Missing Trans Mounting Bolt

My 2002 Boxster Base is missing mounting bolt G as shown in the following pic, and it doesn't look like it was ever there. Did the factory not install that bolt in some year/models?



Thanks

I noticed the same on mine. If I remember coorectly, the missing bolt threads into a hole on the transmission that does not even thread into the motor. My guess is the tranny case is probably used in other applications (VW or Audi) that used that bolt hole. I may be wrong, so give it a look and see what you think.

Could it be that bolt G is used on a Tiptronic transmission?
IIRC, Wayne's project car for most of these tech articles was a tip.

The engineers probably discovered that it caused a stress riser in the engine or tranny castings and omitted it to save it from cracking/failure.

I would not install that if it is truly an omitted part.

Need to get an official answer on that from Porsche just to be sure.

If it ain't broke don't fix it, else it WILL break.

I wonder if it was omitted by someone earlier who found it hard to install it and decided to omit it as there were many other bolts. I myself struggled with that bolt removal and reinstall and ended up not torquing it but just as tight as I could.

Omitted on my transmission as well. Mine came from the factory like that. Dunno if it's a difference but my car was the Valmet assembly.

i think, that the guy that was responsible for assembling the transmission, was not professional enough. he probably got hired just because his uncle had some contacts.

is uncle, by the way, is Hans Blödsinnig. the engineer that designed the IMS the AOS and the coolant tank.

Actually, that bolt would be one of the easier once to access. And, the transmission on my car had never been out.

I'm still betting that it's used on the Tiptronic transmission.
