Alright this has happened a couple times to me (maybe 3-4 times) when I'm getting on it HARD in first (not launching IE clutch is already engaged) it makes the most horrible noise I've ever heard and does not accelerate.

The noise is like if you were doing 50 in reverse... IE it sounds like it's a straight cut gear all of a sudden...

If I let off the gas it stops and then goes normally...

The clutch is near if not completely at the end of it's life. So I'm thinking it's either that (clutch just stops holding at the higher rpms and the noise is caused by the clutch spinning on the flywheel)

OR

I have a bearing/bearings that are about to go.

but if that were the case it shouldn't stop accelerating right?

Any experienced opinions welcome...

I'm about to do a clutch and flywheel in the car... and I eventually plan on rebuilding the trans... but I'm looking to put that off for a couple months at least...

Clutch slipping could possibly be the no acceleration problem.

Pull the tranny off one weekend and check it out yourself or take it to a transmission place.

I'm hoping it's just the clutch... but it'd have to be down to rivets to sound like it does...

Any other opinions?

def check the clutch but if it does not do it in any other gears or anything else its prob the clutch. Otherwise it could be a drive bearing. I just replaced one in my trans ill try and remember the name and post it up.

How do you figure, you use the clutch in every gear. What engine/tranny? Does it have synchros?

NonovUrbizniz

thanks,

I may just break down and open up the tranny unless the clutch is OBVIOUSLY down to the rivets..

I figure it's happened like 3-4 times so if it was the clutch there'd be signs on the flywheel...

If not I may just open it up as it's not my daily driver anymore... although I'd like to get it back on the road sooner than later and I'll be doing a Cam, Springs, Flywheel, Clutch kit, and headgasket all at once...

Also am going to be upgrading the fronts brakes to prelude SH/ITR calipers.

If it is ONLY in first gear then the problem is most likely related to the gear set...if it were the clutch you'd experience problems in other gears as well.

all8280bcc

sorry i meant to say if it make the noise in other gears it will be a bearing. im at work and its a pain to type when i keep getting pulled away from my copmu.

NonovUrbizniz

see it ONLY happens when it gets up top in first... and I think it might be the clutch because the car doesn't pull that hard in any other gear or RPM range.

But almost all the mechanic's I know have said they think it's the main shaft bearing I think.

xEnderx

IF it was a bearing (main or throwout) you would have problems in gears other than first. If it was a clutch you'd have problems in gears other than first. Think about it man.....thsoe parts are used in every gear. If you are having problems from teh tranny in ONLY one gear and in ONLY one RPM range it HAS to be a prblem in the gear set. Not the diff, not the clutch, and most assuredly NOT the synchro's if its in the top end of the gear.

Not necissarily at all.

The clutch holds to the flywheel... the higher the rpms the higher the force on it. That's why they make dual spring clutches... for extra clamping force the higher the RPM...

In first gear; between the amount of force on the tranny from the engine side (yes I"m aware the engine puts out the same power at the same rpm in any gear) COMBINED with the force applied to the differential end of the trans while getting the car under motion, it's more than possible that it's a problem with either a bearing or a clutch, as they are under MUCH more stress then when in normal use... Granted once they completely fail it will affect all gears/rpm ranges... while they're in the process of failing they may only show symptoms under extreme force.

For example when you clutch is wearing out... it doesn't slip all over the place... it slips at higher RPM or under higher load... then when it goes... it fails all over.

there's no force being fed back through the shifter so I'm next to positive it's not a gear problem.

But who knows.

Thanks for the input though

xEnderx

If you already know the answer and aren't willing to listen to input from others why on earth did you even ask the question?

EK k kay

If it sounds like your car in reverse then it's probably the input shaft bearing. My tranny has that problem. The whine is more distinct in 1st and 2nd gears.

I did listen to your input, however I thought about your input and explained why I thought it was invalid.

By all means refute what I said. The clutch and bearings are under MUCH higher load in 1st gear at high RPM and full acceleration then they are in any other gear. So it's most likely to fail or show signs of failure at that point.

Considering my trans had a history of bearing noise which went away after swapping in Redline MTL, I'm guessing that chowmein is correct.

I'll do the clutch and flywheel and drive it for a while... I'm guessing the new clutch will either eliminate completely (if it's the clutch (which isn't my feeling)) or exaserbate it. At which point I'll open up the tranny.

Thanks for the input guy's and anyone else with an opinion feel free to chime in.

Unfortunately I have already resorted to fluids to save the tranny... Redline MTL and penzoil synchromesh...

It smoothed out for a long time and frankly still is smooth... but I think I'm on the verge of imminent bearing failure.

Which is funny because I switched out the redline because someone on a board told me their tranny shop said the redline can cause premature bearing wear on a honda tranny... I don't know how valid that is or not... and 203k miles is barely pre-mature... but non the less.

Maybe I'll pick up one of the JDM d series trannies with the stock LSD anyone have any experience?

EJ8VTEC

i know u can prolly get one for cheap

NonovUrbizniz

So it's probobly my bearing I guess is the concensus... I'm gunna have to look into what it'd cost to get a JDM LSD Dseries tranny...

Then I'll probobly keep the stocker to rebuild at some point when I have the time.

Anyone know any good sources for the JDM D15b tranny? That's the one right?

Yep, it starts making that helecopter/whine noise in first, then as it gets worse, you hear it in 2nd and 3nd. Its the input shaft bearing.

NonovUrbizniz

Yeah that's what I was afraid of... Looks like I'm in the market for a tranny.

Y dont u get a swap, d series trannys r weak as hell dude... i got a b16 on the way from hmotorsonline, i got a GSR trans w/ LSD with it, i think it will be well worth it!!

NonovUrbizniz

what makes dseries trannies' weak... lots of guys are running more hp then I plan on having with a bone stock d series... maybe an lsd... or final drive... but no gear sets or anything...

A tranny/rebuilding my tranny will cost me like 0-400 bucks at most... A swap will cost me 1200 minimum.
