A common cause of a whining or buzzing type noise when not in gear (neutral and park) is a WORN PUMP in the transmission. How many miles are on the car??
A noisy pump is just noisy and won't cause a breakdown until it becomes MUCH louder. If the noise is not that loud at this point, just keep driving it for now, and chalk it up to normal wear & tear. But DOOO make sure your transmission fluid is topped off. The amount of fluid between the LOW and FULL marks is about one pint. DON'T overfill OR allow it to get below the LOW mark. Transmissions are VERY fluid-level-sensitive.
Because the whine is still happening at high speed when your in neutral and low rpms it should not be engine or tranny related. I would start looking at wheel related issues. Hubs probably.
One wheel turning faster than the other is normal if both wheels are off the ground. If one wheel is dragging when the other wheel is on the ground, it could be brakes or a wheel hub bearing. Usually if the noise happens on right turns, the left hub bearing is failing, and vice versa.
If the noise happens when car is in park and you rev it to about 1500rpm's then its thebearing in the oil pump of the torque converter.It should make noise all the time even in park ideling. You may need a rebuild transmission. Have the vehicle checked out at a transmission repair shop
normally, the only part of your automatic transmission that will make a whining noise is the pump. it usually whines when iether the fluid is low or more commonly when the transmission oil filter is getting plugged up.
the power steering pump will also make a whining noise too.
turn the wheel all the way to the right and hold steady pressure against the stop. this puts maximum force on the power steering pump and, if the power steering pump is the one making the whine, it will change the sound of it. (usually louder).
if the trans pump is making the whine noise, it should sound different in neutral compared to drive. this test will really only work if it make the noise without the vehicle moving. if it wont do it at idle hold the rpms at 2000 or so.
if you decide the noise is coming from the transmission, and the transmission filter has not been replaced (assuming you installed a used transmission), replace the filter by removing the oil pan.
oh and also, if it is the power steering pump you should be able to make it make the whining noise while the vehicle is stationary. if it wont make noise unless its moving its not the power steering pump.
Have you crawled under the vehicle and personally inspected your exhaust line from manifold to tail pipe? The roaring sound usually occur when there is a hole in the exhaust line. I had it happen to my forester before. A hole half the size of a dime made my subaru sound like my old 74 chevy pickup.
