But this is probably the forum I should have placed this in:

Have a 1999 Chevy S-10 2wd manual. Clutch was working fine, and is a relatively new clutch (i.e. less than 10,000 miles easy). However, it will not now engage. Only thing that I know is that the driver may have downshifted from 3rd down to second, and did not fully disengaged the clutch all the way. Although I wouldn't think one downshift like that would break anything as far at the transmisson/clutch is concerned. I can see the slave cylinder pushing the throw-out bearing into the pressure plate. However, when you let up on the clutch, it does not engage to the flywheel (i.e. with engine running, you can shift through the gears without the clutch but obviously it does not move).

the truck was not used heavily, and possibly very little over the last year.
Any thoughts on why the friction plate will not engage? more importantly, is there any chance of resolving this issue with out dropping the tranny?

thanks in advance,

Does it make any noises (rattling, etc.) when you step on the clutch pedal? It sounds like maybe the hub broke out of the clutch disc.

No, no odd noises. And the throwout bearing is flexing the pressue plate springs, and they flex back when you ket off the clutch.

As far as the clutch plate center, that wouldnt prevent it from being moved back to the flywheel as i thought when the pressur plate springs in the center are not flexed by the throwout bearing it forces the plate back against the flywheel

If the slave cylinder is good, and the clutch and pressure plate are good, maybe your slave cylinder isn't bled properly?
Otherwise, it's most likely the pressure plate has weak springs.

I always replace the clutch, pressure plate, slave cylinder and throw-out bearing when I do the clutch.

So your thinking that the springs in the pressure plate are not pushing the clutch plate back against the flywheel? Is there anyway to check that without taking the tranny out? (i.e. push the clutch plate with a screwdriver or something else that could slide between the springs on the pressure plate to see if it can be moved manually). Basically trying to not have to tear out the transmission if at all possible.

If your slave cylinder is bled properly, and the clutch rod isn't bent, the only thing left is the pressure plate.
* That is IF you have a good clutch pack in it.
