v6 t5 vs commodore 96 model

[rossvs96]

it is shuddering from take off and through all the gears can someone please help with this. it has a heavy duty clutch in it. i have only just brought the car

Sounds like a warped Flywheel, just like mine, it gets worse as the cars warmed/driven longer?

Could also be the car sturggling underload but it shouldnt do this through a gear change unless you change far to early.

[rossvs96]

yeah it does and it vibrates while idling and sitting still.

[W8INL9]

yea i agree with Tom_1569 it sounds like a warped flywheel or something similar ??

If it's doing this, I check the engine mounts, especially the rear one. If they get oil soaked they go soft like jelly and allow the powertrain to flop about making smooth clutch engagement impossible.

[rossvs96]

engine mounts fine they are still hard. i have just had a look and the clutch cable is adjusted right out so im guessing that the clutch is buggered but will it cause this problem?

[hako]

Engine mounts may be hard but they still can be sheared. If it was me, I'd eliminate the cheaper options before pulling the clutch out. Is the manual a retrofit? - I thought all VS had Getrag boxes with the dual mass flywheel.

[rossvs96]

the previous owner had converted it to manual.

[hako]

The cable being fully adjusted should not cause judder. If it's happening on all gears as you say, and at idle it vibrates, I'd still suspect bad engine mounts. A worn clutch will slip not judder. Another possibility is oil on the clutch - remove the lower cover and see if there is oil on the pressure plate.

[delcowizzid]

if it vibrates at idle as well it could have a flywheel off a vp or vr on it and they are balanced wrong for ecotec

I just thought i'd point out that the VS series 1 got the T5 box and series 2 onwards got the getrag...

hope this helps

Hmm, could be very badly warped, I would look for something else before Flywheel if it vibrates at idle
My Flywheel is rooted, it vibrates on take off, and kinda vibrates on changing gears, kind of a grip, slip grip thing as it cant grab properly.
At idle the only thing I can is the Throw out bearing grinding away as its ####ed from the flywheel.

The Excedy flywheel is around $750 (T-5 one) or you can get a cheaper version off Not_an_abba_fan for around $350ish I think. Replace your clutch at the same time so both surfaces are flat.
Do not machine, I tryed this, one hard trip of Mt Hotham and she was warped worse.

[rossvs96]

It is a series 2 and the previous owner has put a t5 in it.

[jujibelly]

Could be misaligned clutch.

IF it vibrates all the time i will put money on an incorrectly balanced flywheel (seeing as it's converted). I had a wrecker convert my VS with a brand new flywheel, and it vibrated everywhere in the revs. I pulled the 'box out got the pressureplate zeroed and the fly balanced now its all good.

A missaligned clutch, would cause the gearbox not to spline in with the clutch

as for the vibration i had the same issue in my old vs..

i never got around to fixing it, got a new box n clutch and machining of the flywheel cause it was shuddering on takeoff ..

I thought it was some kind of balance issue to do with the balance shaft or balancer it self.. tho i never really knew what it was.
Now i own a vs series 2 with a T5 gearbox in it and apart from my button clutch destroying my diff it drives real smoothly

[Super_Low 91]

Thanks for the info guys, reading through this has helped me work out the issue i have with my car, looks like its time for a new fly wheel an clutch,
Mine shudders on take off only.

[vscom88]

just get ur flywheel machined mate, flywheels are not cheap, especialy if ur running a dual mass like i am .. my flywheel cost me 1000 but its not the standard 1..

super stop brake n clutch (if ur in vic) can test ur flywheel for balance issue and will machine it, as for the clutch, go a heavy duty 1 .. if you can get trade price they a fairly cheap.. i paid 460 for my on/off ceramic plated button clutch
