Can you describe this whine?

Is it mostly manifest under acceleration and in the higher gears?

Swepco and Redline tend to be thinner oils which will usually increase the whine.
I would really recommend repairing the whine anyway before it becomes a roar and a boom !

It is more like low pitch humming than whining. It happens in acceleration only at 30 mph and it comes back at 55 mph and sometimes at 60 mph before it phase out.
