Unless over 100k miles transmission should be covered under drive train warranty. Exhaust (DPF) is too much grocery getting, and 13.5 to 14k# is nothing for the engine and transmission. Tires are a normal wear item.
Well, if his regular drive cycle is the cause (it was for me on my work truck as well), then that's all the more reason to switch over to a gasser. The transmission is probably related. I munched my Aisin because carbon buildup in the turbo would occasionally cause an over-boost condition. The Aisin is robust, but not very smart. It basically only monitors TPS and speed, rather than load, so it doesn't shorten the shift times during over-boost. When my did it, you could feel the 1-2 shift overlapping. Only took about a week before it was un-drivable.
