Stan,
I went over to my friends shop to tear apart a 4L80E trans I got off of craigslist for $80, he's been rebuilding transmissions for many years. He is also more current on todays converters for racing & street use.
I got the 4L80E trans mainly just for the case so I can mock it up on my Camaro to measure for a driveshaft & possibly make a cross member.
I asked him about the Yank converters & he says nobody uses those anymore.
He likes Circle D converters (warning, they are pricey
)

They are probably still good converters.
I have been out of the racing scene for a few years.
