Was on my maiden voyage 2018 RT LTD , cruising along in 6th gear then all of a sudden sounds like the transmission exploded. Banging and clanking, marbles in a blender, burnt clutch smell. Pulled over immediately. Let it cool, won’t go into reverse, goes into first after a few tries, but bangs and clanks like the gears are butting heads. Only 40 miles on it. Taking it back to dealer but that’s another 3 1/2 hr drive one way. Anyone have any ideas what happened? Would like an idea of what may be going on when I talk to dealer on Tuesday. Oil level is fine, no fault codes.
