RAM having adjustable spots is a waste of money as I set mine once to the furthest out position and never adjusted again.
My big concern for the FORD is the HOT transmission temps. I never see over about 172 pulling in near 100 degrees on long 6% grades. Most of the time I run 165-167.
Shows how dumb it is to do a leveling kit on a tow vehicle.
No denying it it has a ton of power!
I don't doubt the Aisin will do that if you say so ,the 68RFE will not running those long grades. I will see nearly 200 with my 68RFE , solo it runs a pretty consistent 172 , towing in hot weather it's a consistent 185-190 .
Idk how heavy you tow or your gearing or tire size, nor have I towed in over 100deg weather. (But you’re in the SW? so maybe pulling heavy in 110deg plus and maybe low speeds like switchbacks?).
180-190 won’t hurt anything imo. However are you familiar with Rams issue with the thermostat and bypass on the cooler lines?
I’ve never had an issue with it sticking at all but apparently some do. Some to the point of it totally sticking closed and frying the trans with cooking oil temperatures…
By comparison I’ve never seen more than 175ish. But that’s only towing an 11-12k toyhauler, 4-5% grade, ambient in the 90s. Although 3.42s and 37s are probably working it like a larger trailer.
I replaced the thermostat block on the last service here with the straight thru block that eliminates the t stat bypass. No chance of sticking and cooking the trans now ever. What I noticed is it still never gets over low 170s but runs much cooler under light or no loads. And it takes much longer to get up into the 150-170 range. Which I like. Although I could imagine it being cold blooded in extremely cold winter temps.
