727 not pumping fluid

And dont run it any more. With no fluid flow, its only a matter of a few revolutions and the bushings and washers inside will be toasted.

We are assuming that you had to pull the TC forward to contact the flex-plate to install the 4 bolts.If thats true, then I suppose its possible(but hardly likely) that the converter control valve is stuck.I say hardly likely, because you said no drive in any gear;which includes reverse. When in reverse, line pressure is unregulated and may rise to 250psi,more than enough to dislodge a TC control valve.
