Default Clutch Adjustment?

I was out this past weekend. Car only just turned 19k and I've gotten on it a couple of times, but this weekend when I did I didn't let off it fast enough and felt it slip a little and could smell it burning. Didn't quite feel right after that. Feels a little "thin".

Can a stock clutch be adjusted? If not, what kind of job to swap out? Any Faq' docs with a blow-by-blow?

Thanks...

No, no adjustment of the clutch hydraulics, or clutch for that matter.

Changing clutch...not that bad.

1) Get car up in the air, I recommend jackstands at the normal jacking points.
2) Remove X-brace if equipped
3) Remove exhaust center section
4) Remove console and shifter **** to get to the top of shifter area
5) Remove 4 acorn nuts holding lower shift boot to transmission
6) Remove lower shift boot, place shifter in 3rd
6.5) Remove distributor cap on L98s. When you lower the transmission to remove it, the motor will tilt backwards and may crunch the distributor cap against the firewall. Be safe, if L98, remove it.
7) Remove driveshaft
8) Remove C-Beam (torque arm)
9) Remove slave cylinder, do not remove hydraulic hose
10) Remove transmission
10.5) Remove Bellhousing - may need to loosen clutch fork ball stud to get clutch fork separated from throwout bearing
11) Replace necessary clutch components
12) Replace all parts
13) If anything left over - uh-oh

Not bad?!?!?!? It has taken me over a year, then of course I have been going slowly and cleaning up the car. But otherwise it sounds like your clutch disk is slipping. I let mine slip for almost a year until one day I accelerated and ripped the disk to shred, my ignorance. My problem was from contaminates and oil. If you can smell something burning and this problem continues change it ASAP.
Good luck

Dumb additional question - what about the bellhousing?

Thanks for the bullets. Doesn't sound that bad. Biggest PITA sounds like the console to me.

Bellhousing bolts - not too bad. Add another step in the above...

6.5) Remove distributor cap on L98s. When you lower the transmission to remove it, the motor will tilt backwards and may crunch the distributor cap against the firewall. Be safe, if L98, remove it.

Now, with the motor tilted, and the transmission removed, the bolts on the bellhousing can be gotten to pretty easy. I have a set of wobble extensions and they help out tremendously. The hardest bolt for me to get to was the driver side, middle bolt. The one marked "y" below, when looking at the heads of the bolts. (dots added for spacing purposes...)

y.....................x
