I am facing issue with my 2018 transmission
Its noticeable shifting when slowing down/accelerating. There is also a jerk in the 2th gear, when accelerating from 10 km/t there is a slight ' jump ' that can be annoying aswell.

The problem is the same regardless of drive mode ( sport - eco ) and is there on electrical mode and gas mode. auto H is off, i have reset adaptions and scanned for faults.

Next step is replacing oil.

Any recommendations here for further solutions?

You can reset the gearbox as detailed here: https://f30.bimmerpost.com/forums/sh....php?t=1182679

Reading around here, the oil / filter service for the ZF 8 speed is recommended at 100k km by the manufacturer (62k miles), although many do not get treated until later.

If those don't help, you could have a mechanic check for any fault codes, which would help identify a root cause.

@Sooke1945 did you find the issue ?

Only thing I can add, is that when I had a 335, same symptoms, BMW replaced my transmission. Hope he/she has a warranty or knows how to do this. FYI, it's not hard, as I did this on a 650..
