727 not pumping fluid

Wondering if there is a way to re engage the tc without removing the transmission. Lugs on inner gear gone? Not sure about those. If it must go back to the trans shop as result of my own hand so be it. Real bummer.
Any chance of there not being any damage? Motor has break in time and about a total of 1 hour of run time.

If you have an hour run time without atf in the pump, a seized front bushing is very likely.
