Knocking or torque converter noise

I did notice that their are 4 bolts that hold the bell housing the the motor. One of them was loose and I tightened it back up.

 

I've gone through 2 flexplates. They both sounded like that. 3.4 though

 

Gonna take it in cause I’m to busy with work

 

Been so busy working recently so I thought I would take it to my mechanic and see if he could diagnose. Should of known already basically did what I did and listened for it. Said sounds fine. It’s a shame mechanics really just want you out and Gone. I know there are a few who really care, but this is why I always try to do everything my own. Gonna end up doing it anyways so.
