Hey all. First off I have a 05 magnum sxt 3.5ho with 4spd auto 92k. Had been having prob with code 300&304 multi cyl misfire & misfire cyl4. While addressing this issue the trans takes a dump with no warning. Now this car driven dailey by my wife like an old lady(,I drive it once in awhile just to keep carbon out of it due to valves not turning under 3500 rpm) just backing in to parking spot hear big clunk no reverse or any gear but low. broken hard part for sure. Now has anyone else had this prob and is it any way tied to misfire codes? I would not think so but with the comp age who knows. Any input would be appriciated Thanks
