When towing my 5er over the Rockies in Wyoming when it was about 90F outside I never got over 185F, and that was downshifted into 2nd, at about 3200RPM I would like to see lower temps in tha Allison, but I know 220F is not dangerous, but 30 degrees hotter could be a real problem IMHO. Thanks for the heads up on the cooler!
Mine loaded heavy at 30k+ GCW through steep and winding hills runs 210-215 at 50f and the same yesterday at 97f. It's normal op temps, no worries.
