Transmission lags shifting from 3k rpms to 4k rpms
My 1999 E55 with the 722.6 transmision seems to start shifting at 3k rpms but jerks as it in gauges at 4k. I believe its only 2nd gear going into 3rd. Anyway its seems to be that gear only. This only happens when I press the accelerator to 50% or more. if I ease into the throttle I can get to 0-60 quicker and the transmission shifts fine. Its only when I floor it that this happens. The best way to describe it is that it feels like a turbo spooling up from 3k rpms and at 4k rpms it throws you back in your seat. Any help will be useful. I dont want to start throwing money at it.

Make sure the "S/W" switch next to the gear selector lever is set to "W". "S" causes more aggressive shifts I find.
Maybe this is off-track, but it's cheap and easy to try.
Good luck.

What's weird is I've seen both answers. Some say it's about weather (winter v. summer). Others say it's "s"port.
All I know is mine is sure a lot more mellow shifting in W. When I Google around, I can find support for either.

You might try this too - not too sure if it'll help, but it's free and easy.
I also saw this comment further down in the comments FWIW -
I thought this was just the throttle response reset, TCM is reset via removing battery power for 10mins
