I believe it has a TH375 in it. Looks like the TH400 but has the TH350 output shaft.
If that's the case, you'll need a new yoke on the driveshaft to make the TH400 work.

You were right

I replaced the torque convertor. rear seal on the tail shaft, cooling lines there were a few dings on one, transmission pan gasket filter, and no more noise. pretty sure it was the torque convertor.
