FEW questions, ANY help is appreciated. figured it would be better to start a thread to get up to date info on my specific build/situation.

cliffnotes: will i have everything i need to do a good clutch swap or do you recommend other/different parts. i plan to tvs my car one day + other mods as well. daily driver, driven hard. occasional 1/4 mile.

ok '06 stage 2 lsj w/ 45000 miles on it. gonna be swapping my clutch this weekend. i have the gm build book to help me and a buddy who's done 10 clutches do it.

so far, i have zzp stage 1 axles, and the revised shifter bracket for the lsj. i know, not rly clutch related but swapping those out at the same time nonethless

main question: most of the time, if i'm at idle and i press in the clutch, the car stutters, the rpms drop momentarily. what could be causing this? very annoying to deal with when i'm in stop and go traffic, the car HAS died a few times because of it.

so! heres the other stuff i'm planning to get, few questions along the way

lsj clutch upgrade kit: seems like my best option for the money and driveability :edit! comes with the upgraded throwout bearing, apparently.
Ecotec LSJ Clutch Upgrade Kit 19212712

new flywheel

new clutch pipe
Cobalt Clutch Pipe 24422067

can i reuse my stock flywheel or do i need a new one/upgraded one?

and, since it was suggested, a clutch pilot tool
Ecotec Clutch Pilot Tool 14534

upgraded throw out bearing! recommended or no?
GM ACDelco - Upgraded Throwout Bearing for LSJ #GM-24242805

redline mt-90 manual trans fluid (my trans feels really notchy, i'm sure a twm kit will further solve that problem one day. anyone got a better fluid suggestion?)


thanks for any help/sugestions at all! i will be updating this thread as i go along and revise how i'm doing this, and as my q's get answered. thanks all!

 

u will want to resurface ur flywheel

I am surprised they are doing their power limit by HP and not TQ

 

^^yea me too but it seems most ppl that run gmpp clutch are having no issues with pretty big power/torque figures so whatevs

and bump! need more info guys

 

Sorry I can't answer your question but I agree with the parts list you got.

 

I just got ZZP stage 3 in my car, went with a new flywheel so there wasn't any down time with re-surfacing. Stage 3 is overkill probably for what I'll be doing with the car. But I also did the new revised (LNF) throwout bearing, new clutch pipe and revised shifter bracket. Also did ZZP axles while I was in there.

BE CAREFUL. My brand new oem throw out bearing is leaking. I've heard of that happening to others too, and now the whole thing has to come back apart to replace it.

 

^^ ty for the info and warning. sounds like a pretty similar setup, i was considering the zzp stg2-3 clutch i'm not sure though..

any ideas to why the upgraded throwout leaks?

 

bump anyone know why my car bogs when i hit the clutch in neutral? anyone else got that issue?

 

GMPP clutch is awesome, upgraded TOB is a must, at least resurface the flywheel.

The one thing I would NOT use is the Redline fluid. Go with the GM LNF Trans fluid.

 

Don't know why the throw-out bearing went. It's speculation until it gets disassembled, but I'm 99% sure that's where the leak is coming from.

I went with Redline fluid in the trans and don't notice a problem with it. Alleycat, did you have a bad experience with it?

 

either that or i have a connection with amsoil maybe i could get their trans fluid

and yea i'm gonna just buy a new flywheel too

 

Welp, just bought all the above stuff. wish me luck!

still have q's though

 

i heard its a pain in the ass to do it..

 

I know... i'm scare

 

well if you become a pro at it, come to miami and change mine for free

 

gmpp upgrade kit already comes with LNF throw out bearing

 

thats great to know i noticed that, thanks for the input man!

 

the clutch shares the same res as your brakes. it doesnt have a separate one. as far as your other questions idk as i havent done one yet

 

Is this buddy Sean? He's done like 6 clutches on Cobalts alone, so I hope so...

 

saving for later. good questions and good approach

 

Newp. Went back and forth and got feedback on many different people who know their ****. Honestly, the GM LNF fluid can't be beat so I didn't see a reason to go with anything else.

 

haha nope my buddy whos gonna help me for free seans my back up plan though

great to know, i wonder if this is the problem then: i need to fully bleed my brakes, could a not fully bled brake system have anything to do with idle surge when i press in the clutch from idle?

thanks for viewing

lnf uses dif fluid than lsj?

 

No prob. and yes the LNF uses a different much better fluid than the LSJ. Its what im running in my car along with the GMPP clutch

 

I have the Redline MT-90 fluid in mine... shifts nice and smooth now. Didn't know about the LNF fluid.

 

This is some awesome info, I am going to be following suit on this one. My throwout bearing is shot and i just got the car!

 

so how do you know if the throwout bearing is shot? gosh i feel dumb but honestly i have no prior experience with clutches/transmission work so this is all a huge grey area for me..
