I can offer this: Owned a 2021 (just traded) 3500 SRW HO/Aisin. It will sometimes hit a false neutral while slowing to a stop...If you accelerate, the engine will rev until it violently slams into gear. Being the Azzhole I am, I shove the pedal to the floor, redline it, and see if I can break something...Tried it many times, no breaky.
Ran 35's on it it's entire life. Pulled loads that the DOT scaled me on and threatened to tell my mommy about...No breaky. Loved to drag race it, putting it in tow/haul mode, shift into 4wd, winding up the turbo/rpms, releasing the brakes and let her eat...No breaky. I'm pretty sure, given the mileage your prospect has, if it hasn't broken yet it's not going to.
