You are looking at a picture taken from a mirror held in the starter opening on a 5 spd transmission. The Red Arrow is pointing at the clutch material remaining and you can just make out about 1 mm or so of the 'slot' that is on the surface. Am I correct in taking that to mean there is some life left? This is pretty much a stock 2.8 and I don't do clutch dumps or hammer the tranny in any way. What's your opinion, totally ballpark, can I get another few thousand miles out of this? When the car is on the road I put less than a thousand miles per year.
I've never observed any of these signs of slippage. Since I only drive this maybe a 1,000 miles/year if that seems like I'm should be OK for a while. My plan is to leave the short-block alone until I can switch it out for a 3.4, at which point I'd do the clutch as well. Appreciate all the feedback.
We nursed a slightly slipping clutch on a V-6 Getrag combo for a couple years of summer driving. A clutch that slips a little probably will not fail over night on you, but as you notice the slipping starts in the lower gears you time is running short.
You need to see if you can get a better look at the disc on the flywheel side. If you have the same amount of space in the material "gaps" on the flywheel side then you are OK. If the gaps are gone then you are near the rivets. Clutch disc have much less material thickness then brakes. Only about 3/32 on each side new over rivets.
If you feel brave you can do a 1st to 2nd power-shift and watch the tach. If it doesn't drop before going higher you definitely have a slipping clutch. Also don't overlook a weak pressure plate.

Can you (or someone) please post a side view of a 'good' clutch? I can't visualize what you mean here.
Personally I would not even worry about it. GM OEM clutches last a long time. If it seems to work fine it is a good clutch. 8 years ago I installed my built 2.2 ecotec so I ordered in a new clutch. When I got it in I sent it back because it looked the same as the old one. It is a lot of work to take every thing apart just to look at it. Better just to wait for it to start to go and then replace it. It isnt life or death like losing your brakes. The car will just stop moving, then tow it home. I drive old cars, I am a CAA member for that reason.
