My trans always made the faint "rattling" noise in neutral which seems to be common for those with 6-speeds, but then about 700 miles ago I installed a spec stage 3 clutch (pressure plate and TO bearing were used, but disk was new) and at first there was no difference, but as I drove it more, the neutral rattle got much louder. I'm wondering if you think this is normal or could it be a problem?

 

interested on the answer also

 

Also I should add that the pilot bearing wasn't changed out with the clutch in case that could be a problem.

 

Sounds like a throwout bearing ( is that a pilot bearing? ) lol....well I heard that rattle on mine then it went out and was the "throwout bearing" as I know it---

 

Well actually I replaced the TO bearing when replacing the clutch (it's the part that is mounted on the fingers of the pressure plate). Reason why I mention the pilot bearing (it's the part that's mounted on the rear of the crank and supports the trans input shaft) is because when I do searches, that's the part that most people claim causes the "whirring" in neutral with the clutch pedal out, but the noise goes away when the pedal is pushed in. Some people recommend changing that part for a new bearing or bronze bushing when changing the clutch, but I didn't do that. Just wondering if it could cause problems.

 

I wouldnt worry. They all seem to make the noise. Mine got louder after one clutch install, quieter after the next. Never any problems.
