To fix mine I had to flush the fluid and change the pump. In truth I don't think the pump was bad, most likely the reservoir screen was dirty. I changed the fluid first and things got a little better and sometimes sounded normal once the engine was warm, but in the morning or after the car had sat, you still had the squeal. On changing the pump, it took about a day for everything to sound normal.

Since then, I have also added some seafoam trans tune to the PS fluid. I plan to leave it a week or two and flush the fluid again. This is the method I followed.

Another thought... Did you bleed it correctly?
Also, was it a rebuilt from somewhere like an AutoZone? If so I had the same problem in the past. Took the third pump to stop the whining sound. Did a quick search and found it's a common problem with rebuilt pumps.
