Maybe the flexplate bolts broke.

 

When you were turning the flexplate was the torque converter turning with it? If not then something broke, maybe the bolts.

 

Saw this on a Chevy some years ago.The flex plate broke around where it bolts to the crank . The bolts were intact along with a section of the flex plate.
However in his case he could still drive the truck somewhat and it made a loud rattling noise.

 

Just the flywheel turns, sounds like the bolts or plate broke
Thanks for the info
Randy
