Think with your dipstick, Jimmy.
My wife's Saturn doesn't have a transmission fluid dipstick. The fill procedure is the same as filling a differential... fill until it comes back out the plug hole. Of course, it's difficult to do this when you're filling from the top of the case, and the plug hole is fairly inconspicuously placed on the lower section of the transaxle.
And there is no sensor to tell me about the fluid level, either.
