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+

Mercury Milan Harsh or Delayed Shifting of Automatic Transmission
Mercury Milan Problem
Drive Trains Affected: Automatic Transmission, Manual Transmission
Average Mileage: 78,394 mi (8,100 mi - 150,000 mi)

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.

hard shifting at around 35-40mph
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.

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.

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

Had to have the software updated due to the hard shifting. Car now has 99,500 miles on it and the hard shifting and slipping is occuring again. Was told by dealership that the Driveline was bad and needed to be repaired/replaced. Does this sound right???

I do not beat on any of my vehicles I Drive them extremely easy. I will be taking this car to the transmission shop this weekend hopefully the updating of the PCM and TCM will work.this car has delayed shifting and shifts hard occasionally between 2nd and 3rd and 4th.
