Who knows though, I might look at the fluid at 10k and thik it looks fine and need to readjust my tentative schedule to every 15k or 20k.

That's WAY overkill. Once every 50k miles would be more than enough. Transmission fluid isn't like engine oil. There's no combustion going on to contaminate it. And there's nothing you're going to see by looking at the fluid that's going to tell you whether it's still good or not.
