My wife drives that car. I noticed yesterday that she automatically does 2nd and then 1st shift. So, she figured this is the best way to shift and she does it automatically. Well. I don't really like that. Transmission feels "notchy". I drive 540i/6 and it's not like that at all.

Will see what happens at dealership, will replace oil when it's out of warranty. I use Neo oil in 540 and it helped a lot with 2nd gear synchros.

Folks, what about shifting from 5th to neutral? Does it go into center automatically? Or you have to move it there?
