Your PS should be filled with ATF. I use synthetic ATF and do not have any screeching sound.

Yes, ATF is correct, have you checked the level yet? There might have been an airbubble that freed up and now you are low on fluid.
FYI, there is generally noise in any vehicle when you turn the steering all the way to full lock and hold it there. Is it that same sound, but just louder than normal?

Flushing and replacing the Dextron III in the system might fix your screeching problem.

Dexron III is ATF and is what is recommended. I've mixed brands and types of ATF in other cars PS systems before without any noise problems though. (Dexron 3, 4, Dexron/Mercon)
If the fluid isn't low, then an actual flush of ATF through the system would be the next step. Perhaps some dirt/debris got into the system during the repair?

make sure you dont overfill the oil, there is a definite level on the dipstick which you can see if its overfilled or underfilled. I would think overfilled would give you some problems too.
FWIW I used the Mobil 1 ATF and have had great results with just about 4-5 fluid exchanges with a turkey baster, exchanged about a quart of fresh fluid.

Overfilling won't cause any mechanical problems, but could cause a mess as that extra space is to allow for heat expansion and room to slosh around while driving. The cap has vents in it and fluid will leak from there if it is too full.
