Original transmission is a Roto HydraMatic 10, sometimes called RHM 375. Also known as Slim Jim.

You can get a rebuild kit from Fatsco:

I unsuccessfully rebuilt the Slim Jim in my 64 98 years ago. It never shifted right before or after the rebuild.

I think I would rather tear apart a 6R140 in a new Ford Super Duty than another Slim Jim. I'm sure it would be an easier rebuild. LoL
