Good write-up, nice photos as well.

I know that you specified that this procedure is for a 4.4, but it may be worth clarifying the point further as this will be a reference for other X5 owners. As BMW uses transmissions from different manufacturers, the transmission fluid specs are very different. A comment to the effect that "this procedure is very similar for the 3.0, but ensure that you check your transmission for your specific fluid requirements" may save a future 3.0 owner from putting the wrong fluid in.

Good job

Jeff
