Reading ATF dipstick

[davew833]

Sorry for the dumb question, but I don't have an owner's manual and I'm having trouble reading my ATF dipstick. It has three holes or marks about the same distance apart (1/2" or so) from bottom up. Can someone explain the marks to me? How much fluid needs to be added to go from one mark to the next one up? Is the top mark "full" or is it "you added too much, dummy." I've always had a little trouble reading ATF dipsticks because ATF doesn't seem to stick to it the way oil does to an oil dipstick. Any help is appreciated.
