SOURCE: whining noise in engine
Checking the level of the power steering is a good start. The pump is mechanical, driven by the serpentine belt, and cannot be turned off. Your steering may seem normal but if you let it go, low fluid can destroy the pump.

Its the pully. I have a 2006 and had the same issue. It went on for months and I was told it was "normal". Well the bearings on the puly were blown and it broke the belt while I was driving. Cost 20 bucks to fix.

SOURCE: whining when i press gas
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.
