My wife's '13 Fusion Titanium - 2.0L ecoboost - has about 14,000 miles on it. Not sure when, but a while back I noticed that it was shifting hard between 2nd and 3rd gears. It would hold the RPM up for a bit too long and when it went into third you could really feel it. Well, last week we took it in for the fuel leak recall and told them to look at the hard shifting problem too. I really wasn't expecting much...I've seen some other people posting about the problem but no real resolutions. Well, they fixed it! The main culprit, evidently, was the main controller in the transmission. It's buttery smooth now.
Just posting this in case others come searching for the same problem. Looks like there may be a fix after all.
