David, I have seen this multiple times in the auto repair business, as far as a cause,  on cars that someone had removed trans & did not reinstall all the retaining bolts, improper alignment of trans/eng., guide pin missing, trans bolts loose, damaged when trans installed (pry bar nicks all over the flywheel caused cracks) found a rag installed between trans & eng., & also on NEW cars with low miles no previous repairs performed.         I also found three Mazda auto trans flywheels as Tracy did, with very fine cracks around the lightening holes ( not the bolt holes )  when we were looking for one to use on our RV6A rotary.  I even asked the salvage yard guy to check for me & he missed them & shipped me that junk flywheel.         David R.
