I believe this also included labor for a TSP on the clutch.

Regardless, I do appreciate the absolute insistence of accuracy whenever posting on this forum.

I use castrol srf, it's as good as it gets. I guess I just have to deal with this until I pony up to take the trans out

I also only use SRF. Liquid gold and worth every penny.

Yes but I swear I still get fade with them on my brakes

One thing I read with the higher temp fluids is that they suck up moisture from the environment much faster than the lower temp stuff. When was the last time you replaced the fluid, not that cali is a very wet/humid region?

My clutch was slipping at 35k. Bought it used with 22k. I'm guessing the previous owner didn't know how to drive stick, or beat the balls off the clutch. Called in a favor at Nissan and had it covered under warranty.

UPDATE.....
3+ years, and 30k+ miles.... Stock clutch still going strong. Hmmm. maybe the dealer was trying to get me for $1800????

This isn't a fluid issue. I had this happen with RBF600 on the street and strip. Definitely CSC related. It's just not putting enough pressure on high rpm shifts. It feels similar to a weak clutch, but it only happens when shifting at high rpm. I replaced everything instead of guessing what was what. I have the SpecialtyZ clutch and flywheel now and it's been outstanding. No more slipping.

THanks

More than likely it isn't your clutch, but your csc going out. I had the same issues as you're describing and when i replaced my clutch come to find out the flywheel and clutch are in really good shape.

Also try flushing your clutch line and replacing it with brand new fluid, then go recheck it in and month or two. If it dirty again then its probably your csc going bad or master.

bad clutch fluid / CSC shouldn't cause clutch to slip because since pressureplate is mechanically back to it's original position which is engaged to the flywheel regardless when pedal is not pressed. fluid/csc should only contribute to clutch disengaging from flywheel so in the case of bad fluid/csc/mc, you would only have problem disengaging. my guess is that pressure plate is bad, or clutch is unfortunately burnt. i've had bad pressure plate which the teeth ended breaking off, and had the same symptom of slipping before eventual failure.
