If I try to rush it, it'd grind, no doubt, but so far, has never grinded. At least in my case, I don't care because never drag race anyway. A fraction of a second slower 1-2 shift is absolutely no problem for me. But yes, wish it was smoother. Changing to Royal Purple Synchromax oil definitely helped, to the point my tranny is almost perfect now. I also have a very slight notchiness on the 4-5 shift. But again, 6-5 is perfect. Issue is the gates are very narrow, so if you hit them just right, gear change goes in perfectly. Otherwise, you feel the notchiness. I just learned to live with it in all my manual cars. Don't let it get to you, unless you have a real issue. Many times is wrong technique, like releasing clutch to soon before gear change is complete, and such. I'm still learning on my car at 8,000 miles, but those miles are mostly highway, plus I drive other manual cars, so remembering the quirks of each car is a lot harder . Good day.
Agreed i had a S2K with tranny problem that found out later that is not a problem anymore being notchy 1st and 2nd. when i got the ///M i assume it was suppose to be that way since it was new... but when i test drove some of the M3 friends and even the one at BMW lot it was smooth as butter 1st and 2nd even at cold start. I understand that fact that some of the cars are meant to be notchy but BMW shouldnt do that.

well i basically prove it that after they replace my tranny 1st the 6th shifts smooth as butter.BMW probably knows the issue with the 08 since no issues with 2009 6mt tranny. Also replacing the tranny oil does not completely fix the problem it will for couple weeks until the oil settles then notchy feeling comes back. usually when notchy tranny is a problem with the synchro usually fixes the problem but replacing the sychro sometimes does not fix the problem. when i had the synchros replace on my S2K they had to replace the gears as well after the fact the synchros were installed.
Yes, I agree to some extent that all MTs have this issue. However, when I compare 1 -> 2 in this car v. my E46 M3, I can feel much greater resistance while shifting. Based upon that, and what i've read on the forums, i feel i may have an issue. I would love it if someone else with a 6MT E92 M3 drove my car and reflected on any major differences between theirs and mine. Given Sean05's improvement in feel, I think there may have been some issues with 2008s. However, on the flip side, it is DRIVING just fine - so why mess with it? I am hesitant to take it in for this reason...

One of the reasons I asked (other than the obvious fact that I was concerned since I'm getting an '11 M3 with 6MT) was because if this issue potentially impacts ALL 6MT transmissions thru all the E92 M3 years then there is a chance that the replacement tranny that Sean got will potentially have this same issue repeat itself at some point, in which case the one solution to avoid this ever from happening again would be to do a tranny swap to DCT.

Last thing I ever want to do ever again is do another tranny swap ($$$)... my 323i came with the steptronic (auto) tranny and reverse gear eventually failed so I underwent tranny swap to 5MT. My 323i is perfect now with no mechanical or electrical issues from the swap (feels like the car came from the factory with a 5MT).
Tranny swap in the 323? Nice! I wouldn't worry about your 6MT E92. It should be fine on the newer ones. Even with mine, it's not enough for me to switch to DCT (yet). After 11 years with MTs though, it's becoming apparent that I will one day hang up the MT for good
