Although I am on the other side of the world maybe I can offer an explanation re the repair of the box as opposed to complete replacement.

You guys have obviously had the parts made available sooner and hence the OPC's requirement to "rebuild" as opposed to the previous situation of "replace".

The OPC said they used to just replace the whole box but now they have to repair them?
Replace whole box (for a factory reconditioned one)

Suggestion
At the moment in Australia, if you have a gearbox problem they still have to change the whole box (for a factory reconditioned one).

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Popped to the indi to ask about a rattle I have in the car when neither accelerating or decelerating but that stops when you press the clutch in.
Never mind the rattle he said after 10 yards-its the whine thats a problem. Get it to Porsche because you have the warranty. You need a new gearbox. There is a bearing that has or is in the process of collapsing.
Off I go and they say we havent got a car for you to use-why dont you drive back down the road and call Porsche Assist. So I did and now I have a Merc and my car is in OPC Chester.
So, could the whining be caused by anything that WONT be covered under the warranty? The OPC said they used to just replace the whole box but now they have to repair them? Any ideas?

Phillip I would be amazed if the anything in the gearbox isnt covered by the wtty,
dont worry buddy it will be fine.
Migration info. Legacy thread was 128551
Sorry to here that Phillip. You ain't having much luck at the moment with the car are you?
However if anyone is considering whether to have a warranty or not, I think this should answer it.

Don't know if this helps, but that's exactly what I had in my 993. Turned out to be the diff bearing had exploded, wrecking the diff. Needed new diff and gearbox rebuild. Hope it's something straight forward mate.

Dont know how long. They cant even look at it till Friday. I guess that if it was just a new boc its a quick job but if they insist that they want to mend what is briken they will have to strip it down which will take ages.
Is there anyone that I can call to ask if I can have a new box ?

Philip,
Although I am on the other side of the world maybe I can offer an explanation re the repair of the box as opposed to complete replacement. At the moment in Australia, if you have a gearbox problem they still have to change the whole box (for a factory reconditioned one).
I have been offered this explanation:
With the 996 the gearbox internals were produced by ZF under licence from Porsche (unlike previous boxes). ZF was given the job on the proviso that they were not to supply any parts to people requiring them in the event of a worn synchro, dogteeth etc. You essentially had to go back to Porsche who would fix the problem (new box) and hand over some serious cash - essentially a money making exercise. This sort of stuff is not limited to gearboxes apparently (I have a rattling strut plate at the moment which essentially requires a new strut unit - you can't get the plate alone I'm told.
I have been told that Porsche were looking at beginning to supply parts for the rebuilds however we are yet to get anything down here and I know a lot of the indies are trying to contact companies overseas who are fabricating their own parts as the cost of a new box for a car out of warranty is approx. $16k aussie (from an OPC) and seems a hell of a cost for say a dead synchro or dogteeth problem. The comparatively cheaper rebuild will set us back about $3k.
Maybe a number of cars under warranty have been coming in and Porsche have decided to start supplying parts as although they don't make as much money from the poor blokes like myself who are out of warranty, it will cost them less in the event of somebody having this problem with their car still being under warranty, i.e. your situation.
There are a number of 996's (including mine - dead dogteeth ring although very minor), Boxster S's crusing around over here waiting for Porsche to make parts available rather than having to fork out $16k for a new box.
You guys have obviously had the parts made available sooner and hence the OPC's requirement to "rebuild" as opposed to the previous situation of "replace".

Popped in today, mainly to tell them NOT to wash the car. The girl was really on the ball. She said they had done an extensive road test and they can hear noise in the gearbox. Next step is to drain the oil and inspect it to see if there are any metal particles in it. More updates when available!

Had a call today. They drained the oil and found lots of shiny metal bits (swarf??). They are going to strip the box and see if its more economical to fit a new box or fix it. We will see!
