There isn't the same risk of disturbing the sediment as there is in the automatic transmission, since there isn't a valve body to worry about.

There is also less reason to change the fluid.

Early X5s used Dexron III, later ones (post 2004) have the x drive and so in that case I would buy replacement fluid from the dealer, it is just simpler.

I can't see the logic to worrying about it at 17,000 miles. If you want to do it (it isn't called for in the maintenance schedule) I suggest you put it on the list for Inspection II at 60,000 miles

Doesn't need to be done until about 60k miles in conjunction with Inspection II
