The original Ultramatic fluid was Type A which is NLA. Most folks today use Type F or Type FA which are thought to be most similar to Type A. Some folks use B&M TrickShift with good reports. Some of the Dexron/Mercon types have been thought to be responsible for problems, if it were me I'd avoid them and go with Type F.

If you're going to change the fluid, check the shop manual for instructions on how to also change the fluid which is retained in the torque converter, just dropping the pan drain will replace only a portion of the fluid. Fill from empty is 11-12 quarts.
