Hi. I was curious as to who has the most miles on the dart with the ddct transmission?? Have you had any problems with it? Original trans or been replaced? Does anyone know at what mileage to swap out tranny fluid with new?. My 2015 dart is the 1.4t with 91,000 miles. I just hope my ddct will last me. Mine was replaced new at 45,000 miles by the dealer from the previous owner. And the TCM was replaced along with that bushing recall. Should be drain and fill right?
