If it is not your belt, check your pulleys and tensioner. It also depends on what type of vehicle you have. Sometimes the idler pulley will screech. Hope this helps.

I have a screeching sound in my pick up when it gets up to 2000 rpms. Does not make the noise while idling and starts fine.
I COULD BE THAT IT IS NOT LINED UP, NEEDS SHIMMS
If it is a loud screeching noise it is because they are loose and need to be tightened up, and or they are old and worn out
the clutches in torque converter
more detail required, what are you doing to cause this and where does the noise/ smell come from?
