Clutch slipping? WTF?

[greenmachine97]

Ok, i just replaced my clutch(disk & PP), TOB, resurfaced the flywheel, well actually i had Gabor do all the work because it was his parts, but i havent rebuilt my master and slave cylinders yet. i am doing it this weekend. but here is my problem. if i accelerate slowly in first, and smoothly shift into 2nd, then punch it in 2nd, i can here the turbo whistling like a SOB, and the car pulls alright. but not as hard as it should. so i let of the gas for a split second, and then floor it, still in 2nd, then the tires chirp and it pulls like a raped ape. the same thing happens in third, and fourth. i cant tell if it happens in 1st because if i boost hardly at all, i lose traction. but in any of the other gears, i have to let off the gas and then hit it again in order for it to grab and pull as hard as it should. after doing this, i can kinda catch the smell of something burning, possibly clutch. will this problem be fixed after i rebuild my master and slave cylinders? or should i be prepared for other larger more expensive problems ? thanks for the space.

They may have screwed up your Flywheel - IMO a bad Clutch Master and/or Slave Cylinder wouldn't cause Clutch Slippage - take it back to the Shop quickly & my son called me today - Clutch is slipping in the '91 so I guess I get to have some fun...

so that does sound like my clutch is slipping, it is really hard to tell. i am going back to Gabor's place within the next week to do my master/slave cylinder. so i guess we will find out, does anyone else have any ideas?

I have about 60k on my gsx and I don't think that the clutch should be going already. However, I do know for a fact that my slave cylinder is leaking.

When I accelerate from a low RPM, the turbo spools, but I feel like I am in a n/t. If I let of the gas and then punch it again, the car will haul ass. Could this maybe be some kind of funny boost leak? Why jwould letting off the gas and the re-applying the gas mak any difference?? Lemme know what you find out. Thanks!!

good, somone besides me is having this problem. anyway, i also know for a fact that my master cylinder is leaking. and like i said, i am replacing them this weekend. but i need to mentally prepare myself if this sounds like a bigger problem.

 

[noob-e]

I hope it's not. How hard is it to replace the master and slave? I am pretty quick to learn and I have all of the shop manuals and stuff...... Is it a weekend project, or more than that?

60K miles on an AWD Clutch is probably about average lifespan the way we drive - You can change all the Slave Cylinders & Clutch Master Cylinders you want - they are NOT gonna stop a Clutch from slipping.

 

[noob-e]

I have had the clutch go out on me before and it does not feel anything like what is happening now. Correct me if I am wrong......when a clutch is going out and you accelerate, the engine's rpm's will increase rather quickly but the clutch isn't grabbing, therefore it can't keep up with the engine and you don't hardly accelerate at all when you you are flooring the gas.

In this case, it does not feel like it is slipping, it just feels like I am driving a gs, not a gsx. It accelerates as if the turbo is not spinning. If I floor it, the car just accelerates slowly.

does that make sense?

i think u are descibing the problem i am having now. i am pretty sure my slave is going, because the clutch doesnt keep much pressure on long highway drives. more reccently i have noticed if i put it into 4th at 40 mph, and mash the gas, the turbo spools to 14psi and the car goes no where. the rpms are flying, and the clutch is smokin. im also approaching the 60 mark soon. im at 57,300. slipping clutch is no fun. i cant believe they go at 60k. im not even hard on it. time to get an act2100.

There's no oil/fluid leaking in that area? Something like a rear main seal would cause similar problems. Look in the bellhousing and make sure.

ok guys, i rebuild my master and slave cylinders with OEM parts from mitsubishi, along with installing a stainless steel clutch line, and removed the clutch pressure restrictor. All is well, and i highly reccomend those above items. it feels great!

My car seems to have the same problem.. I get a lot of intake/spooling noise but very little movement. Releasing and reflooring fixes it. One interesting thing, though, is that I've gone through two slave cylinders in past half a year or so. My current one is very new, installed right, and definitely clear of air in the lines. Does this mean I might need a new master cylinder as well? What else would cause that type of slippage/delay?

Master and clutch restrictor. Just rebuild the master, slave, and go to www.dsmparts.com and order a stainless steel clutch line. it will replace your restrictor, and you shall have no more problems!

It replaces the accumulator, not the restrictor. The restrictor lives under the banjo bolt on the slave. While putting on the ss line, you can also remove the restrictor.

RRE also has the ss line.
