Clutch on its way out?

[finestjammy]

Hi all

I've got a 2009 987.2 Cayman S, done 46,000 miles, 6,000 of those in my ownership. In gear there is not a hint of slip, any gear, any revs, foot hard down and just linear acceleration in line with the revs rising. I tried the set off in 5th test and the car duly stalls. When changing gear under hard acceleration though (1st to 2nd is the most noticeable) there appears to be a slip of sorts. The revs don't raise dramatically with no forward momentum but they seem to retard slightly. Hard to explain, as you've probably realised, and I haven't noticed the traction light coming on at the same time. It feels a little like a limited slip diff.

Anyone had the same experience? Imminent doom?!!

Thanks.

James.

Might have answered my own question. I believe there is a clutch delay switch and/or software to save hammmering the drive train on 'enthusiastic' up shifts. BMW had an actual valve attached to the slave but I think it's built into the software on the Porsche. I'll keep an eye on it.

It is very odd, you'd expect a 'sports car' to have snap back onto the power after a change. I'll take a look at that little mod

Be sure you have the brake/clutch fluid flushed/bled every 2 years. My experience with my 2002 Boxster is after 2+ years (close to 2.5 years) the clutch action can be affected and this in turn affects shifting from past its change by date brake/clutch fluid. (The two systems share fluid.)

A brake/clutch fluid flush/bleed "cured" the grabby impossible to enage smoothly clutch -- which had heretofore had not beeen grabby and easy to engage smoothl. It also "cured" the crunchy shifting that had me at first believing I had lost the clutch/shift lever timing then when focusing on this and having no better success believing the transmission was going bad.
