The allison trans have issues too, my neighbor was stuck in texas with his for a week, dont put another dealer/factory trans back in the truck, spend the 8-10 g's and put an almost bullet proof one in from one of the aftermarket builders, i did the research a couple years back on these guys because i was going to put one in my 06 cummins but i ended up selling the truck and buying a 2020 ram laramie gas truck, just did not need a diesel anymore. i went back and re-read your psots and discovered its not a diesel, i still would recommend an aftermarket trans over the factory, good luck with the warranty from that dealer.
