After a hard pull on tow vehicle
After a hard pull do you do anything out of ordinary with your vehicle? I just wait for temps to get back down to normal before shutting off. Hard pull yesterday at over 90 degrees in higher elevat...

'01 6spd with Edge-EZ I cannot get the coolant out of the 'normal' range on the gauge. Maybe the hot trans temps helped push the engine temperature up?
As Old-Biscuit said, the 47/48RE transmissions do not circulate fluid in Park, so extended idle and cooldowns should be done with the transmission in Neutral.
If you frequent these speeds/pulls, install a lock-up switch so that you can manually lock the torque convertor to keep the transmission cooler.
I did a climb last summer with slow traffic and construction that had me running 20-30mph (my TC auto locks above 25mph when I manually select 2nd), and I was at 218* on the trans but the coolant temp stayed in check (maybe 210* at the most). When traffic stopped, I set my high idle at 1500rpm and in Neutral to get airflow across the exchanger for the trans.
