When I'm in traffic, or any other start/stop situation, after a while the following occurs:

If I rev the engine to just over 1,000 RPM, and try to release the clutch lightly, it feels as if the clutch is slipping, and I start to feel not only the car bucking, but also the gas pedal. the entire car starts resonating and shaking, as well as making these metal shaking against metal and grinding noises. If I give it more gas, the problem intensifies. I have to push in the clutch, and start over. I have to rev the engine to about 2000 RPM for this not to occur. It sounds and feels very worrying. I was hoping someone might have an insight before I take it to the mechanic. My thoughts were that it might be a transmission mount, but I just don't know enough about the car to make a judgement.

Any help or insight would be appreciated.

My first thought reading you message was tranny or engine mount, but it's also possible that you have the original rubber centered clutch and it's time for a new one due to deterioration of the rubber center. The shaking and metal to metal sound could be the safety/limp mechanism coming into play.

Just my thoughts, definitely no expert.

JG,

This just start happening? Why didn't you mention something yesterday.

While a Carrera clutch will last at least 60,000 miles, like anything else, they can go sooner with some abuse. Sounds like you need a new clutch. Prior owner may have burned it.

Call DeMan tomorrow, I'm sure he can answer your question.

Rich -- Good call. I didn't want to turn saturday into "fix Jared's car day." It didn't seem appropriate to haul in my car and use the time to that effect. although I could have mentioned something, with that many porschephiles around.

Ah well, live and learn. I'll call Deman, and my own mechanic gets back from vacation on friday.

Thanks.

I'm just curious about the downside on this one -- what ballpark am I talking for a new clutch to be installed?

Thanks.

A new clutch in a G-50 car is about $1.8 - 2k but be prepared for other items (syncros, oil tubes, etc etc) that might best be delt with at the same time as the engine and trans needs to be dropped and its more cost effective to address anything that will require that all at the same time.

A good shop can help you decide what needs to be done and when.

good luck

JGordon,

Total parts & labor will run you about $2,000.

I was reading some posts on the pelican parts BBS, and they mentioned burning clutch. Well, When I'm parking (garage in manhattan, no other choice) I usually keep the revs about 1100 or 1200, and use the clutch to maneuver. Low speeds, forward and reverse. Whenever I get out of the car (after using reverse to back into the space), I notice burning clutch smell. Is that indicative of clutch about to go, or bad driving by me? I'm REALLY not happy about what this seems to be turning into, but anything you guys can offer as ways to track down the problem would be appreciated.

Finer points: this usually only occurs after a lot of start and stop traffic (which we have too much of in NYC). What's strange to me is that it only occurs in the 1100 to 15 or 1600 RPM range. When it occurs, I'll try to let up the clutch, and I'll start feeling what seems to be the clutch catching and releasing through the gas pedal. The entire car start shaking as if the problem starts a resonance throughout the car. I can't accelerate from there, more gas only intensifies the problem. However, if I depress the clutch pedal and rev the engine to 2 grand, I can release the clutch again, and there's a much smoother uptake.

Please tell me that there are other possibilities than blown clutch. I have put less than 4,000 miles on the car after acquiring it with only 43,000.

I'd put in the little "Guinness-drinking" smiley face, but I don't think I'll have enough money soon to drown my sorrows.

I had the same problem on my 88 Carrera. My clutch exhibited the type problem that you were talking about, but also a slightly different mode. When I was at a stop sign or sitting with car in neutral, when I depressed the clutch, it would not go into gear half the time. What was wrong was the rubber centered disk was deteriorating and crumbling and getting between the pressure plate and flywheel. My short term solution was to kill the engine, put the car in 2nd gear and then take off. This worked only if speed was not a factor, and it got me from point A to point B. If the clutch is the problem, go to the spring type disk or the problem may occur again. Mileage is not the only variable on the rubber center. Heat and time are the primary culprits.

JG,

It's not your driving, you need a new clutch.
