After extended highway speeds (2 hours above 60 mph), an engine whine is noticeable at low speeds (less than 10 mph), neutral, and park. Whine pitch increases with engine speed. Whine disappears when engine is turned off and restarted (whether restart is seconds or minutes later).
Do you
have the same problem?

Hi water taxi,

Thank you for the donation.

Noise problems are always hard to detect, even with the physical car so we can't promise you anything.

Logically engine operations do not produce any whining noise except when lubrications are lacking and if this happens, the engine would fail within a short time. Quite often whining noises are from external components attached to the engine and these includes alternator, power steering pumps, AC compressors, idler bearings and the transmission.

From the symptoms described, the most like source would be the transmission.

Does the noise lessen or disappears when gears are engaged?
When noise is present, is gear up and down shifting smooth? Any jerks?
Does the noise lessens or disappears when you come to a stop? If no, did you try to diagnose which area is it coming from?
After restarting, noise comes back only after another long drive?

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.

Thanks
