REALLY? BROKEN FLYWHEEL?

UPDATE: Okay, after telling me my truck broke the flywheel under normal wear and tear, when I called today after it being in there for 15 days the owner said they where waiting for another trans (3rd) to come in. I asked him what's my bill going to be?--$1104.
So he's still charging me for the flywheel and probably RnR.
Now if the flywheel breaking was normal wear and tear, why would he be replacing the trans under warranty again? Should I pay or should I feel lucky to be getting another trans?
