i think i know what your talking about. I bet the squeal is alot more noticable if you mash the gas and just as it shift you pick your foot off the gas. try that and let me know if its louder. I have that same squeal on the 1-2 shift espically if im messing around and let off the gas just as its shifting. Best thing i can think of is the acc belt is slipping, you know the one that drives everything on the front of the motor..
