Shifting Hasatation

Just a guess here, but it sounds like it isn't as efficient until it comes up to a certain temperature. I don't know if I'd consider that a problem or just a characteristic.
I have the 3.5EB and 10 speed. I haven't noticed this hesitation, but I pull out of my driveway and make an immediate turn, then another immediate turn as I go onto another street...it's probably doing that shift as I turn..so it's imperceptible to me.
If you get it checked out, let us know what they say. Or, someone more helpful on here might know what causes it.

I got my '17 Lariat in early January so I lived with this problem all winter. On a cold engine the normal mode shift from 1st to 3rd bogs a cold engine. Also, to a lesser extent the normal mode shift from 3rd to 5th.
Apparently this is just something you'll need to live with in the name of decreased fuel consumption.
You do have a couple of choices:
Let the engine warm up wasting time and fuel.
Be more aggressive with your right foot from dead stop. This makes it less noticeable.
Put it in Sport mode for the first couple of minutes until the engine warms up a little. This way the trans uses 2nd and 4th.
Just live with it. That's what I've come to do.
You would think that since everything from the engine to the interior lights are controlled by a computer that Ford could have programmed the transmission not to skip gears until the engine warmed up a bit but I'm willing to bet that this is the only way they can meet EPA emissions standards with a cold engine.

Mine lags going from reverse to drive, about a 2 sec. lag. Dealer says its normal. Same when I come to a stop sign and slowly turn without coming to a complete stop , it takes a moment for the trans to down shift. Go in for another oil change in a few weeks, will discuss again with dealer.

Or, do you just start it up, put the transmission in drive, and go.

Even the 6R80's do that when they're cold. Once they get up to temp, they straighten out.
And it doesn't have to be below freezing or anything like that. Just cold-cold. Around 45 degrees for an extended period.
OTOH, it might be something else. Can't tell from here.
Don't force it, let the computer do its job

What are all the advantages of the 10 speed transmission, that you mentioned? Thanks

Well, the 10 speed has the top three gears as overdrive whereas the 6 speed only has the top 2 gears as overdrive.
The 10 speed has a true direct (1:1) 7th gear, the 6 speed's top non-overdrive 4th gear is an under drive 1.14:1.
First gear in the 6 speed is 4.17 while in the 10 speed its 4.69. Not a tremendous deal but it might allow you to get away with a higher rear axle.
The 10 speed uses an ultra low viscosity fluid that is half the viscosity of the fluid used in the 6 speed. This reduces pumping and friction losses.
The more closely spaced ratios of the 10 speed do a better job of keeping the engine in its power band giving better performance.
None of these features are anything great when viewed alone but when taken together they do add up to reduced fuel consumption and less heat generated.
It seems that the automotive industry on the whole is going to 8, 9, and 10 speed transmissions behind smaller turbocharged and supercharged engines for performance and fuel economy reasons.
Ford may still have a few kinks to work out in the control software for their 10 speed but based solely on my experience over the last 6 months it seems to work fairly well.
