Lincoln MKZ Harsh or Delayed Shifting of Automatic Transmission

(23 reports)

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.

Harsh delayed shifting failure to shift into gear -
Slipping out of gear or not going into gear.. Transmission shop said 4000 to fix.. Nightmare.. -
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. -
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. -
Hard to shift from park to Drive at times. -
Rough shift into first sometimes. -
The car has trouble shifting into gear - worse when going uphill -
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. -
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. -
dwlay shift of 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. -
