slipping clutch??

[cam98aro]

i just purchased a clutch, but i seem to be doubting mine is actually bad

i got my car with 90k miles on it, and put 40k on.. so it may either have 130k miles on the stock clutch, or it may be a different clutch i have no idea

anyways, sometimes.. especially on hills where i have to give it a lot of gas and slip the clutch a little bit, after i let the clutch out, i still feel my rpms dropping while driving the car

lets say i am reving it up to 2000 rpm on a hill, i will begin to let the clutch out and they will drop normally.. lets say to 1800 rpm, then after it is fully out it will go down to like 1500

i have no idea about the rpms but i can feel it while driving (i mean, i havent looked at my tach while pulling out since i first started driving a manual)

this basically feels like when you give too much gas while letting the clutch out, but the rpms still drop AFTER i let the clutch out

also sometimes, usually when i first start driving my car, upon letting the clutch out the car will vibrate like it wants to stall.. i assume this is clutch chatter?

i had a ton of hydraulic problems last winter but they went away

also my friend drove my car and says it doesnt really feel grabby.. but my clutch is not slipping

so is it good to replace it?

Re: slipping clutch??

could be a warped flywheel which is replace all clutch components but easy test to see if it slips put it in fifth doing like fifteen mph and just floor it if your clutch slips it is going to do it now since the engine is making the same power as anyother time but the gear multiplication is holding it back

Re: slipping clutch??

this doesn't sound like a slipping clutch, if it was slipping the RPM's would go UP not down. Our hydraulic systems have a restrictor in the line which helps regulate how fast the clutch grabs. Dirty sludgy fluid could increase the viscosity which would slow engagement.
When your RPM's go up and your speed stays the same, that's when you have a slipping clutch.
The bucking thing is caused by not giving it enough gas and it starting to stall, then the power kicks in and the car surges. Upon surging it cause driveline components to bind then everything gets out of whack and it does it again and again. You think it's bad in a 225ft lb v6 try doing it in an 18wheeler with some big azz diesel engine. :)

When it starts bucking like that just let off the gas and let the momentum take the car or downshift.

I would recommend flushing out the fluid at least if you are up to it. That really seems to help solve alot of problems in these cars.

Re: slipping clutch??

its not bucking, it is vibrating

and it happens at all rpms when i let the clutch out

anyways, i just got a new clutch/slave cylinder today, and holy crap, the clutch disc was very thin.. i was expecting it to be a thicker material like a brake pad

edit* im confused

is the slave cylinder on the input shaft? and the TO bearing is on the slave cylinder?

Re: slipping clutch??

slave cylinder is on the input shaft with the TO bearing, you want to change this with your clutch because both require removal of the trans and changing just the clutch and pressure plate will likely cause the slave to fail soon because you are trying to release a new stiff pressure plate with an old worn slave.

The master cylinder is attached to the firewall and goes to the clutch petal

Typically when you buy a slave it comes with the TO bearing.

If you have it apart you might want to check out http://www.installuniversity.com/ and do the clutch line restrictor mod.

thanks, i dont really want to drill anything in my lines

i already have everything i need to do my clutch, the TO bearing is on the slave

i just need to do it, and get my flywheel cut down.. hopefully its not warped or anything

Re: slipping clutch??

Yeah I second what black98v6 said if it was slipping the RPM'S would go up not down. I think there might be something wrong with your hydraulic system or the fluid because there is obviously something or some type of restriction thats keeping your flywheel from maintaining its RPMs.

well my theory was that it isnt slipping after i have already released the clutch and just while i am releasing it.. more than usual

you let the clutch slip every time you use it,and yet when you are letting the clutch out your rpms drop, they do not go up

but since i realize now that the slave an TO bearing are one.. it looks like when that happened to me i was getting a slow engagement of the clutch.. like stated in this thread.. but it also means it was slipping

Re: slipping clutch??

hey, how do i know which side of the clutch is engine and pressure plate side? it doesnt say anything on the disc itself
