I don't think my trans got over 200. But I'm not rolling at 75, at most 65-70

But 25 degree change in 1 mile? And a 5.3l halfton could do it with out that jump? Not sure how it's supposed to do it on barely half the weight it's supposedly able to haul

In Missouri. This was on a 1hr trip. Had a halfton that pulled the same trailer never once saw that temp. This is engine coolant temp. Not transmission. It stays solid at 195

I do have tow haul on, I'm pulling a 32ft 5th wheel, 9500lbs

I called my local dealer who I trust alot, and the service manager seemed like this behavior is not normal and wants to see the truck. I will update when I know more. Again, only does this while towing. Not normal driving.

That's what my thoughts are, and why does it only climb when in 5th. Unless there is something wrong with the WP, or there's an air bubble in the loop somewhere. I know the WP is mechanical based off the front pulleys, and I don't think 600rpm would make that much of a difference in cooling power

I'm not talking about trans temp, my trans temp stays consistent at 190 when towing. This is engine coolant temp I'm worried about.

I will see what it does the next time I tow the camper, just seeing it rise that fast worries me is all. Unloaded mine does not go above the 210 middle mark, and in 4th it stays steady at the 210 middle mark while towing. It was almost to the 3/4 line mark which marks 235 degree mark within a mile of shifting to 5th

Yea, I tried to delete the 2 comments, wouldn't let me. It just worries me that the temperature climbs 20-25 degrees within 1 mile after shifting into 5th. Sitting in the upper half on a Guage on a truck that's supposed to be designed for much more weight concerns me after only 45minutes of driving. When a 5.3l never batted an eye at the same weight for hours on end in the same gear with a 3.42 rearend.. I moved to the 2500 just for the Payload assurance. Now I'm not so sure..

I'm new to the L8T 2500hd crew. We just took our first trip with our 10k 295RL. With my previous truck (halfton) I could pull the trailer in 5th (6spd trans) gear without engine coolant temps rising. Hauled this camper 9hours at a time with that halfton in 5th gear with no issues With the L8T it runs at 210 unloaded and loaded running in 4th. But when I let it shift into 5th also a (6spd trans) the temp immediately jumps up to about 230 or so after about 1-2 miles of shifting into 5th. If I manually shift it back to 4th it immediately drops back to the 210 mark. Is this normal? Or should I be having my dealership take a look at it. I am just stumped that being an HD truck does this, while the halfton I had didn't have any cooling issues.
