fit your 2007 Pathfinder just fine. Just make sure that you have enough room in your engine compartment. The cooler dimensions are 11" wide x 12" tall x 7/8" deep (see attached photo).

I have attached some helpful articles on installing a transmission cooler for you to check out as well.

You will need to add more transmission fluid since you are essentially enlarging the tank for your transmission fluid but there isn't really a specific number that I can give you for what will need to be added because it all depends on how much escapes during the installation and how full it is now. Simply check the transmission fluid dipstick to know when you have added enough.
