I'm looking a purchasing a 2006 BMW X5 3.0i and found out that the transmission fluid (by dealer) is not suggested until the vehicle surpasses 100k. They also state that the vehicle will let me know when fluid change is needed by dashboard warning light illumination. That seem quite boastful especially if it includes the filter.
My questions are:
How can a transmission survive 100k miles with no filter change and still perform?
How can BMW do this while other vehicles must change fluids and filters at preordained intervals?
