Take it back to the dealer.
Never mind the posting, your truck is out of that date range. But take it to the dealer

When was your production date? TBH, my trucks falls out of that range but something ain't right with mine ether.

Edit: to clarify, Occassionly, I feel like coming in and out of 3rd there is a kick back kind of, but I can never replicate it.

There is a lag between those gears if you do not hit the Excelerator hard enough. It’s like the truck doesn’t like to be driven in eco-mode. Lol. Honestly though. I’ve noticed when I’m easy on the gas pedal it does it more. But if I give it a good amount of acceleration and the trans shifts fine

Yea that's it. So that's normal? Or just a "glitch" that no one really cares about.

I was hoping it would get better after the break in period. I have 1000 miles on mine. I bought the bank’s pedal monster to see if that helps.

The low speed behavior when empty is not great on the 7.3. Mine does perfect when it has a load on it so I assume that is where they spent most of their time testing and tweaking. Just donesnt feel like this truck wants to be empty tooling around town.

I haven't experienced this with the 6.7. I'd say this probably goes beyond a quirk, and should be looked at by a dealership. Do you happen to have any videos of the behavior? Hopefully it's something that can be reset/reprogrammed.

+2 on the truck driving better under load. Crawling through my neighborhood is always unsatisfying the way it shifts.

Same here and I think the diesels do better because they are heavier and the power comes on differently with the turbo, could even be the way the torque management is limiting power, dunno but there are definitely more complaints with the 7.3, its touchy off idle and messes with the trans programming.
