Didnt we do the clutch install? I forget... If we did we more than likely replaced the slave which includes the TOB on it. I will have to check the invoice but more than likely we replaced it. We do 100% of the time unless told not to.

Sure did! I don't remember being charged for the slave or the throwout bearing, or seeing it on the invoice, unless it comes with the LS7 kit. Or I could also just not remember at all. The sound has been slowly getting louder, which is the only reason I'm concerned.

Bring it by the shop and I can pin point where it's coming from.

It does, but it's still making the sound after a new transmission. Turns out I needed a new trans for other reasons, but the sound has never went away.

I just had my complete T56 rebuilt, and when I'm downshifting into a LOWER gear only it makes this whining/spinning noise as well like something winding up. It's as soon as you begin to press it into gear it starts making the noise wether the clutch is engaged or not (once in gear), only seems to be 1st and 2nd though (the lower gears). I was looking at the syncronizer's and it appears they have clutch like material on them, and my guess is I'm hearing them spinning or winding up to allow you to downshift into a lower gear? However it does not whine (that i can hear) once actually engaged in gear. When you have your level 3 trans build did they change the second gear? I hear straight cut gears will wine?

You say this happens 'In All Gears', but, have you tried when you're in 4th, 5th or 6th (4th = direct drive, 5th and 6th = not using the first countershaft)? You keep alluding to the transmission, well, the only thing consistent about that with engine rpms is the first countershaft. In 4th, you're not driving through any gears, and in 5th and 6th, you're not driving through that front half of the tranny.

My car exhibits the same sound. Mine seems to be rear diff related. I replaced throw out bearing, slave cylinder, master cylinder, torque tube bushings and bearing, and tranny. Sound was there before and after all the work.
My car is parked for the winter so I cannot experiment with it to answer questions.

Might have to take you up on that one weekend Rick, thanks!

If you rev-match well, you can downshift without making the synchros do the work. The reason you don't hear them during up shifts is that the gear ratios are spaced such that the rpm falling will generally put the counter shaft speed very close to the mainshaft speed, and the hub can fall in much easier.

The transmission was built before it was sent to me, with all new internals. The whine was happening with the old one, and it's happening with the new one as well.
It is extremely noticeable in 1, 2 and 3. 4th and up you can still hear it if you know what to listen for, but not as much. Sorry if I seem to be alluding to the transmission, but I know that isn't the culprit. It happened with the old transmission and it's happening with the new transmission. The old trans was going out on me anyway which is why I had initially assumed the sound was related to that, but with the new one in there (which has resolved all my transmission issues) it's still making the sound so I'm sure it's not that.

I would take a step back, accept that no one can have definitive knowledge without disassembly, and begin troubleshooting again looking at the whole picture.
Or, just take it to Rick, and let him spend an hour to tell you exactly what's happening!

Just a thought.

No offense, but I think you have blinders on when it comes to troubleshooting this. I'm not saying it is the transmission or is not, but I can say for sure that you cannot know that the transmission is fine. No one can know without a doubt that a part is working properly simply because it is new. That is never a good way to diagnose things, especially something like this.

I think your suggestion of taking it to Rick is the best one, and what I might end up going
