Ok so i last changed my clutch about a year, year and a half ago. Almost right away, the clutch started slipping, sometimes it would be okay though. Fast forward to a few weeks ago, and after teh car sitting for most of the winter....i fire it up in the driveway..let it run at idle for about 20 minutes to get up to temperature, i get in it to drive it around for a little, and the clutch is slipping like a motherfucker. I cant get the car to move barely, after a few stop signs the car almost wont fucking move from a standstill, just rev and slip with clutch pedal out all the way. But if i let teh car sit for an hour and get back in, itll grab for a little, til it heats up, then itll do the slipping thing again. So, I was positive it was new clutch time, today, i finally pull the trans and take a gander at the clutch. Low and behold, its in almost perfect shape, hardly any wear whatsoever i compared it side by side to the new one and its almost got the same amount of material left. Pressure plate appears to be fine also. Flywheel surface also checked out fine as far as I can tell. No scratches or apparent warping. Anybody got suggestions? Master and Slave cylinders were also replaced brand new a few months back. I suck at this shit, someone give me some guidance please.

Adjust the clutch pedal?

1. Check Clutch pedal adjustment for free play. 2. If your clutch is in good shape, then check your pressure plate. The springs could be shot forcing it to slip by not pushing the clutch plate to the flywheel. 3. Even though you say your clutch plate is good, do visual inspection, if there is any contaminaiton on it-you should replace it. 4. Check your flywheel for contamination as well.
you need to adjust that c,utch pedal. give it some free play. the more you have the quicker the clutch will grab.i have about an inch. when i picked up my car it felt like the clutch was shot. i grabbed a 12mm and a 14mm iirc and adjusted the free play bc there was none. all the sudden i get in the car and its driving like bran new. also by friend had a shot do his 300zx clutch and when we picked it up he got in and it was like they didnt do the clutch job at all the car wouldnt move. luckily i had my tools, since it was after hours at the shop, and i adjusted it and presto it was brand new in minutes. so play with the adjustement. all you have to do is get a couple of wrenches and a pair of vise grips. then break free the lock nut and play with the shaft turning it one way or the other until the pedal can move about an inch or so with out feeling firm. like it will just move freely. then get in the seat and start the car. put it in gear and slowly let the clutch out. see where it grabs. if you like it shut the car down and tighten the lock nut. if it catches too high give it more free play if it catches too low get rid of some free play. hope this helps you out. :hsdance:

same happened to me, but it was kinda all of a sudden. i just pulled over and adjusted the clutch pedal and took off. its pretty simple to do, you just have to be able to cram yourself underneat the dashboard. good luck, hopefully eveyrthing works out for you.
