Whining noise

Can you make the noise happen with your foot on the brake, trans in gear, and a little throttle? And does it go away in park & neutral? If yes to both questions you probably have a faulty thrust bearing in the torque convertor. If no to both questions you like have a faulty "input drum to pump cover thrust bearing." Either way the problem must be repaired ASAP or when the bearing fails it will be at the worst possible time, like in the middle of an intersection with a firetruck bearing down on you.
