Transmission Cooler Recommendation for a 2007 Nissan Pathfinder to Prolong Transmission Life

Question:

Why does Nissan advise not to bypass the standard transmission cooler? What are the risks involved in using an aftermarket transmission cooler?

Typically the best setup is to use a supplemental transmission cooler along with the factory cooler instead of bypassing the factory cooler. What this means is that your transmission fluid will travel from the transmission to the factory cooler and then to the supplemental cooler like the part # D13504.

When picking out a transmission cooler the best way to do it is to measure the distance in front of the radiator and pick the largest cooler that will fit the area.

I attached an install video for the Derale Transmission cooler part # D13504 as well as an FAQ on transmission coolers for you to check out.
