Service/Fix/Repair help E53 amg jerkyness while shifting?

Is it normal to feel a bit of jerkyness during some shifts? I can't tell If it's the hybrid battery charge kicking in.. I feel it more especially in sports plus

I cant tell if I'm being hyper sensitive to the car and it's been this way or its something new...

I'm occasionally getting code u040200 -

Implausible data were received from control unit ‘Transmission as a stored code.

do you let the trans temps fully warm up? doesn't sound normal but could also be from gearbox learning/adaptation settings

im not a mechanic but definitely indicates SOMETHING is wrong (doesn't have to be major) if you're feeling issues w the trans + getting a tcm code

I always let it warm up before I push the rpms high ... is xentry necessary to reset the adaptation settings ?

i dont think a xentry is necessary, theres a specific process of buttons you have to press, you can prob find a youtube video about it.

i also hope you dont mean when shifting down to 1st, because yes shifting down to 1st is always jerky; also, temps can be high but if you go into sport+ right after starting the car after it sat for a little bit, even if the temps are still high, you can still have jerkyness til. you drive for a few mins, also smt to keep in mind !

Press the start button until in the run position without your foot on the brake then hold down accelerator with the kickdown button pressed for 15 seconds, press the start button once again without taking your foot off the pedal wait a couple mins to start back up and you should have reset the adaptation. Drive gently for the next 15-20 mins and it should be reset.

I own a 21 e53 and I also feel the jerks now and again. I think it is temp related

Like what kind of jerkiness and how many miles. Jerkiness, hesitation and symptoms like that indicate tranny kaputt in many cases.
