My trans damper(477.521.603) started throwing chunks of rubber out the bottom of the torque tube. Does anybody have a source for these? Everywhere I look they are NLA. The 944 has a different part number, so I would imagine it wouldn't work? With it being this time of the year, just buying the 931 and the N/A being my daily driver, this is really killing me.

Any ideas? is there a way around it? install a clutch?

So, it's an automatic transmission...?

Good luck with the clutch install!

Yes, a clutch, if the damper breaks the torque tube will no longer turn, car goes no where. Can't find a damper, if a clutch (flywheel and plate, no need for a bearing or fork etc.) was instaled it would turn the torque tube and still dampen to a degree(springs on clutch plate). If there is reason this would't work coud someone please tell me.

I don't understand why the car even needs the damper. I'm just looking to get the car back on the road asap.

Are you thinking of replacing the torque converter with a clutch or having a clutch in additon to the torque converter...? Or have I got that completely wrong?

The torque converter is in the back of the torque tube, the clutch would be installed in the front just like a standard trans car. There would be no reason to have to disengage the clutch, it's just there to act like a damper and turn the torque tube.

This is just one idea I had. I REALLY need this car back on the road.

OK, having looked at PET I think I see what you're trying to do.

Yes, in principle, what you are proposing will work.

In practice, the difficulty will be in finding the right parts that will fit in the space and will interface to the input and output shafts...

I remember reading about a similar situation a while back.
Here's a thread which may help:

Why does it need this damper? Can it be welded solid?

Could you convert it to a manual?

There's a thread about this over on pelican right now. Someone is fixing their auto tranny 924, and the discussion centers around whether they should install an original part auto dampener or replace the dampener with an actual manual transmission clutch in place of the dampener (this is not changing to a manual tranny...)

Might be worth checking in there...

I would love to convert it to a manual, but I would need the parts for that also. Anybody have what I need for that?

I think the idea is to use a rubber-centered clutch plate for a dampener instead of the actual auto-tranny dampener part. Much less expensive but retains the auto tranny for shifting.

Check the other thread....

This is what I decided to do. I'm going to Advance Auto today and buying a 90 VW Jetta clutch and pressure plate. I'm told it will fit the 24 tooth auto torque tube; It is a 1/4 smaller than the normal N/A cluth but a lot cheaper and like I said it would never be disengaged. I should be able to getting to putting this in by the weekend I'll let you know how it turns out.

Before you go to all this work,check what the clamping force is on the vw clutch.Then find out the clamping force of the porsche clutch. If the vw is less you might end up with a slipping clutch if it cant hold the torque from your porsche.Just a thought
