That's odd. I've always changed auto trans fluid every 30k and told family to do the same. Granted I've only owned one auto car until now. Now both BMW's are autos.

I was thinking I would do the change every 30k, now I'm thinking 40k if people are really going 50, 75 or 100k on their fluids. But do them both before the warranty is over so if something happens its covered.
