So my car has been making a funny noise for a while now that its coming from the transmission area. it only dose it when in first gear, and downshift. It dose it in first gear when I’m mid way to letting go of the clutch and when I down shift and let go if the clutch. it sounds like a bird or something lol. so I think its the throwout bearing but I’m unsure since l researched and found that throwout bearings make noise when clutch is off and when engage it goes away. That’s not my case though so I don’t know please help:1zhelp:

Perhaps re-explain when it does and when it does not make any noise, I got a little lost in the translation... FYI, IMO better to use terms like - "clutch engaged/disengaged" or "clutch pedal in/out" Also it is not clear when you say when letting go of clutch, so does it only make the noise during the transition of being engaged or disengaged?

If it is a bearing, generally to my knowledge it would be as follows:

Throw-out bearing - would make noise when the clutch pedal is in and clutch is disengaged, as that it when there is a load on this bearing

Pilot bearing or Main shaft bearing - would usually make noise anytime the clutch was engaged, as that is when the main shaft would be spinning.

If only making a noise during transition... well could be a bearing and there is perhaps a little side load on one of the pilot or the main that there isn't when under constant load... Then you say only 1st gear, so perhaps not a bearing at all and is related to the tranny...

So it dose the noise when the clutch is middle getting disengage and I’m in a low gear such as first, or its worse as I’m pulling off my driveway, witch usually is in reverse and it’s a bit uphill. Also it dose it when I’m driving and I down shift anywhere from 3k and up, I will here the noise when letting off clutch. So I hope I made my self more clear this time. O and sorry for saying first gear I forgot to add its even worse when I pull off my driveway in reverse.

Yeah mine is a little noisy in that condition also... not sure what you are running, I have the Stage 3 Action 6 puck setup from DM, seems normal for those to be a little noisy while engaged and in neutral.. not sure but I do know that others I have spoken to that are running something other than stock seem to have some noise...

Pilot will only make noise when the input shaft and engine are turning at different speeds, and main shaft only spins when the car is moving. You might be thinking of the main shaft front support bearing but that would make noise in every gear except for direct

If you hear the noise with trans in neutral and foot barely on the clutch pedal-just past the freeplay- and it goes away when you let go, good chance its a throwout bearing issue

Post up a video, it could just be a motor mount or something loose causing a rattle

Thank you for correction... I meant the input shaft, not main shaft... and yeah again "doh" if the flywheel and input shaft are the same speed the pilot bearing is not doing anything... sorry if I added any confusion...

If I remember right it did not do it when I first got the car back so what I think I'm going to do is new pilot and throw out lol that should fix something.

So you had someone else do the work? That opens a whole list of things it could be...

- Throwout bearing wasn't replaced
- Throwout bearing assembly wasn't properly assembled (fairly common)
- Moving parts weren't lubricated (input shaft, clutch fork, ect)
