I would plan on a complete trans overhaul. Apparently the tans was having issues so they pulled the torque converter to check. Doesn't matter which component failed (main trans or converter), the complete trans -including the converter- needs to be overhauled.
When the converter fails- it sends metallic fragments into the trans. Same is true for a trans failure- it sends fragments into the converter.
