Type A automatic transmission fluid

[m7040]

I have an old Massey Ferguson tractor where the hydraulic system for the loader as well as the power steering calls for type A transmission fluid according to the original manuals. Can it be substituted with Dexdron III fluid?

you may actually luck up and find some type a from off brand bottelers.. but I see lots of recmendations for the dex III as a repalcementr for the b and older A

Yes, I believe so. From ftp://rohan.sdsu.edu/pub/mml/archive/Drivetrain/atf.txt

The A/AQ-ATF/Dexron fluids are BACKWARDS-COMPATIBLE. That means that all
transmissions that called for Type-A, AQ-ATF, Dexron, Dexron II, Dexron
II-d, Dexron II-e, or Dexron III should now be using Dexron III.

If it works in an automatic transmission that originally called for Type A, I have no reason to believe it won't work as a substitute for the Type A fluid your tractor originally called for.
