    I'm sure ATF would work- but why?

        I remember reading somewhere that mixing ATF and 30W 50/50 does not produce something that is 15W but more like 11-12W, but that's picking nits. Something I do well, especially now that I've quite smoking!

            I used ATF to flush mine as it's thin... I use 15w with progressive springs. Works well for me.

                That pretty much sums it up. Fork oil is formulated for, big surprise, FORKS. ATF is not. Will it work? Of course. Is it worth it to save $3 on your pride and joy? Not to me. Don't buy that fancy coffee on your way to work tomorrow morning. There, you have just saved enough to afford real fork oil...:-D

                BTW, the best thing to flush your forks with is kerosene. When you pull them off to replace bushings (everyone does replace their bushings, don't they? They do wear, after all) and seals, empty the oil and fill part way with kerosene and hand stroke them full length for a minute. Dump out the now disgusting and filthy kerosene. Fill with fresh kerosene and repeat 2-3 times. Presto! Clean forks.

                    that's what is in mine and has been for almost 2 years (dexron-III and 20wt oil) don't use type "F" trans fluid.
