Clutch question...
 

I know my trans has a hydraulic slave cylinder...thats it. i dont know much else. But when I have the clutch pedal down the engine and trans are smooth, no noises. But when i release the pedal (with the shifter in neutral) it sounds almost like a rod knock and it all vibrates.

I'm thinking its a bearing of some sort...a throw out bearing or release bearing...anyone got any idea or could it be either of those?

does it go away at all? what about when ur in gear?

when the clutch is mated to the flywheel it makes noise. when i disengage it, the noise goes away.

so there is no noise when its under load? i had a similar thing but mine was only when the engine was under load, like i was in too high a gear and would try to accelerate, or right when i started from a dead stop it would vibrate and then stop. mine did it and its a very common hting on LT1s. i wouldnt worry about it if i was you. everyone knows what it is but has no reasoningto why it does that.

youre a dork...any manual tranny will cause the car to vibrate if in a high gear trying to accelerate...

could be the flywheel is slightly warped.Really anything on the surface of the clutch even could cause that (just a piece of junk that somehow got in there)

not all of them ... his was the 1st i was in that did that... it was a kinda weird sounds... almost like some metal rattling agiast anmdother peice of metal

oh...well mine does that when you smash the gas in 6th going like 40 mph...

well before u go out buyin a throwout bearing id just check to see if anything metal from the tranny is touching something. might have that kinda effect but i honestly dont really know man.

well a throw out bearing is only 20 bucks or so...i can do the labor myself i just dont have time...

yea you can do the labor yourself but you dont have time. EXACTLY. have fun getting that crap outa there. its a lot of work

and like i said its common on LT1s. i have an LT1, so do you. same situation...

and while your in there check everything out real good

well someone help me out a bit...the clutch and pressure plate are bolted to the flywheel and the throwout bearing is on the input shaft inside the bellhousing of the tranny right?

right
