My name is Mike and I purchased a 2015 EcoDiesel about a year ago. However, it has not been a smooth ownership thus far. After the Ecodiesel flash, my fuel economy went from 28-30 mpg hwy to only 25-26. About a month ago, my transmission crapped out on me (thankfully, it was still under warranty). I'm happy to report that my fuel economy is back to 28-30 hwy after the new transmission installation -- which makes me think the poor performance might have been because of the tranny problems. Anyone else experience similar tranny issues?
