Thank you for the feedback, Jess. I am also hoping that this is normal. Since in "D" mode shift from 2nd to 3rd gear is as smooth as from any to any gear. I also found information that ratio difference is the most between 2nd and 3rd gears on those BMW ZIF 6-speed transmissions. Maybe that's the main reason then switched to 8-speed in F models, to resolve this issue of rough switching between 2nd and 3rd gears.
