Following this, I think I have the same issue. I have been very disappointed in shifting!

Same issue here. Was showing off my fairly new truck to coworker and he felt it shift hard. I was embarrassed.

Hey guys, so I picked it up from the dealer and although I'm still in the adaptive learning phase, everything was butter smooth. Even smoother than when I dropped it off and didn't have any problems with it.
Low speed shifts were good, and highway shifts seemed a little smoother. Will continue to update.

OK I will post an update on this for everyone's benefit.
The gent from Ford's official account asked me for my VIN which I sent to him via PM, then followed up with asking me for a bunch of personal information including address, local preferred dealer etc which I provided. Then a few days later, he responded with some meaningless bs such as "have you contacted your dealer about this issue and what did they say" This thread has the TSB, all I was expecting was whether my vehicle was covered and if they would proactively make a service appointment for me to get the TSB. But no.
Ford wants to look like a hero that is listening to its customers online and reaching out proactively. But it seems like just social media marketing bs with no authentic follow through. They did not help me and wasted my time thus far, have provided no meaningful information about this problem either other than what's already in this thread.

Its just the PCM (Powertrain control module). @dworley21 fixed this before this TSB came out by getting the dealer to apply a different TSB which had the same fix of updating the PCM.

Mine was good for the first few thousand miles but now that I'm at 12K it's getting to be dangerous. The weather is cold now so I'm sure that is part of the problem but even after it has been driven for a while it's clunks really hard at times. On top of that I have had it become unresponsive when pulling out into traffic. The other morning I pulled out of my driveway with the engine on and as I was accelerating all power cut off. The engine was on but no response from the pedal for 20 seconds or so. It was so bad I had to pull over and wait for the pedal to respond.
I love the truck but the bugs are starting to become a problem.

Hi there, Shawn. Will you send us a message with your VIN and dealership info? I can look into things on my end.

The TSB is good fyi. I had it done and just drove 300 miles over a mountain to get home.
I still may be in learning phase, but one thing that amazed me is the improvement shift quality when I'm manually downshifting as I'm going up an incline on the highway. They are mostly imperceptible now, where before the were very clunky.
Low speed 1 to 3 has been really smooth. Only way for me to make it not so is to stab the throttle mid shift, which is what should happen.
I also got 19 mpg going up 6k feet over that distance at ~73 mph 80% of the time, which is pretty dang good.

5 day update:
It's been really cold this last week (20's to 40s), and even when cold the truck shifts very well at low speeds. Also seems to hunt for gears less. I would highly recommend anyone with a pre 4/23 build get this done.

thanks for the info. I plan on having my truck flashed next time I’m in (near February). I am a March build date, and it’s running okay for me but I have noticed some harshness in lower gear shifts. Might as well get it taken care of!

My truck was dealer ordered and was in transit when I first started tracking it.
How can I retrospectively determine the Build date?
Thanks!

You can get an approximate date within a week or so from the blend date. The blend date is at the top of your window sticker just left of center.

Just got this done as well. I wouldn't say my 1-3 upshift was awful before but after the update it's night and day better. I'd highly recommend it.

I had this service done today. It seems better but I haven't done a lot of driving.
Take it in if your truck meets the criteria.

Driving in slippery mode today - truck started to slip in the snow, and revs went to 3200 in first gear under light throttle.
So I braced for the dreaded BANG into 3rd gear...
But low and behold, the revs came down, the 10r80 smoothly shifted into 3rd gear & off I went with my day!

I called 3-4 dealers in the DFW area and most of them were non-committal on even performing the TSB saying they have to "diagnose" my transmission issue first. Then they said to bring it in mid-February.
Still calling....

I had a CEL come on and they performed TSB 21-2131. I had mentioned the shifting issues and the TSB referenced here....got the usual well ford blah blah need to diagnose blah blah there's lots of TSBs it might not be related blah blah crap. Fortunately the 21-2131 is the same procedure as this TSB, the tech knew about this TSB and indicated it's the same fix and should make a difference. I can confirm the shifting is noticeably better on my drive home. I think it's starting the engine a little sooner/ensuring it's on in first gear, then moves to 3rd and stays there a little longer/higher RPM. Will report back after a few days.
