Lots of folks have mixed ATF into diesel fuel for years; some insist that only Type F ATF is the one to use. I've never heard of anyone mixing ATF into gasoline 'til now.
Anyway, don't do it. ATF is not intended to be burned, and it won't burn as cleanly as you wish. For those who really can't stop themselves from adding an oil product to their fuel, use 2-cycle oil. It's made to burn cleanly.
A far, far better idea is to buy a diesel or gasoline fuel additive from Tim Mills. Neutra or Soy Ultra for gasoline, and Neutra, Diesel Treat 2000, or Soy Shield for diesel.
