In reply to your response questions"
All fluids checked and verified within high/low limits. I am an experienced mechanic and know how to checl.
Engine oil life at 75%.
Does the noise lessen or disappears when gears are engaged?
As stated in initial query, whine is same in all auto trans positions (P, R, N, D)
When noise is present, is gear up and down shifting smooth? -YES
Any jerks? - NO
Does the noise lessens or disappears when you come to a stop? NO
If no, did you try to diagnose which area is it coming from? Yes, appears to emanate from front of vehicle, I suspect a drive belt
After restarting, noise comes back only after another long drive? Same conditions as noted in initial query - prolonged highway speeds, and whine only heard below 5 or 10 mph, any higher speed and whine is obscured by road noise.
