Harsh or Delayed Shifting of Automatic Transmission on Lincoln MKZ

The automatic transmission may develop shifting concerns. On lower mileage vehicles, upgrading the software in the powertrain control module (PCM) and the transmission control module (TCM) may correct the problem. As the mileage increases, internal transmission damage can occur. Repairs could involve replacement of the valve body or a complete transmission rebuild. Whenever major transmission repairs are made, it is important to be sure the PCM and the TCM have the latest software updates to help prevent these issues from reoccurring.

This is a random intermittent problem that cannot be purposefully duplicated. Occasionally, the transmission will shift so harshly that it feels like I've been rear ended. It will continue to do this for a few minutes and then the problem goes away for weeks. Still under the drive train warranty for another month and half, so taking it to a dealership.

Downshifting very hard! Valve body was replaced under extended warranty. Shifting normal now. At the same time my air conditioner started blowing one side hot one side cold.

Problems shifting, especially when going up hill. Although my car has 160,000 miles on it, it's been doing it for probably 30,000 miles.
after a "shift control fault" chimed and cleared and the dealer reset ALL the codes have an intermittent loss of power and hard shift into gear while accelerating. Happened as frequently as 2 times in 1 day. 4 times in 400 miles in 2 weeks time. At the dealer for 7 days already with no calls of what the issue can be.

Hard shift into next gear when it hit around 30mph. Took it to dealership and they reprogrammed the transmission and still does it. Will be taking it back.

The car has trouble shifting into gear - worse when going uphill
2013 Lincoln MKZ- AWD29,000
Very hesitant shifting between 1-2 and 2-3 coming off full stops. Happens at low or high speed acceleration. Had the software update by dealer....this led to a somewhat better gear transition....but not really smooth....the way you would expect!
I had 2 sensors (I guess in the transmission) that needed replacing and now it seems to be working fine (I just picked it up today).

i will be driving and all of a sudden the mph will drop down to 0 and the car jerks really hard; like its going to cut off/ missfire.

dwlay shift of gear
I have noticed an increasing issue with the timing on the transmission shift. The car jerks into the next gear around 30mph when slowing down. I think it also has the same issue occasionally when increasing speed, again around 30mph. Car is not under warranty anymore. Any suggestions on whether the dealership is the best place to start. They tend to be more expensive than other shops.
