what fluid are you guys using in you 60's 727 transmission's these days?
Valvoline DEX/MERC. Name brand always tests. Better, you are paying for the additives.
Type F is a farce, the worst lubricating qualities of any ATF.
And why are the shifts former? Because it doesn’t lubricate well, it grabs because it’s not slippery. True story. I know many folks use type F with no problems, And that’s great. But I’m telling you the truth about what you are getting with the F.Type F if you want firmer shifts.
Drain the convertor and you'll have no more than a quart left in the trans... If you are still worried, change the fluid again next year. I would be far more worried about the color of what is coming out. If it's still mostly red you should be good to go.I'm assuming the fluid in it now is the original type A and there will be fluid left in the system. Wondering how compatible the newer fluid will be with the type A still in the trans.

thanks for the incite guys.
the car has 86K original miles when it was stored in 1974. Pan gasket is seeping fluid so I will drop the pan, replace the filter and install a new gasket.
