It depends on who you talk to.
Either the dealer, the transmission manufacturer, or some experienced BMW tech, you will always get mixed answers/ opinions when to replace the ATF and whether or not to replace it.
Some say 60k miles, some say 80 miles.... and after you pass a certain mileage, it becomes unsafe to replace the ATF.....
IMO, it is all a wife's tale...
It's up to you, what you want to do to form an educated solution from the experiences and info. flowing around.

I would buy 8 or 9 quarts of ATF.
It depends if you are going to drain the ATF again shortly after...
Call the dealer and a get a price quote.

Pentosin is the OEM ATF.

PM me your last 7 of your VIN, and I will see if I can get the VIN decoder to work.
