use a Dextron III or above. I personally like using Type F in my trannys because it gives me a firmer shift but I can't recommend that for you because I don't know what shape your powerglide is in, and I'm going to safely assume it is stock. the newer dextrons carry a higher heat value so they won't gum up in the tranny as easy
