hard shifting 833

I have had more than just my Dart with an auto trans. My 73 Road Runner clone had an A 833 OD trans that I overhauled and put in it. I had problems with it not shifting very smoothly also because I ran 80-90 (back then I thought thats what ALL manual transmissions used. I was discussing those problems with my buudy (as I stated) just a few days back and he told me about the fluid and what I should have been using. Grow up. You have no clue.
