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.

 

Sounds just like mainshaft bearing to me. Yes, trans will still operate even though bearing may be totally damaged. I'd suggest pulling trans and replacing all 7 bearing and also install new TO bearing before putting back in car. But from description, definitely sounds like mainshaft bearing is failing.

 

thanks, but i still dont get why its the mainshaft bearing, if the gears are still running when i drive in gear with the clutch in. i figure it will always make a sound when in gear

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.

 

this is typical and just seems to be how the act. i have seen a lot of guys mistake this bearing noise for the TO bearing only to get trans out after selling clutch job and find mainshaft has excessive runout caused by bearing failure. Or worse yet, not catch the bearing failure while trans was out, get trans installed and find out that noise is still there. Very hard to sell to customer, or worse yet tech having to eat the labor to perform same job twice!

Even though you push in clutch, with car still in gear and rolling, there is no load on mainshaft, this is why noise goes away at that time.

But you say that when driving and downshift to lower gear, noise increases in pitch and intensity? Definitely mainshaft bearings.

Also, don't scrimp and only install that bearing. You need to replace all 7 bearings otherwise you'll just be pulling it again later to do same job again.

 

ok. thanks for you input

now, how much is it to replace all the bearings
and how much additional for syncros? i think my 2nd gear syncro is going, i can hear something when i just press it in the 2 pos without the clutch, i hear a spinning sound

 

Si/EX S20/L3 trannys

Input shaft bearing........91002-PSO-003 $17.37
ISB seal ......................91216-PL3-005 $ 3.92
ISB spring washer.........23927-PL3-000 $3.15
ISB spacer washer........23928-PL3-000 $3.59

I just ordered 5 sets from http://www.slhonda.com

I charge locals $80 if the tranny is brought to me, including parts.

 

you think my car will make it to the next autox practice event in feb 7?

or is it too risky?

 

look at this folder..........

you tell me if it is worth risking it........

all because of a bad bearing? yikes!!

man...if i get my clutch done next week, i dont know if i can break in my clutch in time...how long are i supposed to break in the clutch for?

 

you won't get your clutch broke-in in time.

 

about how much would it cost for a mechanic to replace the main bearings in the tranny? if i deliver the car though.

 

3 hours R&R
3 hours for the tranny inspection
1 hour for the ISB

7 hours at $70 a hour = $490 + parts.

Learn to do it yourself.

Sheot, even Bauley could do it himself, with alot of internet help from me!

 

Again. Don't just replace mainshaft bearing. You need to replace all 5 shaft bearings and both final drive carrier bearings. Also need to replace both axle seals and mainshaft front seal.

If you looked at the link to the trans pictures above, you will understand that all bearings should be replaced. Not just one. i have rebuilt literally hundreds of honda trannys and it always seem trannys spread pieces of bearing cage throughout entire trans. These pieces have a tendency to get lodged into other bearing cages, causing premature wear of other bearings if not replaced.

just word to wise...

 

where can i get the final drive gear? maybe i should jsut get that changed aswell, how much ar ethey if they make them?

 

shouldn't need final drive gear. just bearings. unless of course you're talking about changing final drive gear to different gear ratio. but shouldn't need any gears for just replacing bearings.

 

yeah, i was thinking maybe i should change the ratio if its not too expensive and attainable.

 

$500 + labor to chanmge the FD ratio to a SRR unit.

 

wow...didnt expect that coming
what other things besides lsd can i do while the tranny is open?

 

That just sounds like a throw out bearing .. Change that and you should be fine .
It's about 50 bucks

 

im pretty certain its a tranny problem...i was coasting down a hill today in 2nd gear at about 40-50 mph with the clutch in, and i can hear a whine sound in the tranny. the sound's intensity is relative to vehicle speed, if i pull the shifter to neutral, the sound goes away. and the clutch has nothing to do with this situation execpt when the clutch is engaged in gear, the sound just sounds different in the gears assuming its the same problem with a load on the bad bearings.

thanks for all your help guys, i called my mechanic and he said he'll replace the bad bearings and seals for 600+parts, since a new tranny doesnt garauntee a good working tranny
