I don't think they have built a new cast iron powerglide in 50 years.
Your only option would be a rebuild, if you want to keep it original and getting parts to rebuild them can also be a problem.
How original is your car? If it's not almost completely original, I would also consider a later model over drive transmission.
:laugh: Point well-taken. But I was meaning rebuild the original or drop a newer transmission in. The car is mostly original, but the interior has been partially restored. My mechanic gave me the name and number of a guy in Billings, MT who has rebuilt them forever. I'm leaning towards keeping it original.
