Determining whether my torch converter is any good?

I bought the truck with transmission having been overheated to the point that when put int gear there was no movement at all forward or backward. Pulling it showed wires melted to casing. There was very little oil on the transmission and the torch converter was bone dry. There didn’t appear to be any composites or debris in the fluid. I have a different transmission but need to know if the torch converter can be still good and put in? Blowing all the transmission fluid out like that, does that mean it’s ruined, or did it just shut down? Can putting fluid in it then draining it show the damage in the fluid, say by seeing nothing in it can it still be good.
