A little off bmw topic but I've just finished ATF change for our van. It's so much easier to have a dipstick and be Dex III compatible. I did it without dropping the pan and filter change and it took 10 minutes I also used Castrol Import since it's recommended for the original Nissan Matic D fluid which is basically Dex 3 with some boutique friction modifiers.
