Clutch, throw out bearing related squeel

[dhkemp91]

Hey guys,

My problem is that at take off, i can hear it sometimes while driving and shifting through the gears as well, right before the clutch becomes fully engages there is a squeal every time. Sometimes its a really minor short squeel and others it will squeal nice and loud. Its like something is spinning/grinding on something else and It is really annoying, and i know it isnt supposed to be happening. Is the just the throw out bearing slipping somehow? or what could it be?? here is some background:

I just recently dropped my transmission because it had no 1st gear. I swapped in a transmission that i was under the impression was good with no grinding. Turns out, it grinds in 4th and 5th at OT all day. I have a TT motor in the z and also didnt know before installing the new trans that it has the NA bell housing. But i plan on just dropping the transmission again, and seeing if i cant just take them both to a trans shop and swap the good 1st gear from the NA trans into the TT trans. I also have a stage 5 clutch, should have done this the first time, but i will be getting a reinforced fork and pivot ball. Is there anything else at all that i should upgrade or replace this time around??

Thanks!!!
