I have 200,000 miles on my 2005 Ram 4x4. I have had no problems with the tranny or much of anything else outside of routine maintenance. I also have a 1998 Ram 4x4 with 100,000 miles on it. No tranny issues with that one either.
I’m talking the newer ones and in northern Alberta oil field. I also can’t stand the lag from when you step on the throttle, until the time it actually goes.
Then of course there’s the difference in ride heh.
