My transmission makes a few different noises and I do not know what is causing them.

First in idle, it just sounds like a metal scraping sound, if I press in the clutch, the sound stays... so I've ruled out the TOB.

The other noise, and the one that frightens me more, when I go in reverse and sometimes first, i hear this LOUD spinning or whirring noise. It doesn't happen when I have the clutch pressed in all the way, or when the clutch is completely let off, but only while I'm depressing the clutch or pressing it in. It happened on my old engine/transmission before I swapped, and that resulted in a blown transmission. Does anyone know what it could be? It doesn't happen all the time, so it's kinda hard to get a video of it happening...

If anyone knows the reason for either sound, I would greatly appreciate your help!

Thanks,
Alex

might be time for a new tranny.. well try changing the fluid see if that helps it takes 80-90 gear oil i forgot how much exactly. i personally used Royal Purple 75-90 gear oil and my tranny is sooooooooooooo smooth but its expensive and i wouldnt use it on tranny that your not sure if its bad or not

The whirring noise...going on a limb here becuase I know next to nothing about bad transmissions, but could it be related to the synchros going out?

Damn, it's going to suck if I need a new tranny.
Bad synchros... wouldn't that make it hard to shift? (I to know nothing about transmissions.)
My transmission holds every gear nice and strong, I just don't understand the noises.
I'm going to try putting in my ACT 10.5lb flywheel, see if that helps. I'll also get them to check the transmission internals while they do that.
Wish me luck :/

metal grinding noise at idle is the pilot bearing. I had it happen to me a while back, my pilot bearing was badly worn.

all manual transmissions make a whinning noise in reverse.

I know what noise you're talking about in reverse, but this isn't that noise. It's a really loud grinding noise. I'll try to get a video/audio clip of it one day.
