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.

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.
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!

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.
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.
hard shifting at around 35-40mph
My Milan will drive for a little bit just fine but after about 15 to 20 minutes it will act up. It seems like the transmission will disengage and it will skyrocket the RPMs and almost red line my car. Then the RPM will go down and it will clunk.
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.
Shifting rough. Especially when accelerating at around 35 to 40 mph. Even slips out if drive occasionally .
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.
Harsh, shifting at low speed and delayed shifts at highway speed.
Shifts are consistently rough, and power is very uneven. Shifting into second is often a severe challenge.
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.
Hard shifting when the transmission gets hot
Really Really Hard shift at 65mph while going up a hill. Not the first time. Happens a lot at highway speeds.
I have the same problem. When driving the car shifts very harshly and sometimes does not accelerate, the RPMs will jump up and sounds like the car is high reving. When I let off of the gas and let the RPMs drop you feel another knock/jerk as if the gears were reengaging. I have yet to get the problem fix having Ford refresh my PCM didn't help and AAMCO doesn't know what to do but charge me to take the transmission apart to look at it.
Harsh up- and downshifts. The occasional "clunk" shift. AAMCO wants $900 to takes it apart and see what the problem is. I may just wait for the wheels to fall off....
Lug"s upon take off, as if it should be in a lower gear, yet won't downshift manually. When finally getting up to shifting speed (now aprox 50mph @ 1st shift) the transmission shifts hard. It also "Clunk's" into reverse, with a hard jolt.
Will not shift in highest gear p0257 code
harsh shift into reverse replaced trans and updated software and got a bad trans working on it now
hard shift, goes out of gear, they upgraded software pcm tcm nor sure what next
