I have seen posted more that a couple of times that the transmission changed for the 2015 year. This was to apparently stop the ghost shifting that some complained about. I have searched and can not find anything official that this is true other than just someone saying so on a forum. If true they were not totally successful with the new design as my 15 has ghost shifted a couple of times. I have not compared a parts list between years but I guess that would confirm if true of not. If someone has more info on this I would love to know for sure if true or just rumor.
