1. i hear a light sound in neutral, engine running and not moving and clutch out
i can only hear the sound when i listen for it (radio off)
2. the sound stops when i push the clutch in
3. when i drive, i hear a whirr sound between 1k-4krpm, loudest 1st gear, and
gets quieter 2nd and 3rd and on its hardly hear-able
4. when im crusing; in any gear with the clutch in, there is no sound
5 when cruising; with the clutch out and in gear, the lower the gear the louder
the whirr, but not as loud as actually accelerating
6. when im cruising (50mph); in 2nd or 3rd (louder in lower gears still),
and with the clutch in and gradually letting go the clutch
(so the rpm climbs to vehiclespeed) the car makes a high pitched
whine, not loud, but very noticable untill the rpms match vehicle speed

ok...so some people say its the throw out bearing, some would say the input shaft bearing...im thinking its not the input shaft cause with the car moving in gear with the clutch in, the gears are all moving. but it doesnt make sense to me to be the TObearing, cause it should make more noise with the clutch in if it were bad?

I checked the tranny fluid, and it was still orange, no particles came out or anything, seems like healthy fluid, and it was topped off too, no leaks anywhere.

 

Input Shaft Bearing

What happens if you don't fix it soon:








The ISB will get chewed up and thrown all over the tranny...destroying it and locking it up. Tom (B18C5-EH2) said he drove around for a few months on a bad one and he was locked out of gears (destroyed tranny).

 

thanks, but i still dont get why its the input shaft if the gears are running and no noise comes from it when im moving in gear with the clutch in.

my oil looked really good though, like i just put new oil in there.

and the sound is nothing related to a clicking, just more like a light grrr sound

 

wow, this forum moves fast

 

I have a similiar sound in my CX. I'm planning on putting in a GSR within the month if all goes well so hopefully it will last. Cross your fingers.

 

SOunds like a normal throw out bearing problem, I have encountered this on numerous other cars, but never a honda, but there is a first for everything.

Because the input shaft stops spinning when you press the clutch in dude...

Mine started out as a light grrr sound...then it becomes clicking...next thing you know, your tranny is dead...

This is a common problem among hondas...if you want the noise to stop...open up your tranny and spin the bearing, you'll hear it clicking and that means its bad...no one is going to tell you a different answer...I hear these same symptoms at least three times a week and I tell everyone its the ISB, and they all replace it and its stops.

 

friend had a bad input shaft bearing. I'm in the same situation right now. not lookin forward taking the tranny apart.

Oh its so much fun!!!!

Just make sure you dont bend the interlock like I did

 

just trying to get a better understanding on how the tranny works...i thought when you're moving in any gear, clutch in or out, all the gears turn in the tranny?

 

http://www.howstuffworks.com look up transmission.

yes, the gears / main shaft, counter shaft are always moving in there, as long as the engine is turning. that link will explain everything very well.

With clutch pedal on floor, the shafts in the tranny stop spinning. If the noise stops, then it is a bearing INSIDE the tranny.</TD></TR></TABLE>

All of you...search "input shaft bearing" you will find 10 threads of the same symptoms. For it to be a throwout bearing, the noise would be when you press the clutch in, not when the clutch is let out

 

Thanks for the writeup im sure it will come in handy. Did you have to use any special tools (like pullers)? I have all the tools necessary to do a clutch job. but ive never done anything inside the tranny casing.

no, im saying, every thing in the transmission turns when in gear and the car is moving, not the engine. the clutch is the link between the tranny and the flywheel when the car is already moving, thus revmatching to not use the syncros...so im thinking the gears in the tranny will make noise regardless the clutch being in or out..but in my case its only when the clutch is out.

ive looked at all the threads...some peopole say its the TO bearing, and it supresses the sound when there is load on the bearing, some people say its the main shaft bearing. i dont abuse my clutch, but i do autox. the oil was still orange.

im wondering why the mainshaft bearing would go out cause there is tranny oil constantly lubing it, where as the TO bearing only gets the lube you initially put on it.

thanks for the replies, greatly appreciated...btw, how much extra is it usually to crack open the tranny? i might as well get my clutch changed

 

you said something about the fluid looking good and still orange. honda MTF and/or 10w30 motor oil are not orange. 80w90 and 75w90 can be orange. what the hell kind of fluid are you putting in your tranny? (you're supposed to use Honda MTF, 10w30 motor oil, or even sometimes GM Synchromesh)

 

sounds like an input shaft or another mainshaft bearing. sorry if i am the 33rd person posting this response. but that is a very common problem.

 

i bought my car used...so i dont knwo what oil they used, but the new oil i put in there was orange too, 10w-30 as well

man...sucks to have a common problem that involves splitting the tranny...i thought hondas were made better than that. i only have 113k miles


oh yeah, can someone tell me if the tranny doesnt spin or does spin while in gear when the car is moving? cause thats how in understand a tranny works

Okay...replace the throwout bearing and when your tranny is still clicking dont come crying to me

Because it was a flawed design in the first place

Bearing from '92 (notice the plastic ring holding the ball bearings in):


New, Improved Bearing (notice the plastic ring has been replaced by a stronger metal piece its in the upper left of the picture):

yeah i know that when you disegage the clutch the tranny stops, i was a little drunk last night when i posted that. 1.00 yuengling pints + me = misinformation

to the thread starter: it is your input shaft bearing. just fix it, and quit pissing around.

LOL I was like "jwn7 is never wrong what the hell is going on!??!" heh

 

Input Shaft Bearing. If you don't like our correct answer, fix it your way and make another post about how we're all wrong.

We'll be waiting .

 

ISB didnt fix my ****. Neither did a new needle bearing. Or a new TO bearing. Blah! But I suggest you replace ALL bearings...or like Dustin said, do a bearing spin check. That'd be ur best bet. I had to take out my tranny TWICE...and still didnt fix it after replacin a couple bearings at a time...dont do what I did...the car's gone now anyhow.

Which was it? My friend had one of the top two bearings on the mainshaft fail

 

Lets say the ISB fails, ruining the tranny. Is the differential still removeable and useable?

 

This is what happened when mine went- SOrry about the huge pics
