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.

Started shifting hard between 40-50 mph. (3rd to 4th gear. Problem got worse and eventually would not shift out of first gear-no warning light came on until this occurred and now it sounds like I may need a new tranny. If you have this problem it won't hurt to have the throttle position sensor tested. This may have caused the start of the problem. Should not happen!

Put in in gear, a big thunk until about 2 miles, then it works good all day. Just happens in the mourning after car sits all night.

I purchased a 2008 mercury milan with just over 93, xxx miles and about a month later (also about 1000 miles later) the transmission failed, I had to replace it, (a $3500 parts & labor job). itt was working fine for a couple weeks but failed again, I took it back had to pay to replace the mounts and it was doing well again for a couple days until now. it started to have problems again and now they said the solinods are bad and have to be replaced. I have to pay more money for a problem that ford already knows about but don't wanna do a recall. it's bs.

if I'm going 50 to 60mph and slow down to 30mph or so for a red light or curve and then push the throttle to accelerate it will down shift violently. I think it's down shifting into 2nd gear. it's done it since I bought the car at 90000 miles.
My Mercury Milan transmission started to fail at 54,000 miles and my transmission finally blew at 75,000 miles. We were told that we needed to get our transmission Flashed (whatever that means) so we did that, and it failed to fix our problem. Our transmission had a Harsh and delayed shifting.

Shifting rough. Especially when accelerating at around 35 to 40 mph. Even slips out if drive occasionally .

I have to take my foot off of the gas when the engine gear doesn't change. It's like having to drive a stick shift with out having to shift, it's a complete both and worry. I barely let others drive my car because of it. I'm affraid the engine will explode if I have to wait for the gear to change.

Corroded transmission pan let the fluid leak out. Lack of fluid cause permanent transmission damage. No problems before this incident. Too bad because now it's junk.

Wrench light came on and began to have trouble shifting into 2 nd gear while driving, noticed a burning smell and car was having to work harder than usual to run. Took it to Robs Transmission on Greenwich and Harry in Wichita KS to have transmission looked at and the transmission fluid was burnt and filter was gritty. So I agreed to have the transmission rebuilt for 2600.00 with a two year warranty. This was in early fall of 2014 and in the spring of 2015 the same smell of burning fluid and trouble shifting began. Took it back to a Robs Teansmission in April where it has been siting for a month with no solution. Unable to determine a correct diagnosis and I was told to pick up car and drive it until it is broken and bring it back! So now I have just finished paying off the car and have a clean title except I have a car that doesn't work with a warranty from Carmax that expired after 90,000. I went to Carmax and they said sorry that there was nothing they could do. I did report the problem to Ford.com and that was it. Now I have a mechanic that is not sure how to fix the problem under their warranty. What do I do? I was planning on not having a car payment for the next few years by taking care of my vehicle with the normal maintenance routine. After reading the same complaints I see that nobody has a real solution and there is no recall!
