Clunk Clunk Cluck silence - No Gears | WHAT BROKE?

Need a little help here Gentlemen...

New to 986forum too.

1999 Boxster, 53,000 miles, White.

The last few days I've felt a power loss / lag when releasing the clutch and the amount of pedal with torque seemed gradually less.

Yesterday morning, I was driving in 1st and 2nd leaving a very long parking lot and I came to a stop sign and gently let off in 1st and a very loud CLANK CLANK CLANK with a rotatory repetition began. Something big broke.

I made it 50 feet and it seems as there was no second gear. Being 300 yards from home, I hoped to limp her home in 1st gear. If I was very gentle with just a few RPMS there was no VERY LOUD CLANKING. Just a small bit of travel in the clutch petal where I still had power to the wheels.

I made it about 100 feet and then it stopped and 1st gear was gone. I checked second gear and I'm fairly sure that the clutch has no actuation. And I rolled her home.

WHAT Broke?

I'm a fair mechanic, I have all the tools and I love this car. I live in Palm Beach so the weather is good for the repairs and there is an endless line of blonde girls that want a "ride" - Please advise.

Thank you
Jeff

CV Joint exploded. It happened to me after I had the car a week with 90K on it.

It's either a CV joint, driveshaft, or clutch. It's possible that the transmission broke, but not likely.

The CV joint came to mind first but if the clutch pedal feels iffy could be a broken fork (throw out bearing) as well.

The CV joint is very easy to check (visually) but the fork it's a bit more complicated as you will have to remove the gearbox..

Hmm... A bit more.

The car has been babied. Literally wiped with diapers.

I've been good to the car less a few times I over revved past the red line.

On Tuesday I raced an R8 off the line (and have only done this type of driving a handful of times) and I could feel the shifting was not perfect and there was some slop. Where i revved past the red line as the clutch pedal was not as quick as it needed to be.

The clutch pedal has been tight although actuation seems as it was only at the end of the pedal travel. To the point it's easy to cough out the car in first gear and has happened once a week for the last few months.

The clanking was rotary. Very very loud metal banging on a 1 to 1.5 second interval with about 3 very loud clanks.

I would adjust to quiet the car attempting to limp her home. As first gear was making a ruckus with the clanking I tried second gear and I'm fairly sure I had nothing. When I would rev over 1500rpm ish the clanking started.

About 12 clanks total and then silence. First gear was gone and there is no mechanical connection today.

I have not looked at or under as it is... awkward, raining today and you guys (and gals) know where I should start...

These cars have a duel-mass flywheel your issue may be with it.
I always go with simplest things first and work my way up step by step.
So check the things mentioned by the other posters first.
Like things that could cause the clanging noise.
CV joint,axles and so on.

Sure sounds like clutch- time to me.
Check the easy stuff first, but I think you'll be dropping that gearbox. I bet when you do, little pieces of clutch rain out on ya.

This is what it sounded like when my axle was snapped in two pieces after being hit on the race track. You'll hear the grinding sound at 1:15 into the video (just shortly after my cussing at the other driver for hitting me! .

Take a look under the rear end and grab each drive shaft and wiggle to see if there is any slop. If its a drive shaft, there will be LOTS of slop.

with a broken CV you wouldn't have any drive. so maybe it partially broke and then expired upon stopping. Could potentially be a shift fork or clutch disk also.

Gotta take a look and start crossing out potential culprits

Thank you Everybody. I'll start the investigation on Tuesday the 17th! I'm headed out of town for a few days (to see more blonde girls... with a RS2).

I'm really hoping it's something like the axle. It's big and heavy metal clank center under the car. I suspect it may be the flywheel or that size as the amount of vehicle travel before the sound was repeated was radial and geared to be about 5 plus inches and it rotating and hitting something that was noting going to to move. Hardened steel over 1/2 inch thick Clanking/Banging.

The car is 20 years old and I've had a chance to prove her a bit around Palm Beach and it's done great.

I'll update next week! Thank you again. Way cool.

You know if you use your phone the pics should be a size your used to. +/- 3 inches?

Just kidding Starter. As a new guy, am I allowed to make jokes?

If it was a drive shaft or CV joint, wouldn't he still be able to shift gears with the clutch feeling normal, just no power to the wheels. Sounds like clutch/flywheel/throw out bearing issue.

I would greatly appreciate a head up.

What is this?
Where can I get the parts the cheapest?
A video link to the repair.

I have the tools and I need to park this in front of a serious yacht in like 7 days.

Gentlemen, please advise. Thank you

That's the CV Joint where it attaches to the trans

https://www.youtube.com/watch?v=5V1uAoFl0qw <-- not a really in depth video but you should be able to find something similar.

What you are looking at is the inner joint cover.
