Good luck! Seems to be an inherent problem in the '09 and '10 transmission. I have had the transmission reflash done and posted multiple times in this and another forum and have yet to find anyone say that they have had this problem fixed. I now have 7,000 miles on mine and it still does it. The transmission is supposed to be "adaptive". So far that hasn't happened with mine, however, I have become more "adaptive" in learning how to drive to prevent it from doing it as often.
Had it, so you can check it off someone has had it fixed, oh my dad as well. IF the dealer performs the TSB to perfection it WILL work. However its a pretty involved reflash not a simple hook it up walk away. If you get your truck back from the dealer and you dont have 20+ miles more on the OD then they did it wrong find a new dealer. My truck had 100 miles put on it during the reflash. To say no one has had it fixed is ridiculus cause if you DID a simple search on THIS FORUM many people have had it done and it worked. The 5k thing is BS it should shift fine from the get go, had mine done at 4k I was experiencing intermittant harsh shifting. Had it done, from that moment on it was like NIGHT AND DAY.
To everyone else there is a TSB out there here are the links to all the TSB ford has produced for the F150. I suggest you read all of them and 90% of the issues people come on here and complain about are known and have a FIX. Time to do some research on your own and quit jumping the gun on issues without first inquiring about the issue. Here are the links EDUCATE yourself. I know I cant spell, dont care.

I have a 2010 F150 Platinum that has been doing the same thing since I bought it in March of this year. I have had it back to the dealer 3 times re the problem. And each time they "flash" the transmission and reset the adaptive learning process. I now have 14,700 miles on the truck and it sounds like the rear-end/tranny is going to fall out when it downshifts from 2nd to 1st.
The dealer can't duplicate the problem when I'm there of course and is telling me that Ford says a "bump" when downshifting is normal.
I say, NO, a $51,000 truck doesn't come with a harsh downshift.
I'm beginning to think the 6 speed tranny is problematic, Ford knows it, and is trying to down play it until they can figure it out. Meanwhile, I'm being told my driving style may be causing the problem.
Huh?
Anyone else dealing with this stuff?

According to the Ford posted info, the TCM adapts in two ways, first is to adapt to driving style and second is to wear in the mechanicals. It has a "learning and predictive algorithm that tracts how the operator drives and then selects shift points based on comparison of data tables and the measured "style" of the operator. Generally there are limits on how much the TCM can adapt during each " session". A session is a key start. When the key is turned to " on" the inboard systems boot up and check or modify parameters based on the previous session which ended when the power was removed and the computers shut down. If the style adaptive code has not reached the set point selected, it will incrementally change it's set points the allowable limit for that session. This continues until the adaptive settings match the driving style demanded.
So, a consistent driving style should cause the TCM to adapt within a reasonable number of key cycles. If you drive consistently. If you drive hard one day or week, then sedately for a week, the TCM has to integrate a lot more data to map the diverse driving styles and Figure out how to accommodate them.
If you drive very differently on different days, you may get some strange results from the TCM.
also, the Ford write up says the TCM will modify it's behavior on the fly, as in hard cornering it will inhibit shifting to maintain traction. So it may be that some seemingly anomalous behavior is a result of road conditions.
The wear adaptive feature attempts to measure wear on clutch faces and modify variable parameters to reduce or eliminate degraded performance due to wear. It works to maintain shift quality even as the tranny wears. This adaptive feature comes into play as miles and wear is accumulated.
In the Cadillac CTS transmission, hard down shifts are a result of bad data compare between the engine control module and the TCM. This can be addressed by diagnosing thecsource of the mismatch, generally a problem in engine hardware, like a dirty MAF or worse case a cam position servo sticking.
If I had hard shifts I would do a hard reboot by pulling the power, and see if the reset system no longer has the hard shift. If it still shifted hard, I would go looking for a dirty MAF or bad connection.

for those who are interested, here is the article I found
Adaptive Transmission Control (ATC)
What it is: The Adaptive Transmission Control system recognizes individual styles of driving (e.g., aggressive vs. Relaxed) and adapts transmission shift parameters accordingly. Two types of ATC are adaptive shift-scheduling and adaptive shift-quality control. Adaptive shift scheduling uses information to assess driving style and decides when to upshift or downshift. It also can identify uphill or downhill gradients and recognize hard cornering. This helps inhibit shifts that might be annoying to the driver or affect vehicle stability. Adaptive shift-quality control uses information about the vehicle or environment, such as changes in the transmission due to wear, to improve the quality of shifts. This system can also adjust shift smoothness to suit driving style (e.g., crisper shifts for aggressive driving or smoother shifts for normal driving). How it works: Adaptive Shift Scheduling uses a microprocessor to read signals from various sensors. It uses a complex algorithm and ongoing memory to decide when to shift. For example, high lateral acceleration during cornering may prevent shifting even if the accelerator is suddenly depressed or released. This helps avoid potential loss of tire grip due to load reversal. Shift points can be based on calibration curves in memory. Adaptive shift-quality control adjusts parameters that affect the speed and smoothness of the shift by interpreting data, including driveline feedback from various sensors, as well as post shift parameters. Customer benefit: Improves shift consistency and transmission durability and allows for shifting that is better suited to specific driver styles or operating conditions. Ford status: Available on many North American vehicles.

What really amazes me about all of this is how Ford can just dismiss this issue as so many have stated.
Obviously, not everyone's transmissions are having these symptoms! I've also spoken to many 2009 and 2010 F150 owners who feel their tranny shifts as smooth as silk. So, there has to be some other underlying issue with the people who are having these shifting issues with their trucks. Maybe during assembly some technician wasn't paying attention or some defective parts were used. It just doesn't make sense!
There, now I'll get off my soapbox and hope this issue will be dealt with to everyone's satisfaction.

mine does it every so often.... if you believe you tranny can "adapt" to your driving I LOL at you... Ford can't keep a 3rd brake light form leaking wtf makes you think they can make a tranny "adapt" LMFAO....

My 2010 has some shifting problems only when I am going slow through town and through lots of lights. Not really problems but really just a little harder shift. I find the problem only in city driving.

My truck just went over 16k miles and was perfect until that point. As soon as the weather got a little cooler the transmission started acting weird. Just as a sidenote, I do have an sct tune. Not sure if it makes a difference.
I pulled off of the highway and into a parking lot the other day and as I was stopping to let someone pass then moving into a space the transmission shifted down into first gear and lunged the truck forward. Id thought I had the driveshaft bump problem but now im thinking it was a hard downshift this entire time. Is it really true that theres no software upgrade for the 2010s?
