2017 Ram 3500 Aisin Trans shifting weird question

[RDuncan]

I was pulling my 28ft toy hauler through Montana recently. The truck was operating flawlessly except for one day we had driven about 400 miles and stopped to eat. We then continued on our way but when the truck reached 40-50 mph it would buck and jerk trying to go into upper gears. I pulled the truck over and shut it down for a minute. I then restarted it and it operated fine after that with no check engine light or codes. I just assumed a computer glitch but still has me wondering? Anyone experience anything like that or have an idea? thanks

How many miles are on the truck? Have you serviced the transmission? That's really odd, I've never experienced anything like that with mine.

Its got about 15k on it right now.... have not serviced transmission yet. The only thing I can think of that I did different was I pushed on the tow/haul button while underway. Normally I hit it before moving. I have put about 2000k miles on it since and without a problem. Thanks

TH is to switch on the run, no problem.

TH can be disengaged or engaged on the go, without issue.

I also haven't ever had that issue.
