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.

problem details
2008 Lincoln MKZ - AWD 36,000 mi,
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
2008 Lincoln MKZ - FWD 25,000 mi,
Transmission shifts rough/jerts when cold, otherwise shifts perfect after warm up.
2008 Lincoln MKZ - FWD 159,000 mi,
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.
2008 Lincoln MKZ - FWD 98,085 mi,
Harsh knock when shifting gears (P, D, or R). Now will only go in reverse.
2014 Lincoln MKZ - AWD 13,000 mi,
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.

Rough shift into first sometimes.
2007 Lincoln MKZ - FWD 75,000 mi,
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.
2013 Lincoln MKZ 24,000 mi,
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....
2010 Lincoln MKZ - AWD 55,000 mi,
Hard to shift from park to Drive at times.
2013 Lincoln MKZ - FWD 18,755 mi,
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.
Car has 20000 miles and am experiencing exaggerated shift into 3rd gear.

Slipping out of gear or not going into gear.. Transmission shop said 4000 to fix.. Nightmare..

The shifting delays and I get a harsh jump going forwarf
2007 Lincoln MKZ - AWD 71,076 mi,
The car has trouble shifting into gear - worse when going uphill
2007 Lincoln MKZ - FWD 156,000 mi,
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.
2013 Lincoln MKZ - AWD 37,000 mi,
Shifting from 1st to 2nd gear is very harsh.
2010 Lincoln MKZ - FWD 50,000 mi,
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
2013 Lincoln MKZ - AWD 50,850 mi,
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.
2008 Lincoln MKZ - AWD 36,000 mi,
Occasionally when the dark is shifting it suddenly feels like I've been rear ended as it slams into gear or locks up..it's done this 3 times since I had 36,000 miles..it now has 38,ooo and is a 2008 MKZ all wheel drive 6 speed trans. Is there a recall or a silent recall to fix this?
