Is this thing loud or is it me? FIXED (?)

My 2011 X5 35i drive line noise seems loud. Loud meaning what sounds like a whining noise from the transmission. The noise changes pitch/frequency with engine rpm and is more noticeable at low (under 10 mph) speeds. It seems to shift fine, no codes or CEL lamps are lit, the trans oil temp is lower than the engine oil temp. I did a fluid drain and fill of approximately 4.5 liters before I do the complete filter pan change. The noise is no different, which is actually a relief, but it just seems louder than it should be, but i have no other reference. Anyone else?
