Super tuning car runs good shooting for great

If it was mine
I would take the pump gear out of the pump house and slide it onto the TC. If it is in fact that loose, then I would want to know why, as that is not normal. I would also like to see how the TC engages the pump lugs.
I would also put the reaction support into the TC and the rear clutch as well, and make sure the guts are not clanging around, inside that TC.

I replaced the torque converter on Tuesday with a factory high stall. Noise didn't change.
Same clunk back and forth.
