I have a 2010 MKX with 112k. The transmission was replaced early on under warranty according to the service records. but it is starting to shift hard mostly when slowing down and accelerating. I noticed it about a month ago when I hit the gas and it downshifted hard and slammed into another gear. Freaked me out. Sure enough, now it's starting to do that more regularly. For example, it is kind of sluggish, especially when going slightly uphill on the highway because needs a tune-up and so it downshifts to maintain speed and its not smooth like it used to be. I heard these trannts are not that great and '11-'12 models have a bulletin out. But how about the 2010? Any ideas? Thank you.
