Clutch question

Ok first off I just want to say NO.....I did NOT fry my clutch It holds just fine ALL the time ...now that THAT is out of the way.....


I have a 2.2 G5. Anyone else notice this? ----> When the clutch is ALL the way out, and you ease it to the floor in 1st gear, wind it out to around 6000 RPM, then you shift into 2nd gear the clutch seems to grab really close to the floor? And it seems to grab alot harder than normal?

2nd....after the above happens....you stop at a light, take off normal and it seems like the clutch grabs close to the floor and seems a bit "grabby"?

The car has done this since day one.....Is it just mine?...or everyone?

The gearing from 1st to 2nd is really steep. That would be the jerk you're feeling. Also a lot more power at 6K than 3K.

I don't think I am explaining it correctly. It is a bit difficult to describe.

Lets say you take off from a light, then you go WOT....When you get to 6000 RPM push in the clutch put it in neutral and stop.

Then take off in 1st gear....the clutch will feel different than normal. Everyone with a 2.2 try this and let me know if you clutch is the same as mine....and no I don't normally go WOT only to stop and take off normally, but it is the best way to explain the situation.
Know what I mean?

I just don't think the steep gearing from 1st to 2nd should affect the engagement point of the clutch or the "grabbiness" of it. Just somthing I noticed about the car...I dont really think it is a problem.

my ss/sc does what you are experiancing aswell. im still unable to explain why it does it, i beleive it may be something to do with the self adjusting pressure plate but was never able to get anyone to give me the answers i needed to come up with a conclusion.

Sharkey...it is difficult to describe too isnt it? Almost feels like a chatter after a WOT run in 1st gear. But the clutch never slips or does anything funny, and after driving a few miles it goes back to normal.

It is almost like the clutch works BETTER after a WOT run, but also chatters a bit. Keep in mind there is NO aggressive shifting involved, and in fact, the car would do it even if you DONT shift at the end of 1st gear...just go to neutral.

i experience this too in my 07 LSJ although i have never gotten any answers from here about it. it seems to happen right at 5000 Rpm It doesnt matter if you are WOT or not you can slowly bring it to that RPM in any gear usually 1st or 2nd. say You take first to 5000 when you shift to second and let out the clutch i can not feel the engagment point although it does engage, then when i shift to third the pedal is stiffer and the engagment point is at the floor. Also the pedal effort or stiffnes of the clutch pedal seems to randomly change, somtimes its softer than the night before. And if I drive for an extended time on the highway like 30-40 miles and the car is in 5th gear for the whole time the first time i push in the pedal to take it out of fifth when getting off the highway the pedal will be stiffer. Right now i have 35,000 on the car and it has been doing this since like 17,000. The clutch still grabs hard and necer slips, so I can only imagine it being the slave sylender or the self adjusting part. un fortunatley If you go into a dealer and say "every time I go past 5,000 RPm this happens" they probably going to say you abused it and not warranty anything, so unless there is a TSB i feel we are **** out of luck. any one who can help please chime in because for the last year i have read this forum and this is the first time i have heard of someone else having this issue

mine seems to do it after going above 6500rpm. when i go to grab 2nd the pedal is soft at the top and heavy at the bottom, when i let the clutch out it releases close to the floor, same with 3rd gear, and thats even if i let off early in 2nd. ive also had it get firm after a freeway drive.

we did discuss it in depth once. rpm wont affect the slave cylender or master cylender, so those can be rules out. the only logical thing i cant think of is the pressure plate due to its nature. it adjusts to take up for clutch wear. as a clutch disc wears the fingers on the pressure plate have to come out further for the clutch to grab, this is what causes the high pedal on a car with a worn clutch. a self adjusting clutch (SAC) will adjust so that as the clutch wears the fingers wont have to come out farther as the clutch wears, they will stay in the same spot when the pedal is out. i always wondered if the increased rpm from stage 2 was causing this as it really only does it after a higher than stock rpm shift. what could be happening is the fingers are moving in (like compensating for a worn disk) from the centrifical force, causing the pedal to be low to the floor and harder to push.

what i couldnt seem to get last time around is input from anyone who experianced this stock and went to a non SAC style clutch (some spec, or the exedy hyer single) on weather the problem went away. now another curve ball here is that iirc the 2.2/2.4 doesnt use an SAC style clutch, if this is true then my theory is out the window being a 2.2l has this same problem.

Interesting. Mine has done it since it was brand new, and I am a bit glad to see others have done the same thing for many thousands of miles with no issue. Thanks for the responses.
