I don't know AODs so, pardon me if this does not apply:
When I rebuild my WC T5 with Kevlar synchros, it hummed like mini-blower.
With the date scribed on the case, I have to wonder if Kevlar clutch packs were installed during a rebuild. If so, it would explain the whine ( at least, in my head. lol ).
Somebody that knows the AOD better than me might be able to confirm or deny.
After some basic research, I see that it is a common comment among folks who have installed these.

If you want you can call these guys as they have built 100’s if not 1000’s of them.

I can't say this for Ford, but learned this with my Dodge Torqueflight.... Fluid will pump in Neutral, but not in park.... This car sat alot so fluid would drain back and it would not move for a few seconds after a cold start unless I put the car in Neutral during warm up...
