Seems the MD AISIN does not need to be heated up and as mentioned they run cooler than any trans I have heard of.

This sort of issue is another reason I like my AISIN trans. It has a cooler and that's it, no heat exchanger.

My trans temp runs 165 towing or not and when climbing miles of 6% grades it may get as high as 172. OH and the trans is NOT tied to anything other than it's own cooler.

I just looked up your trucks cooling system on Rock Auto. You have two radiators. The secondary does not have a tranny cooler in it. The Primary or Main radiator DOES have a tranny cooler in it.
Look it up for yourself. They even have pictures.

Sorry my truck has ONE radiator. My truck is a 2015 and the 13 and 14 did have two radiators. I have no idea if the trans is tied to one of those radiators or not.

For fun post the pics.
