Finally got my transmission off, look what I found!

[JStrateger]

A few months ago, my clutch went out on my car when I was driving it especially hard one night after turning up the boost a couple lbs. I babied it to my friends shop and we took off the inspection plate and found pieces of the clutch laying in the tranny; ouch. The clutch had about 4-5k miles on it. Anyhow, I drove it home and just got around to getting the transmission off today and this is what I found:

Looks like my clutch fell apart. Aside from a crappy clutch, anyone have an opinion on what else might have happened? Anyone seen this happen before? Just kind of curious, never had a clutch fall apart like this.

The transmission is being rebuilt and I'm replacing the clutch/flywheel with a ACT2100 combo.

what type of clutch was it

 

[SpawnedX]

That's fine, you can reinstall it.

 

[Tyeler18]

That looks just like both my dsm clutches so far. Only the first one had a spring break out!

It literally looks nearly exactly like the clutch I'm installing in the GSX RIGHT now. Just yours has more meat on it.

I kind of don't want to say this, but you do use the clutch alignment tool right? The right one made for our cars?

^^^^ Please tell us how that works out

Did you make a 1-2-1 shift? That will do it.

 

[Bud92gsx]

Ewwww that sucks dude.. the 1-2-1 shift post made me laugh..

Get me some gorilla glue and some duct tape and I'll have that back together for ya no problems.

 

[Colt4G63 also]

You weren't leaking oil out of the back of your engine or the input shaft of your transmission were you?

 

[VETTE_50_TH]

Still has some life in it

^ yea rear main seal can be a culprit if the clutch was slipping real bad, and if you found oil on the flywheel/clutch area.... what brand was that clutch? also did you make sure the dowel pins were installed when that clutch was put on?

I left this post alone thinking you would get a serious response.
There are plenty of experienced responsible people here who could comment.

The plate and disc look bone stock to me, or a replacement from a local auto parts store.
Which should be fine for a stock horsepower engine, even then, there is a technique to releasing energy into the driveline, to avoid damage.

Releasing energy into a driveline can produce damage in any number of places.
The weakest link in the chain will be the next thing to break.

In racing we load/preload the drive train before launch to keep something
from exploding.

Too much horsepower always presents challenges.

You said you were going to an ACT clutch which is aftermarket and will at least
keep this from happening again.
But what is the next stock part in the driveline that will not be able to handle
the power ? Axle, bearing, gears ?

How much horsepower are you putting out and what mods are there ?

If you are really stock then the disc may simply be a defective unit.
In that case, get real good at dropping the trans.

Ask me how I know.


manny correa - good call on the pins, but the picture shows the dowel pins in the flywheel



pbwuf1 - the alignment tool helps get it installed in the first place.
Once you have trans in and push clutch in, the disc centers up.

 

[T-mun]

i think he meant the dowel pin for the trans mating to engine, not for the flywheel.

 

[98dsmkid]

Perfect example of what happens when you keep dumping the clutch.

 

[morelock]

haha thats not that bad my way in like 15 pieces haha

Did you make a 1-2-1 shift? That will do it.

No but I did go from 4 to 5 then to 4, took it up to almost 6k. When I went to put it in 5th, it wouldn't go and that's when I realized I had a problem.

1-2-1 shift will really cause something like this?

You got the nail on the head, I bought this clutch off ebay about two years ago. I think I paid about 60 shipped for it .

That's what I thought might have been a cause but the inside of the transmission and the rear main is free of oil.

How do you know? (Sorry, had to ask, kind of curious.. seems like you have a tale to tell )

The engine is all stock. I think what it boils down to is crappy equipment. I had the dowel pins on the transmission too, I believe. If not, my ACT clutch kit came with new one from my tranny, which I found to be really awesome. =)

I'm pretty confident that I shouldn't have any transmission problems after this for some time. The transmission is is being rebuilt by jacks, ACT clutch and flywheel going in with new clutch fork/pivot ball and new oem master/slave cylinders.

The most I ever plan to make it about 350 so I think I'll be good with this setup.

Buying a clutch that costs more to ship than it's worth, causes something like this.

I didn't think so, where did the 1-2-1 shift bull come from? Was that supposed to be a joke?

I didn't really expect the clutch to last too long, it was more of a test clutch to see if the transmission even worked and for myself to burn up learning to drive. Someone told me I would burn up my first clutch learning to drive a manual, which is bull also.

I'm really surprised it lasted as long as it did though. If I didn't drive so hard, learn to drive a manual on it and had a dragging clutch for the first month it was in, I would expect this clutch to last quite a bit longer than it did. Not too bad for 60 bucks if you ask me .

I think the brand name was Fort clutch or something.

Are we gonna rename this site "Bored Sarcastic Bastards with DSMs"?

 

[bastarddsm]

No.

I didn't think so, where did the 1-2-1 shift bull come from? Was that supposed to be a joke?

A high rpm downshift can infact cause the facing to come off a clutch disc. Doesn't even have to be a very high RPM, if the facing's integrity is comprimised.

But then again what do I know. It's not like I went faster than most of this board in a n/t with a cheap ebay clutch.

Game over!!

The stage 3 carbon kevlar exedy disc from ebay has been on my gsx for 4 years. maybe you should grab one..
