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.Google+

hard shifting from transmission. hard thump when car is put into reverse after that car has been running for 20 minutes
Shifts hard when I step on it, also sometimes at lower speeds decelerating.
Was told by a lincoln service shop the car needs a new Valve Body. They say the diagnostic report came back without any codes. Problem began with the LED panel on the instrument cluster working intermittently. Then I noticed it sometimes didn't shift smoothly. Finally, there are sometimes clunking noises, and sometimes a different noise when turning. Other times the car drives fine. The care went from having a clean bill of health at 84K to all these problems at 90K. All regular maintenance and oil changes have been done and the car is not driven hard. I understand this is a known problem with Ford/Lincoln transmissions.
I have problem with my transmission slipping and shifting hard. Now the problems has gotten worse...started experiencing slippage while driving and hesitation in acceleration.......

Car skips when driving up hill/or needing to increase speed intermittently. Dealer states no code upon diagnois referred to DTC update. Recommend 'value body' repair and reset codes. Still working to solve problem

The transmission is now linking fluid.
I noticed about a month ago slow going up hills and stalling when sitting at red light.

Car will not accelerate when merging into interstate traffic, it hesitates and slowly adjusts. I am afraid a semi will not see me. I am told to see a transmission person. Is there this not a know defect?? I just had to spend $2100.00 to fix this. Frustrating

Dealer also says it needs a new valve body. This will cost around $2200.00 to fix. I am seeing a lot of people are having the same issue. It has to be a manufacture defect.

Transmission shifts hard when it gets warm. It shifts so hard it feels like it is going to come apart.
