Thats what I did with my old A8. I had the flush done twice and kept having issues. Found a deal on a M7 car, traded and haven't had a single issue since. Not to mention the manual is much more fun to drive.

I agree with your overall premise, that no car is perfect. Like several others here, however, I haven't heard about any pattern of M7 problems.

Based on the atchd, I doubt whatever "problems" exist are torque tube related. GM's bulletin indicates that issue is limited to "automatic transmission" C7...

As to M7 problems, I can only think of the occasional throw-out bearing failure, and a few issues with the reverse lockout.

An older lady owned the car and it must have went into v4 a lot. What I thought was transmission shudder, after the transmission fluid change turned out to be a bad torque tube. This was at 5400 miles. I think my best bet is to trade for a M7. The car only has 6k miles now. Thanks for the info.
I have a 2019 C7 with the a8 and a 2019 with the manual. The auto performs perfectly and is great to drive especially when I am in town or feeling a little lazy. As well it is faster and the remote start is nice to have. I am bringing it in tomorrow for the transmission flush just to be sure but there have been no issues yet. I did install a range device when I bought the car new.
