I bought a speedo drive seal from GPR last week and it looks like the shifter seal only smaller. The haynes manual shows an 0-ring. Does anyone know which is correct before I try to replace it. The part number I have for the new one from GPR is 999.113.036.50.

Here is a crappy pic.

There are two seals: an O-ring that seals the drive housing to the tranny case, which you can see when you remove the bolt and pull the drive out of the tranny, and a seal (which you already have) that seals the rotating shaft. You can see the seal when you unscrew the bottom half of the drive housing from the top half.

I can look up the number for the O-ring when I get home in a couple of hours. I know Pelican has the O-ring, but I don't see it on their site. It will come up if the Porsche part number is typed in though.

O.K. The O-ring part number is 999.701.084.50

Pelican should have them. That's where I got mine from.

I don't remember any seal but the o-ring on the speedo drive.

Maybe it goes in here?

Yes. The seal you showed goes there. Unthread the two halves and pull the shaft out.

Mine seems to be a bit loose at that point. Could it be coming unthreaded or the seal going bad??

OK, so... if those 2 seals are replaced will it stop the leak?

Swood... did it work??? no more leak'n???

What I saw when I pulled it apart was that you can't replace the internal seal unless the machined casing can be split open.
