Screech when shifting

Just wondering if anyone has experienced the following?
My 5.4L is producing a screech sound at the shift points that I originally presumed was the belt, or at least it sounds exactly like a belt slip.
And b/c I thought it was the belt I didn't (haven't) really panicked, I just planned on replacing it whenever I got the chance.
It only tends to do this if I've got my foot into it and shifts at higher RPM's, generally through the first three gears.
Now before I go ahead and replace a belt that I just replaced last summer, I'm wondering if a serpentine belt would actually squawk like that???
I thought I would check here and see if anyone else has had this issue and or discovered its origin?
Or if anyone thinks it could be a tranny issue?
Also, my exhaust is a little too loud to really hear and pin point the location.
Thank you in advance for the heads up

Belt. As a matter of fact, the police crown Vic's did it so bad, they put a one way clutch on the alternator pulley.

Good to know, easy fix for a change :D
If anyone cares, the belt I put on to replace the OEM was a 'Gates' premium
Going back to the Goodyear gatorback I've used on other vehicles and see if that's the fix
Thanks again

Any annoying screech in a truck can usually be fixed by getting a divorce.

I did this one just because I couldn't stand to see 2299 posts.

That is a costly fix.

Check the idler pully. If the spring is weak, the new belt will talk to you

If the belt is worn cracking and glossy.. I've seen them squawk as well.
