I read many posts about owners that have heard a "Rattle" from the clutch or transmission.
I have a 1992 Stealth TT with 131000 miles. I think it still has the original transmission. It shifts fine, even in second gear and reverse but I have the "rattle" noise that gets fairly loud when the car is in neutral with no foot on the clutch. It is quite noticeable when standing by the front right wheel (trans. side). If I push the clutch in ALL THE WAY the noise disappears completely. I checked out this "noise" with another Stealth TT owner in my area and his car does the same thing - in neutral without foot on clutch, some rattling but push in the clutch and noise goes away. My rattle is much LOUDER than his car but they both have it (his car has approx. same mileage).
I bought this car in California, Dec 2009 and drove it about 1500 miles to get home. The noise was very faint when I bought the car but it started to get louder as I got closer to home (in neutral, idling). I thought it was tranny damage at first BUT I drained the oil, found no filings,shavings, etc. I then changed the trans. oil to GM SyncroMesh and it still has the same rattle.
I purchased a used JDM trans with about 40,000 miles and I was planning to to install it, but like I said, my trans. shifts FINE with NO GRINDING, so I am a little reluctant to fix something that might not be broken...!!
Is this noise just a throw out bearing or something more serious?
I had the same thing, Clutch out in neutral sounded like i had a bag of rocks for a throw out.. turns out my tranny was bone dry on gear lube. long story short. By re-adding fluid I blew out 2nd gear. double check your fluid levels. these trannys like to be totally full :/
how long ago was it's clutch replaced? if you don't know the last time it's been replaced.. honestly if you say it shifts fine and the fluid levels are fine. Buy up a nice stage 2 or 3 clutch. and replace the TOB while replacing the clutch. and it think everything will be fine. but even if you plan on swapping in the JDM tranny you should buy a new clutch. it's probably original and at 40,000mi it should probably be replaced before you put it in.
had my car since 2001. had new tranny, still made noise, 3rd new clutch ,new tob, new fork, new fulcrum ball, sill makes the noise. you might find 1 in 50 owners that claim thiers never makes the noise, every memeber in ak's has the noise. you just have to keep clutch depressed at the bank and fast food lines

When the TOB is not engaged to the clutch, it's just sitting on the input shaft bearing assembly. It has no reason to rattle unless what it's sitting on is rattling. I would say it's more likely your input shaft bearing causing the noise.
But it is fairly common because it more often than not goes without being properly diagnosed. It's also pretty much harmless, aside from being annoying.
I'm pretty sure the input shaft bearings are extremely difficult to get a hold of these days. There are a couple members here who may be able to help you get one though. Let me do some research and see who they are.
Option 1 is very do-able, it's nothing that absolutely NEEDS to be adressed.
I will say this, I had this rattle before my build. Now, post-build, I don't have the rattle. During the build I disassembled the transmission and had the input shaft bearing pressed out and eventually pressed back in. This may have cured what was causing the rattle.
I did replace the TOB at the same time, so which fixed the noise can't be said for certain. However, the rattle persisted when the old TOB was originally installed. So the TOB was likely not the fix, as replacing it didn't fix it previously.
the noise is actually the clutch hub center inside the disk. there is a plate inside the disk that is up against the springs. pick up a worn disk and shake it.. thats the noise.
alot of new aftermarket clutchs make it most worn clutches do also. the latest mitsu disk should be quiet. there was a tsb on it in the late 90s for an updated disk.
so, you can just leave it alone. it wont cause a problem
