The 727 and A466 in my NY & F will barf fluid when sitting longer than a few weeks. I defer to Don Verity as to exactly why and if there is a solution.
Chevrolet's aluminum Powerglide does the same (I have one). It seems the fluid above the hub inside the converter drains back into the case, overfilling pan so that it exits through every orifice, speedo gear seal, dip stick tube seal, shifter cable seal and so forth.
I remember my Dad's garage featured kitty litter and we owned no cats. This leaking stuff may be part and parcel to keeping half century old automobiles and using them occasionally.
