I've had a knocking from my transmission for at least a year and a half now which I'm pretty sure is the DM flywheel. The dealership thinks it is as well. I've also got the 1-2 clunk.

So is there any danger in driving on the bad DM flywheel for a while? The clutch seems mostly fine and I'd rather wait till it's about to go to replace the flywheel. I'm not risking my transmission or anything, right?

If it were to jerk and make the clutch itself explode I would think something would/could possibly go terribly wrong.

Don't worry about it, your clutch should go before the DM will and when it does grab a nice new Viva SM.

My car has the same clunk as yours at various speeds...which I also think is the flywheel. I compensate by revving a little more in 1st (3-3.5K) before shifting which seems to be a bit smoother...also the smaller of the two trans mount bushings used gets busted which makes shifting a little less crisp (sad face).

An out of balance DM flywheel will be very hard on the synchros, so you could be looking at a full transmission replacement if you leave it too long.

Don't worry about it? Anything out of balance in a drive train not an ok thing.

Videos of the tapping DM flywheel. Don't have any videos of the 1-2 clunking yet.

my last car with a DM flywheel made that sound and it was just throw out bearing chatter. It would go away when you depressed the clutch.
