I was having a look at this again on Tuesday, I released the plug a couple of times and the spring fell to the same spot each time and I can't see it moving from here once everything is in place even if it has been driven. I have the metal plate back in place again now and it sat behind it each time.
I also removed the plug where the spring sits and it gives good access to seeing into the lever arm area. I would be still tempted to try to fish the spring out or just buy another one.
My circlip was corroded that only one end was left on it and I had to pick it out with a screwdriver. Luckily I had a box of circlips and some the correct size.
The pivot arm sitting as yours is.
Down the spring hole and you can see the pivot arm.
By moving the selector I could line the arm back up, this was with it sat back on the bearing with the spring in place, probably easier said than done with the box all in one piece.
If I couldn't fish the spring out somehow, I would remove the box from the car, with the box flat on the bell housing, only split the casing a couple of centimeter and try to remove the spring at this point, or remove the circlip and use a new spring.
You don't want to split it much further than 20mm as its a nightmare to line all the selector arms back into place. You will need to then seal the joint with a good sealant, I use engine sealer Loctite from OPC. _________________ http://euroroadtripper.blogspot.co.uk/

Did the spring retaining cap come out easily infrasilver ?
My endoscope is about 8mm diameter at the camera and has a hook attachment you can fit for fishing things out like this, do you reckon you`d be able to fish the spring out with that

It came out reasonably easy, I did punch it up and out from below so I could re-use it though as I didn't want to go ordering another. But following the Porsche procedure for removing it previously shown, I would guess it would come out easy.
If you look close you can see the cap has got a rubber gasket around it so won't corrode around the edge where it meets the gearbox casing. The endo' would possibly go to where it is sat in my picture, if it fell any further I would guess it would be on the magnet at the bottom of the gearbox anyway so could be removed by draining the oil? _________________ http://euroroadtripper.blogspot.co.uk/

Also with the endoscope you could probably get to it easier through the oil drain plug hole, it would be closer to where it has fallen to I would guess? _________________ http://euroroadtripper.blogspot.co.uk/

OK,my endoscope was £70 from screwfix, it may be worth Grey996 getting hold of one and having a looky see before dropping the box, if I were closer to him he would be welcome to borrow mine
This camera does actually do video out, you just need an AV input on your laptop, I have an old Sony Vaio that I use for stuff like this, along with my 7, yes, you read that right viewers, 7 other laptops with specific uses in my work

Thanks again, there’s still hope
I bought a camera for this, mines an 8mm and has a hook attachment too so i’ll drain the box and go fishing. There looks to be some baffles at the bottom which might impede things but i’ll try.
I’m very doubtful about getting the spring back in with the box in situ but i’ll see if the camera helps.
I’ve recently rebuilt the box on one of my old Alfa’s but by the sounds of things I really could do without splitting this one! _________________ 2002 Porsche 996 C2

I believe you are in Sheffield, if you want to have a poke around gearbox insides at any point to see what they are like first hand, Infrasilver and myself are both based near J26 M1 so not far away.

Nightmare! Nothing to add apart from good luck with the camera etc.
Such a simple error that can cause a massive headache. Exactly the type of thing I’d do, that.
Well done to the usual suspects for the excellent info and help. Great stuff.

No joy unfortunately, can’t get the camera up and past the baffles.
A mate who’s into Land Rovers came round and I told him I needed to take the box out to access a plug at the top of the box and he said why don’t you just cut a whole in the floor, I did think about it for a few seconds _________________ 2002 Porsche 996 C2

You are welcome round to look but I think you have seen most of what you need to know from the pics but if it helps get your head around anything feel free.
I don't think there will be any baffles in there just the gears from the output shaft.
I was wondering if you'd poked your finger up into the drain hole and towards the bell housing, I've updated my picture below to show the red circle where the magnet sits and if the spring has made its way down far enough it may be on the magnet, the orange blob is around where the drain plug is so you should be able to feel the magnet. It'll probably have a load of grease on it from the sealed bearings though and hopefully a spring.
I do think there should be enough space to get an 8mm scope through there and up a little way but it depends on the angle you can get it in at I suppose? _________________ http://euroroadtripper.blogspot.co.uk/

Thanks, yes I can feel the magnet with my finger but the spring isn’t there. It’s frustrating as I can get the camera towards the front of the rear of the box no problem and can see right along the gears but I just can’t get it the other way and then up. The camera is only 8mm across but it’s about 25mm long so it’s not as flexible in tight spaces as I need.
It’s back on it’s wheels now as I’m taking it down for it’s mot so we’ll see how that goes first! _________________ 2002 Porsche 996 C2

I had decided to wait until the Christmas holidays to tackle this but phoned Revolution to see what they said. They have done a few of these, said it can done by fishing the spring out and lowering the box enough to access the top plug but he said it’s probably quicker to drop and split the box and check nothing else had happened. Quote is 5 hrs labour which is £430.
I’ve never been totally happy with the shifting despite a new clutch, 997 shifter and new oil so I might take it in for a chance of a good going over. Plus it looks like the RMS could do with changing too. _________________ 2002 Porsche 996 C2
That’s pretty much what I’d do too, if you think of it as the box was going to need to come out in the near future any way for other work then the majority of the labour is free!
I personally would only get them to take the end cover off, refit the spring and lever correctly then give it a once over to make sure the loose spring hasn’t done any damage, and put it back in with new oil

Maybe a good opportunity to tackle some other related bits and bobs too, eg The brake lines that run over the gearbox _________________ "911- the guilt-free supercar"
