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.

Thanks for the reply!
As far as the fluid goes, I did use Mercon V ATF.
When I changed the fluid, I'm pretty sure I replaced a significant amount. Every time I turned the car on after a change of fluid I turned the wheels to allow the old and new fluid to mix. Which at first brought the fluid back to a brownish color, so I know it was mixing. After about 5 or 6 times of removing the old fluid and putting in new fluid, the color stayed a nice red color. Even now, a day later, the fluid is still a nice red color.
I am convinced it is something else. Should my next step be to replace the pump?
