06 Ram (5.9) auto trans cooler and heat??
Just finished a 8500 K trip and noticed when ever we had little wind coming in the front end this tranny heats up. Highway speeds and warm weather no problem. Cold outside temps and slow lugging tyran...

I pulled the trailer up a steep incline perhaps an eight of a mile on packed snow and ice with chains on and tran in drive. But going very slow.
I did a few miles up some switchbacks in the late fall. It was in the 20's outside (not near as cold at you). My speed was around 20mph, and my trans hit 225 via OBD port. That slow of speed just doesn't get the airflow across the front cooler.
I haven't been concerned with the operation of the trans cooler, but there might be enough room for a slim electric fan to be mounted between the grille and cooler stack, but it is pretty tight up front. Another option would be to get a universal cooler with a cooling fan mounted to it (look at B&M). I wouldn't worry about it at all if this was a one time thing but if you frequent a steep climb at those speeds, a forced air cooler you might benefit from.
If the road is slick, drop it in 4-low, and then lock it in 2nd gear (or 3rd and T/H) and you can still get the TC to lock but at a much slower speed because of being in low range.
