Trans Temps While Towing with My 2019 3500

[OC455]

On my return trip from camping, I was curious to what trans temps were running on the 3500. On one of the long pulls on the way back that was steep and long, I had the cruise control set and was easily pulling the hill even though the truck kicked down into the lower gears and running the 3k RPM range. I toggled through the EVIC to the trans/oil/temp info screen and the hottest the trans got running up the hill was 170 degrees. Oil was 220 range and engine temp was 215 range so not running hot pulling the big hill on the way back.

I was running a little faster than I normally do but not excessive. I am impressed with the way the truck handled everything. I would really like to get a 5'ver and see how much better those tow than a bumper pull.

Good temps, my 8 speed has never gone above 170° pulling my 9000 pound camper

My 6 speed was running around 170 going up steep hills for tranny.

You're fine. My 2500 runs 172 to 175 towing a 10K+ load 500 miles each way recently in 90+ degree weather from Michigan to south central Kentucky through the hills of KY.

No issues with those temps. My 2018 3500 6.4L sits at 167/168 almost at all times, towing my camper or just cruising around. When going up mountains it get's up to 170 occasionally.

Yeah, the temps are good...wasn't worried about them at all, just posting the numbere.
