Here's my symptoms: when under load, I hear a distinct rattling noise from around 3000-4000 rpm. No noise before or after that and I don't hear any noise at idle. The noise goes away when I put light pressure on the clutch pedal. I know there's a TSB for the input shaft on the 04's, but that's for a noise at idle.

Any input is greatly appriciated. I dread going to the dealer, but if it gets any worse I'll probably have to have them diagnose it and go from there. My luck it won't be a warranty covered issue.

 

well, I read right after you posted it, and don't have any idea. I am posting now because I can probably at least tell you a little bit of info to help you diagnose further. If it is a rattling sound and it only happens (noticeably) during certain RPMs thats because you are at the harmonic vibration region of the parts being rattled and the moving parts causing it to rattle. In other words, it is rattling at all times but you don't notice, and when you get to 3000 RPM it begins to rattle in a pattern very violently, and stops again at 4000 RPM. I don't know what it could be, but maybe this will help. sorry about your problem man.

how many miles do you have on the car now? is your clutch showing any signs of wear other than being closely related to your noise? has there been a change in pressure in the pedal at all? Is the transmission louder sitting in your driveway with the clutch disengaged in neutral than it was before?

Car is at 40,000 miles and sounds normal at idle. Clutch chatters a bit when it's cold, but that's normal. Once in a rare while, the clutch will grab early, but then returns to normal. Pedal pressure is the same.

 

I have a similar problem.. yet engine related i think? When i'm not in gear and the clutch isn't pushed down, there is a clicking sound coming from the engine (similar to the "four-banger click" some people call our engine noises) but when i engage the clutch (with or without being in gear) the clicking goes away.. any ideas?

 

sounds like you need to take it to a mechanic and have them diagnose it otter. the service techs have probably seen or heard of this problem before, and of course would actually be able to see and hear what is going on, which we can not. Sorry I can't help more, have you pmed any gurus?

 

That sounds like either your throwout bearing or the input shaft that's out in one of our TSB's.

As for my problem, I haven't yet taken a good hard look at it myself to find it. I'd rather avoid the dealership if at all possible.

 

I don't know what your willing to go through to avoid the dealer, but thats a pretty closed system. I'm sure you know that, so I hope you find something minor that you can fix. good luck, and let us know what happens!

 

So you think i need to bring it back to the dealer? Cause personally the car drives fine for the most part.. sometimes i do get the sense that i have to give the car a lil more gas than normal to get it into gear (1st) but i thought that mighta been normal... All occasions of the "extra gas" has been when the car is warmed up and has been driven for a while too... Also will the throwout bearing/input shaft being out damage the car?

 

Any transmission noise is BAD. Input shaft vibrating could cause your transmisson to come apart. Throwout bearing is less critical, but still should not be ignored.

 

Well then i guess my car is going BACK to the dealership again... haha

 

I drove your car. To me it feels like a problem with engagement. As far as that you have done everything you can to make the clutch slave/master cylinder work to their fullest extent. I doubt you have much clutch wear. Although because of it being intermittent it is possible your flywheel is somewhat warped from heat cycling. When everything is constant it has to point to something.

The next thing is that Syncroshift. Even though it makes things smoother it is very possible that the thicker lube is needed to help things in the transmission mate properly. If it doesn't have lubcrication something is going to sound rough. Also at 3-4k RPM is the MIVEC engagment point so a Ralliart seems more torque in this range and this could cause unexpected wear that is hard to beat down.

How repeatable are the noices with different drivers?

 

I'm noticing that the noise only occurs when the car is up to temp. More and more I'm thinking it's not a trans specific problem, but something still isn't quite right. Maybe I'll try running the OEM fluid for a bit, as well, to see if that changes anything.

Nobody else ever drives my car. You drove it once, and so did Zack, that's it.

 

Well my car does it when its up to temp as well, also does it really noticable if i push the car harder than normal. I talked to a mechanic near my house and he said it was the throw out bearing most likely, also told me to take my Short shifter/bushings out before i bring the car back in, cause i don't want to give them any possible excuses...

Edit:
what would cause a throwout bearing to cause trouble? I mean i don't drive the car that hard, and i know how to drive manual pretty well so go figure... I learned how to downshift/drive stick on my old mr2 for 2 years so i mean i'd consider myself a good driver and so have others...

 

Big chances are that it is not the TO bearing. Plus a TO is like having a bad wheel bearing, as you have more speed/RPM it makes more noise. PLus if you were say at 4k RPM and you put the clutch in does it still make the noise?

 

This addressing otter?
