Fluid full? How many miles since lat tranny fluid flush? Let's look at the easy stuff first.

You sure you have the gaskets sealed and is the dip stick pushed in all the way?

Does the whine change with the throttle? Does the whine go away in park and neutral? Can you change the whine with the throttle in drive with your foot on the brake? There may be crap in the governor or the throttle pressure system might be sticking.
