Normal transmission temperatures with Trailer Tow Group IV cooling package
I have a brand new 2019 Dodge Durango SXT which I purchased for towing a 17 foot Casita trailer. I haven't towed yet because I don't yet have 1000 miles on it. I just got back from a 150 mile freeway trip, 95 degree weather, and the whole time the transmission temperature was between 195 up to 200 a couples of times. I was driving in the normal Eco mode. Changing out of it didn't seem to change anything.
Is this normal? It seems very high as I read things on the internet. I've sent an email to my Dodge owner/general manager contact. This is making me so nervous. I'm a recent widow, and scared of getting ripped off.
Thanks for any input. I'm curious if there are Dodge specs for what the temps should be, both towing and not towing, with their factory cooling package.
You'll notice that, along with the numeric temp, there's a semicircular gauge. The transmittion in my '19 GT Plus sometimes hits as high as 220, but if you look at the gauge, it's barely above the center point. I would assume that any temp toward the middle is normal.
I did see that, but I also see all these charts that say transmissions don't last if temps get too high.
I've got my sales guy talking to the transmission specialist mechanics shortly to see what they say. If they say it's OK, I'm going to ask for a reference to the documentation. And this is all via email, so in writing, for my files. If I get all that then I will feel better.
"The bypass valve directs fluid back to the transmission lubrication circuit until the fluid temperature reaches 194 degrees F.* When the fluid temperature reaches this threshold, the bypass valve opens and allows fluid to flow through the cooler, then return to the transmission.* "
pg 95 references high temperature strategy at 248 degrees
So the forums show some guys experiencing the same thing, which is neither here nor there, but the FCA document makes it sound as though 194 degrees is fine, and that 248 degrees is the "red line".
Could you please share this with Jacob the service writer, and ask him to please ask the transmission tech guys to find me a spec sheet or something similar to the FCA document above that says these temps are within spec?* I'm inferring it from what I read, but if I could just see it in print, then I could put this to rest.
It may sound silly but remember that the internet is full of these charts below that say 175 degrees is optimal, and it sounds like this transmission is never going to do this.

I double checked last evening. Air temp was 72 F, driving at 68 mph on a flat highway with cruise control on, a/c was off of course. My '14 V6 has the factory tow package and HD cooling. Trany fluid temp was at 190 F.
