No issues with mine.... OD shifts are taking some time to get used to...
7 to 6 sometimes miss and goes to 4 but rev match revs up and gear indicator on the HUD shows 4, so i correct before letting the clutch out.
noticed a slight possible gear oil leak when parked on an incline, will get it checked at the 500 KM oil change...

We have all seen numerous posts regarding issues with the A8. I am curious to know if anyone has had any issues with their M7s. I have an M7 with less than 2k miles and it has been good so far, other than cold shifting from 1-2. All of my manuals have been this way though. I have had several M6s and they have all been bullet proof. I am not trying to start an M7 vs A8 thread, just curious.

Best standard that I've ever owned... tight shifting, smooth clutch, and hill assist makes it feel like it's cheating.

No problems at all. 2015 with about 3500 miles (z51)

Easiest way to avoid any 7 to 6 shift issue is to trust the reverse lock-out (and you should trust it, it is basically impossible to go there mechanically), and as you're pulling the shifter back toward 6th, keep a rightward pressure on the shifter handle. It'll go right to 6th every time.

There is more to performance than 0-60 times. The A8 can't be reliably tracked with a fast driver without heat issues. Even though my M7 will top 300 degrees, it's still working while lapping a track. The A8's heat issues are well documented.

No problems here. The shift from 6 to 7 still doesn't seem natural, though. It seems like the highest gear should be down not up, I guess.

I'm not saying our manual is bad but
1-2 shifting is not smooth
2nd can pop out if your not careful
7th gear can be hard to find and is really not even needed

I've owned quite a few, and would say the C7 is 2nd only to the 2002 Honda S2000 I had a while back.

except for when it locked in park twice and I had to play with the clutch and gas to force it into neutral. Both episodes were a long time ago and I'm pushing 39K on my 14 vert. 
Is there a bulletin on this?

Don't get me wrong, they were great cars, but yes, my description of the M7 was accurate.
