Harsh or Delayed Shifting of Automatic Transmission on Lincoln MKZ

Problem Description and Possible Solution

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.
Harsh delayed shifting failure to shift into gear
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.
Transmission shifts rough/jerts when cold, otherwise shifts perfect after warm up.
Harsh knock when shifting gears (P, D, or R). Now will only go in reverse.
Rough shift into first sometimes.
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.
Car has 20000 miles and am experiencing exaggerated shift into 3rd gear.
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.
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.
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.
Hard shift from 2nd to 3rd and occasional hard down shift. I owned a 2013 with 60,000 miles and dealer could not (would not) fix the problem so I got a refund. I now own another 2013 with 24,000 miles and it is doing the same thing. Time to talk to the dealer again. Too bad I love the car....
The shifting delays and I get a harsh jump going forwarf
Hard to shift from park to Drive at times.
Slipping out of gear or not going into gear.. Transmission shop said 4000 to fix.. Nightmare..
Shifting problem when going into overdrive. Typically moving at 40 mph and slight acceleration then bumping and shudder until the trany finally shifts. Can be stopped by accelerating or decelerating to help the trany slip into gear.
The car has trouble shifting into gear - worse when going uphill
Shifting from 1st to 2nd gear is very harsh.
shifting is jerky and worse when going uphill at about 40mph. I brought it in and was told it was my spark plugs misfiring so I had them replaced and it didn't solve the problem. Still jerks and have been reading about a lot of other with this same problem. Not okay ! Must go back to dealership
Warning light comes on and then vehicle will barely move, about 2 mph at the most. This happens while the vehicle is moving and very dangerous. Once you stop, turn the motor off, it has restarted and was movble but dangerous.
