Mein Auto: 2004 BMW X3 3.0 Auto Tran
So even if the factory used DIII fluid, I should just go ahead and put xDrive fluid?

I will keep the factor that you mentioned about the differentials... unfortunately, I prob won't be getting to that anytime soon. I'll do the coolant expansion tank, and then the transfer fluid change soon and we'll see how it goes from there.

Assuming the car gives me no problems, I will start saving up to do a full cooling system upgrade by the summer which is right where I should be hitting 100K and I'll also try to take care of other fluids... but I am death scared to touch the tranny, especially if it's working fine.
