The transmission is your weak point when towing. Keeping it in the correct gear for as long as possible is what keeps temperatures down i.e. the torque converter locked on a gear consistently for as long as possible. I can say with 100% unwavering confidence that 37” tires on a 2015 Ram power Wagon, and towing is best done with 4.88 R&P front and rear along with the AEV procal adjusted correctly. Also you must mind your gear shifter, and stay on top of your transmission by purposely downshifting to lower gears. The above mentioned set-up allows you to climb most grades in 3rd gear with low temps, as long as you shift back down when ever the truck tries to go to fourth. On harder climbs you go to second gear with a load. This is mainly about discipline, and not letting your transmission sneak into higher gears and run up the temps.
My gearing was done by 4x4 Land in Topeka Kansas. They were excellent, and got everything perfect the first time. They know Rams, and install a lot of AEV parts. 4x4land.com
