Noise from the Transmission/Clutch

mrsyeltzin · 02-24-2009, 10:12 PM

I've recently discovered a new noise coming from my FA5. I've got 42k on the clock, just had the transmission fluid changed at the dealer about 1000 miles ago and now I'm hearing this humming noise coming from the transmission when engaging the clutch.

Background: I discovered it yesterday, while in pretty heavy traffic, and figured it could be from all the shifting (mostly 1-2, stop, repeat). I didn't think much of it until I drove the car again today and heard the same noise. It's sometimes not noticeable and sometimes loud. I will only hear the hum in the first gear I'm engaging from a stop. I think that statement is important because I will hear it in first, not in any other gear until I try to launch from a stop in another gear. I think the humming noise is coming from when the transmission is originally being engaged to move the vehicle.

As a test, I pulled the e-brake and slowly released the clutch in 1st, 2nd, 3rd, and 4th gear. I heard the humming in all the gears, and if I kept the clutch right at the beginning of the engagement point I could keep the humming consistent (I didn't do this for more than a few seconds sustained).

I'm wondering what part of the transmission could be making this noise, and how serious it is? Could it be related to the fluid change? I've never heard it before, ever.

A quick google search brought this page up, which might be what I'm seeing:

Transmission Humming noise from clutch when cold - Civinfo

I also posted this on vtec.net and didn't get anything.

Thanks.

EDIT: i also noticed the noise doesn't always occur, but its not related to how cold or warm the car is. it happens in reverse too. i cant hear it when stopped, it doesnt seem to be RPM dependant. it wouldnt be a motor mount or brake because i can be stationary and making the sound. baffling.

Perhaps it could be the throw out bearing?

mrsyeltzin · 02-24-2009, 10:28 PM

perhaps, but i dont know. wouldn't it sound all the time in all gears? the odd part about this is that it's ONLY in the first gear selected to get the vehicle moving. and it's only sometimes...i'd think that if it was the throwout bearing that it would be noticable during every shift. ive tried, while driving, to just slip the clutch and see what happens and i cannot get the sound to repeat.

***db8typer*** · 02-24-2009, 10:32 PM

Are you sure the dealer put enough if any fluid back into the transmission?

mrsyeltzin · 02-24-2009, 10:38 PM

The scary thing is, i really don't. i don't have the ability to check it right now nor am i close to the dealer that did the service for the next few weeks. I've driven probably 500-1000 miles since this was done, so if there isn't enough fluid, the damage is most likely done.

everything else about the transmission feels fine though, and I've been on some long highway trips with no issues whatsoever.

markturbo · 03-03-2009, 09:45 AM

My 07 Si is doing the same thing.

When the car is under load, for example, say you're going up a hill in stop and go traffic, you come to a stop and then when you go to start again while in first gear letting the clutch out it will make a loud hum sound, if you have to ride the clutch for a few seconds it will continue to hum...even become louder. But if you're able to pull away quickly without having to ride the clutch then it doesn't make the sound.

I made an apointment to bring my car in tomorrow.

dmei2 · 03-03-2009, 10:21 AM

My 08 si did the same noise, i heard it when clutch out going to stop, also 1 gear to sec gear.

cool - let us know what happens. i noticed that my car seemed to have stopped making the noise yesterday, so I'm going to hold off on visiting the dealer (I was going to go today).

markturbo · 03-06-2009, 07:37 AM

Dealer took it out for a test drive, and of course they say they couldn't hear it. So I pick up the car and as I drive away it makes the noise, so I go right back into the dealer and tell them I want the tech to come out and listen to it as I can get it to make the noise at will.

So the tech (It's the tech that replaced the 3rd gear, but this noise is unrelated as it was making the noise before the 3rd gear fix.) comes out and I'm able to make the car make the sound, but then it stopped and I couldn't get it do it again. The tech made it sound like it was a viberation coming from somewhere under the hood and that it didn't sound like it was an internal sound. I strongly diss-agree with him, if you guys heard it you would know what i mean.

The car is going in next week anyway because the sway-bar end links are shot, the tech said he will look at the clutch noise then.

I'm so frustrated right now because the car is still making the clutch noise, the rear sway bar end links are shot and noisy as hell, and I swear the front end of the car feels off since they had it for a test drive and it sounds like a bushing or something is loose in the front now...this car is stressing me out, I didn't think i was driving an old clunker, it's an 07 Si with 46,000km on it.

My car has been doing the same thing for a while now... I've noticed that if the clutch is held in, humming goes away... It comes back when i release it in 1st gear and sometimes in second gear... The noise really isn't normal and everyone that get's into my car notices it... The car itself feels fine, nothing seems to be abnormal, besides the noise... 06 ex with about 70 000 km... I'll try taking it to the dealer this week

markturbo · 03-16-2009, 01:37 PM

Well I had mine back to the dealer and they were trying to pin point where the noise is coming from, they say it sounds like it's coming from the serpintine belt and tensioner area, so they're going to replace both.

To me it doesn't sound like a belt noise, but hey, I'm just happy they're working on it and are trying to solve the problem. The dealer is doing the work tomorrow, I'll update after I get the car back.

stealth · 03-16-2009, 01:39 PM

Hmmm... I'll mention that when I bring it in! Mine also does it maybe 25% of the time while idling at a stop, then it goes away when i press the clutch in then restarts once the gear is engaged in 1st and 2nd... It's pretty much making the noise non stop now!

markturbo · 03-16-2009, 01:43 PM

Mine only does it when you let the clutch out slowly matched with a low rpm while moving the car from a stop in first gear.

They said the noise sounds like it's coming from the passenger side of the engine bay.

stealth · 03-16-2009, 02:30 PM

I'm at the dealership right now getting it checked out I'll let you know how it goes...

stealth · 03-16-2009, 02:50 PM

We took the car for a spin and he heard the noise right away... Said it might be tranny related... The clutch oil level was at minimum he said it might be an issue... Pulled the car in the garage to get it checked out...

markturbo · 03-16-2009, 03:04 PM

Let us know what they find. I wonder if it's the same noise I'm having, wonder if we could have our dealers contact each other to see if it's the same noise. Only thing is, our Civics are different models.

stealth · 03-16-2009, 03:31 PM

Well apparently the bearings in the transmission are blown and so I need new bearings and new gears... All covered under warranty, I'll be taking my car in 2moro to get it fixed and I should have it back by Wednesday!

JoeFromPA · 03-16-2009, 04:18 PM

In any other car, the description given (hums when clutch pedal is operated, all gears, is not dependant upon speed) I'd say throwout bearing.

On this car, with this history of trans problems, I'll go with could be anything

a1rfreshener · 03-17-2009, 11:23 PM

its clutch chatter guys..... u get it from wear and tear. and engines as well
we dont have alot of torqe so its the engine struggling as well. the humming is the engine trying too keep it self going and not stalling.rest easy.... but might as well have honda check it is a plus+

stealth · 03-19-2009, 08:55 PM

No no it was not regular wear and tear, I'm telling you, if I could have gotten you an audio clip you would clearly hear that something is wrong... I don't know about the other people but mine certainly was... It was more of a grind/growl/purr than a hum really... The Honda tech heard it right away we didn't even leave the dealership...

Just got my car back, all was done under warranty and now the noise is completely gone, feels as good as new! Glad it was taken care of!
