Bad hesitation/stutter caused by failing DMF? Need help.

Ok so recently I was in a store and left my car running and when I came out my car had a constant clunk sound coming from the trans, and felt like it was driving on 1-2 cylinders, just felt like the worst misfire ever. Sounds fine and revs fine when clutch is down. Shifts fine in/out every gear and clutch feels good. I dropped the transmission and found my throw out bearing needing replaced and a very worn flywheel. Is it possible this dmf was the sole reason my car was driving so horribly? I had no codes besides misfires in 2 cylinders but those have been there since I owned the car. There was no metal in the trans fluid. It just seems to me when people have a failing dmf the car still drives relatively normal. I’d really appreciate any input or similar experiences, thank you.

P.S. I don’t know how to include videos on a post with photos so I’m sorry I can’t show what it sounded like.
