It used to be that the six-speed Aisin HD transmission was an option, which wasn't a Stellantis product. Also, I'd immediately disable the AFM stuff, which has always been a threat to top-end lubrication.

My grandpa used to say that every American ought to purchase a Chrysler product once every ten years (if only to get the urge to do so out of their system) and sell it immediately afterwards. He was a Dodge fan in the same way that some people are Cubs fans; i.e. inured to disappointment.
