Soooooooo how's the car doing? Put a bullet through the crankcase or have a good porsche tech look at the history and get a listen?

Any progress on this one??

Just found out that my transmission makes sometimes sound like this. Not as loud and not all the time.

Just got 3k km after the engine rebuild, so now the transmission need's rebuild... Or maybe change to M3.... :P

Oh no... well at least the engine is running strong.

Yep.
I can't hear the noise if I stand next to the car, only when I was under it.
In the grease pit...

Hi apanossi,

Did you make any progress regarding the clutch noise in your 996?

I would very appreciate if you let us know the solution that worked for you, in case you already find it.

Thanks a lot,

Luis.

3 months and no real results? I'd dump your workers and find a dealership or race team that's found all the odd screw ups already and knows the sounds and can spot the problem from reviewing your symptoms that go along with all the repairs tried again and again.

One trick you could try but not want to is not push the coutch in and try putting the car in gear while its running to get close to actual gear engagement. You don't want to grind gears but get the syncro's working and add some change to the shafts to see if the noise stops. If the syncro's don't allow getting messed then I'd try getting them started with the cluch in slightly or all the way before gear engagement and see if the nosie changes and how it changes. I'd try different gears and reverse. I'm not sure if there are two seperate shafts for odd and even gears or what in there but you do have to find the problem. Sorry to hear its been a long haul of failures. Maybe get fond of modern rock and roll that sounds like that racket?

Sorry guys. My car was rear ended at the end of December and it's been in the body shop getting work done since. Total of $18k damage. Insurance company wouldn't salvage it. Anyway, mechanical is finally going back in the car. I was going to explore the possibility of the trans input shaft. I'm not sure if i'll end up with an answer on this one. I'm not sure I want to throw any more money at it. But if there's clear cut evidence this last time, then I will definitely post the solution.

Wow thats bad on the rear getting thrashed. I hope you are doing OK. I think most insurance companies allow disputing the way claims are handled. I don't think anybody but Porsche is the right people to handle repairing major damage like yours. That alone would probably throw the cost of repair over what the insurance considers totalled.

Hi apanossi,

Sorry your car was damaged; I hope you will enjoy it again after they fix it.

Thanks for sharing the solution if you finally get it,

Luis

Ok guys. At wits end, I decided to get a new transmission to solve this problem. Well, I'm happy to say that the problem has been solved...so far. The old tranny is on the way back to Porsche for diagnosis. This has and continues to be a mystery to me, but it is now clear that the problem seems to have been with the transmission itself. I'm not sure what would cause these symptoms mechanically within the transmission, but I'm back to loving my car again. I know it's a bit anti-climactic, but I thought I would post what seems to be the solution to this issue thus far. Hopefully, I will get an answer at some point from Porsche on this and share it with everyone.

I hope it was your transmission. I had a rebuilt one put in because the old one was 'noisy'.... nothing like as noisy as yours and not even a pulsating noise as yours was. Mine was just loud inside the car. With the top down (I have the cab) it was hardly noticable. Only with the top up and windows closed was it loud. Since the upgrade. The car is really quiet. Hope yours is a success.

Really late to this thread, but if you still have a recording of the sound any chance you could repost it?
