hahaha.. good one... you got nothing to worry about..,, there are a few here that had to deal with with winter temps you probably will never see. at that point the main thinking is to keep it in the positive numbers in the cab.
check how to's in the garage.. i am sure there is whole thread about this in there.
hmm don't see it.. i am sure there are at least a couple on this.. there used to be one about easy changing your own ATF.. hmm.. bump them up if you come across either..
bad design.. the baffles are too tight.. the other thing that happens is that nissan recommends 30k ATF change interval (i think) and who really does that.. most never change it until it blows up about 100k... that's what i did..
so once the cooler gets plugged then all your issues quickly shift to the trans itself.. i saw the atf looking crappy in the morning.. the truck didn't make 100 mi.. maybe 60 or so.. i tended to check the oils on that truck pretty often.. at least a couple times a week, i'd say...
