How to love your Pathfinder
 Step 1 - Have your transmission cooling lines disconnected from the radiator! There is an external auxiliary transmission cooler that does the job already. The only problem you may encounter is hard shifting in extreme cold. You can, if you want put another auxiliary cooler on the truck, but unless you're maxing the towing capacity every day you will not need it. The stock cooler is very large.Step 2 - You've basically now cured the only problem you will ever encounter, except for some little maintenancy things. Enjoy!
