CA drivetrain issue now i love it!!!

[DRIFTBOI240]

So i fixed my overboosting issue with the wastegate and it was a boost leak by the turbo output which is now replaced with new gasket and new hot pipe setup.

Now as of yesterday i was chillin cruisin out into the main street with my lil brother and my car doesn't wanna go anywhere. This happened when i shifted going from third to fourth, took my foot off the clutch and nothing. So i downed to third since i assumed my fourth went out and nothing. lucky me i rolled into a parking lot when there wasn't any cars on the street

So i wasn't pushing it nor have i been for a while, very moderate driving and it didn't make anykind of noises when i happened. It idles fine and i can go into any gear without the car going anywhere(even reverse). My setup for the drivetrain is a Spec clutch and welded diff. that's it i guess ohh and it goes right into anygear without having to press the clutch.

Any ideas would help please. Due to me having to work i haven't messed with it since but wanna know what i could expect when i take it apart.

Thanks

No crazy noises preceding this I assume? You can shift with the engine running without the clutch being engaged?

Pull the transmission, the pressure plate has likely failed and is not holding the clutch disk aginst the flywheel. I am thinking the bolts holding the pressure plate to the flywheel have unscrewed.

Don't experiment anymore, pull it, something is seriously wrong and whatever it is could come completely loose and tear things up really bad at any moment.

Maybe a snapped input shaft?

[themadscientist]

He would have felt it snap and would have had to be doing some serious hammer drops from a stop with at least 300hp.

[articzap]

True.

Always loctite your pressure plate bolts. Simple thing to avoid these issues.

i thought about that and no funny noises whatsoever. I know what a bad throw out bearing sounds like and it goes into gear so that's not it. Yeah with the shifting while engine is running too.

Also i figured i would hear the pressure plate make somekind of noise as i press the clutch in and i still have that hard clutch feel when i press the clutch its not squishy at all.

[themadscientist]

Something is keepin the input shaft from spinning. Clutch, pressure plate ar input shaft is broke. Input shaft it pretty noticable when it snaps, Stripped clutch would make noise and smell burned. Point is you need to pull the gearbox and see what's up. Keep us posted.

[DRIFTBOI240]

will do, hopefully it isn't too serious but if it's the transmission i can swap my bellhousing into a ka or sr transmission right??? well from what i've heard. LOTS of 240's here in AZ so i know i can find another one cheap.

pilot bushing?

[articzap]

A pilot bushing would not cause any of those issues that he is having.

hrrmmm.... I would also be inclined to check the selector fork to see if snappage has occured...

Seems strange that you still have the pressure of the clutch, but even when its engaged (foot off the clutch) you can freely move the gearstick...

i had that once on my ka24e where the fork pivot ball snapped but that caused me no not go into any gear in this case i CAN go into any gear while car is on and without having to press the clutch....

UPDATE!!!

okay so i got the transmission off and that's fine. I also checked the pressure plate to be loose or anything and that tight and snug onto the flywheel. The culprit happened to be the clutch disc itself!!! snapped into two peices i would describe were but don't know the correct terms for the center and the disc outside lol sorry.... anywho here's the aftermath







spec clutch it was!.... the pressure plate is fine do you guys think i can get away with using another clutch disk itself like oem one maybe or try finding out how much Spec charges for the disc itself. I really dont know if i can trust another one as being this one was just installed about 4-5 months ago new so....yeah

[themadscientist]

I think Spec owes you a new clutch. There is no excuse for that sort of failure.

[meminto]

Glad to see you found the culprit..

FWIW, I wasnt talking about the clutch fork pivot, there is a gear selector fork inside the box itself that would allow the stick to freely roam ..

[MeanGreenS13]

dun dun dun... another spec bites the dust! ****ING JUNK!

yeah i realized that as soon as i hit post i reread it and noticed which one you meant lol

I'm sure they do cause that's not something i abbused lol i was barely getting the ca running up to par. Well i'll do a follow up to see what they say.... i'm not too convinced with their products as of now tho...

[themadscientist]

That speaker is attached about as well as the clutch hub was.

lol Dammit!! you weren't supposed to see my custom ziptie speaker mount

[themadscientist]

The ghetto tuning is strong with this one.

[Liquid_Neon]

sooooo spec clutches like to break?

thats pretty ****ty since spec seems to be the only ppl who make a ca18de fwd clutch. I can't remember if i had found anyone else.... CURSES!

That scares me but i still need a fwd clutch without haveing to custom fit 9 different things.

[dattodude]

Surely Daikin/Exedy make a CA18de FWD clutch.

Even a factory one would be better than the SPEC garbage.

I'm thinking of making these broken clutch photos my avatar.. that's so so so so wrong.

See, my problem is i can't seem to find a company that sells a clutch that will fit my ca18de flywheel and stand up to my turbocharged antics!

Spec seems to be the only ones, exedy doesnt list anything but oem replacements in the USDM.... dam ppl under rateing my car!!
