Oh believe me dodge doesn't like most of the things we do to modify them or fix them. They want you to run the in tank fuel pump conversion for example but you can really only get a decent replacement from them for 400 bucks when you could get a decent frame mounted pump for the same price and you dont have to drop the tank when you need to replace it. The G56 in the 3rd/4th gens was built by Mercedes and Mercedes recommends there special oil (50w or something like that) and dodge says ATF+4. I would tend to believe the maker of the transmission personally... I could go on lol
