Power Steering Whine After Fluid Change - '00 GT

Hey everyone!

I have a 2000 GT with 190k miles and a 5-speed tranny. So I have been having an issue with a whine coming from my engine bay. The whine only happens in the winter months on a cold start up. I did some reading and found out that it could be the fluid in the power steering. So I checked the fluid and it was black so I decided to replace it yesterday with Mercon ATF. I did a complete flush by lifting the front wheels off the ground, using a turkey baster to remove all the old fluid, filled it with new fluid, turned the wheels mixing the old and new fluid, and repeating until it was back to a normal color.
I turned the car on this morning to find that the whine is still there. My question is: could it be the actual power steering pump that has to be replaced?
I took a video so you guys could hear the sound.

it could very well be the pump. only one thing really causes that noise and thats air in the power steering system, and trust me, they can be a serious SOB to bleed. occasionally when air has been in the system and does damage the pump the bearings in the pump can make a similar noise, and thats when you know you need to replace the pump.

it could also be that you just have a lot of bleeding to do still.. in which case replacing the pump would be counter productive.
