If it is the flex plate, usually they just crack. Don't know if warming up would affect that or not.

the transmission was rebuilt a few months ago the mechanic said he flushed all lines and checked the converter he said was all good. the transmission shifts just fine but after warm up i get a grinding noise at idle.

If the trans was rebuilt, the torque converter should have been replaced with a new one.

If it wasn't replaced then that would be a real good place to start!

The only one that I've ever seen cracked had two cracks that connected three of the bolt holes where it bolted to the crank, all the torque convertor bolt holes were undamaged.
