It has been sitting for a little over 30 years. Any special considerations for the transmission? What kind of oil does it take? | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 |
Type A AT fluid was originally used.
People use Dexron Type II (or, Type III), not Type F.
Or, call Gene Berck at Restoration Hydramatics in Salinas, CA

The advice that I got was the same as Tim mentioned with Dextron.
I was told that type F would be too tough on the soft frictional surfaces of the clutches and bands. | | | | | Joined: Sep 2009 Posts: 433 'Bolter | | 'Bolter Joined: Sep 2009 Posts: 433 | I called Gene a few months ago an he said to use Dextron lll ... Vavoline Label
