E92 335i - automatic transmission jerky?

i've noticed that when im shifting manually in my car and rev it up to like 6500rpm-7000rpm theres a little pause while i shift that is kinda jerky. i was thinking it would shift like it does when you rev it up to like 4000rpm-4500rpm, but instead its a jerk. is anyone else experiencing this or is my 335i just messed up? it usually happens 2nd-3rd and 3rd-4th...

heres the dixis 335i dyno vid for example.....look how fast the shifting is at redline...

how many miles do you have? mine got quicker and less jerky after about 3k miles... then i had to start over after the new fuel pump at 3800, since they reset everything including tranny adaptations

Shifting so close to red line you might be triggering the rev limiter (fuel cutoff)

I never revved to 7k since i dont really see a point. But when i shift at 6300-6500 in any gear, i know the jerkyness your talking about but i dont have the pause you described.
