Did i damage my 727

So right now I have no cover on and new deep pan on with summit gasket and returned the 3ft cable to see if the 4ft will work if not I will just use the replacement one and go the passenger route. Also shifted it into park and it does hold. I'm just worried about the converter bolts somehow coming loose and hitting the block. I'll be able to inspect more this week. Has anyone encountered the bolts doing that and what about the debris in the tranny pan
