While I’ve never had an actual mechanical issue with the engine, it is on transmission#3.
The first two lasted to nearly 500k each, one secret to my tranny longevity has been that I bypassed the thermal valve with a revmax bypass kit and regular fluid changes.
I also pull trailers frequently, so it’s not like I used it as a grocery-getter.
Last year, I pulled the cab on post at Fort Campbell auto skills shop myself and completely tore down the engine to the short block ONLY because it had several oil leaks, the front main cover, oil filter cooler, valve cover cracked, etc.
I put everything back original, with no headwork, block work, just all new gaskets.
I deleted it in 2020 at the beginning of Covid with a RaceME Ultra tuner and Sinister diesel delete kit, and I installed a 60-gallon Titan tank and an Airdog system.
That is the extent of the mods to the truck; everything else is original.
