I'm looking to purchase either the 18 with the 6 speed orthe 2019 with the 8 speed. I'm concerned about the 8 speed. I know that the 10 speed that Ford has been pushing for several years now is starting to have problems as they age. I'm concerned about the same thing for the new 8 speed. I actually took both of them for a test drive and honestly I thought the 18 drove better. There is less engine vibration and it seemed to shift smoother. I do like the extra miles per gallon I would get on Highway with the 8-speed though. Can anybody here give me some input or recommendation on which to get? Thx!
