I'll bet your driver's door doesn't clunk like an old pickup truck when you close it, either... :-)

The M3 isn't perfect, it's okay to admit it....
blasphemy

(the trick for newbies to smg is to think of it like a manual, imagine what the computer is doing and why and then relate that to what a good driver would do, you'll see the logic and get used to it, after years i find no quirkiness in the smg (or maybe i have gotten so used to it that i adapted my driving style around it) anyway it's all worth it when you (really the computer) rock a flawless 2nd to 3rd money shift at 8000 rpms in S5 or S6 while some other guy is fumbling with a 3rd to 4th (or even 4th to 5th) shift and falling way behind in your rearview mirror.

i think it is the clutch disengaging, and it seems the only "fix" is to throw it in neutral....

unless someone else has any ideas....

go get the free SMG software upgrade. (did it when I was doing the recall in another thread).

I have an 05 with the clunking, and now it's almost completely gone.

Exactly. Happens to me too. I think this is what you're experiencing.

Since were sorta on noises, How much noice should a shift from like 1-2 or 2-3 make at full thottle in say S5 or S6. I know that the car is doing a lot, at it's not going to be quite. Mine just seems to THUD pretty loud sometimes. Just wondering.

I've only had it for about 2 months so far. Its a 03 Carbon Black SMG. AND I LOVE IT!!!!! haha. and no I don't beat on it constantly. Maybe one full thottle neck bender a week. haha.

Full throttle, pedal-to-the-metal, S6 shifts are LOUD.... as in SLAM.

It's the nature of the beast

Indeed. I’ve only had mine for a week and noticed this from the get-go. It worried me quite a bit so I did a lot of forum searching on the subject. Lots of threads out there about the SMG “thud”, “thunk”, “clunk” etc… Under most circumstances this is normal and to be expected.

Next time I drove my SMG after reading the OP, I saw exactly what he meant. Decelerating through 1900 rpm in 1st or 2nd, there is a clear lurch; almost as if the throttles open momentarily. 3rd doesn't do it. Interesting...

It's probably just the computer trying to compensate. I tried the popping into N technique and it solves my problems just fine. Thanks guys!
