Bucking when going slow

Mine was built in April 2011 - trying to find Job Number - and does the same thing. When I took it in for the first oil change I didn't say anything about it, hoping maybe it would come out clear of this issue. No love. But my driver's door seatbelt rattle is gone!
Been planning on taking it back for this specific "bucking" issue. Seems to really only happen until engine is up to normal operating temperature and the colder it is the worse it is.

I have had it happen then. Also when I go to local store, close and slow drive. Even after I come out of store on the way home. Guess common point is not warmed up. Also feels like engine, not transmission to me..........
It starts stuttering, I give it a little more pedal, nothing, back off and then go and it's ok.

Really, only Darren?
When this happens and you press the pedal it stutters. I am not sure it is a transmission issue or something else. When it comes out of it it drives fine. It's only on slow accelerations to a slow spped (like in a 30 mph zone)
Guess I should stay out of those.
I am tempted to ask the dealer to reset the adaptive learning thing. Will they do that by just me asking?

But I agree somewhat annoying. and was curious about resetting the adaptive tables as I kind of babied it the first 900 miles or so. @1600 now.

my build date is 6/2011. I only notice my truck "buck" when I press on the go pedal as if i'm about to accelerate somewhat aggressively but then immediately get off the pedal completely, and then press the pedal modestly. The truck still thinks in needs to downshift to accelerate, but seems to change its mind during the process and causing a hard shift 'buck'.

My truck does the same thing. Build date....9/11, 13,000 miles. Ford says all flashes are up to date.
It also "sits down" between 1-2 and 2-3 when shifting.
The only other thing I've noticed is once when in cruise mode at about 80kph, I started up a slight incline and the thing started bucking like it wanted to downshift. I pushed the throttle and it quit. I haven't noticed that problem again since.

By "sits down," do you mean it acts like you pulled your foot from the throttle then continued a second later?
Mine "cuts out" shifting into 3rd after a cold start but it's not the shifting issue I used to have.
This is an engine stumble. No bucking though.

Yes, that describes it. I have felt that engine stumble as well.
I knew every tick and tumble of my '01, 7.3. I drove it for eleven years from new. I hope I have much the same luck as that.
Of course I did have quite a few mods on it too.

unknown problems
That is what Ford says when they can't figure out what the problem is. Except for the time they couldn't fix my radio and after several visits and hours at the different dealerships, they responded with "We give up!" "We don't know what the problem is?"

Continuing this nonsense.........while attempting to pull onto a busy hwy (truck at operating temp), I mashed the throttle and pulled into traffic..........and there I sat. I know it was no more than a few seconds, however, when entering traffic, maintaining the flow is very important. It's a crappy feeling not knowing if others can avoid the idiot that pulled out and almost stopped in traffic.
Unlearning years of driving habits and old faithful vehicles will take some time. It's hard to believe that this is "business as usual" for these trucks.

It's scary if u happen to bump the brake pedal when u need to pull out and go quickly. Stupid safety thing where u can't go when the brake pedal has been touched. I really don't like the drive by wire system we have, but there's nothing we can do about it unless we get tuners.
