996 tiptronic problem - help please

Out for a drive today in my 1998 3.4 tiptronic, everything absolutely normal but then as I went round a left hand corner and accelerated the engine revs went high/screamed and I lost all gears and had to coast to a stop.  No warning lights, engine starts and runs okay but it just won't engage any gears including reverse and no difference on manual. 
The gear selection does show on dashboard but it's just as if it was in neutral or what you'd expect with a clutch depressed. Where it happened I did not find any oil on road or other debris from my car.  Because it happened on a Sunday I had to have it recovered back home.
 
Has anyone any ideas as to what may be the problem and do you think I would be best putting it into a main dealer or would a good independent be the best bet?
Thanks in advance.

    Can't really help with diagnosing the fault. My first instinct would be to check fluid levels and then change fluids and filters in the transmission. Sounds very weird to go completely like that...
    Regards main dealer or indy, Personaly I go for an indy. Northway in Reading gets my vote (location dependent of course!)

    Thanks. Had various suggestions now. These include fluid levels, oil pump, drive shaft, relays, multifunction switch. Spoke to my normal indie this morning and car is going to  be recovered to his place (JGC Brackley) hopefully on Wednesday for a proper look and diagnosis. Will post eventual diagnosis on the forum in case others have same problem.

    My Indy has been unable to identify the fault and believes it must be something gone wrong within the automatic gearbox but even if taking out the engine and gearbox he will not be able to repair it and I'll need to get it sent to a specialist.  Can anyone recommend a good automatic gearbox specialist in the Oxfordshire or nearby area?  Thanks.

    Thanks Mark.  Presently phoning around the various specialists.  No one seems to have had problems with the tiptronic box and it seems I have just been unfortunate.

    DSteve,
     
    Have you contacted Nine Excellence? They’re in Surrey and their website says that they have experience to diagnose and repair Tiptronic transmissions.
     
    The Tiptronic trans is a conventional ‘slush pump’ auto so a general auto transmission repairer may be able to assist you if the problem is purely mechanical.

    I had issues with my Tiptronic box a couple of years ago and 9excellence were brilliant in sorting it - I cant very recommend them highly enough.

    Thanks very much for the suggestion.  I have been looking at a couple of possibilities, STA in Aylesbury and AJ Automatics near Dunstable.  But its good to know of somewhere someone has actually used and I'll give them a call.

    Thanks. STA were on my shortlist but after a personal recommendation the car is as of yesterday at DW Performance in Wellingborough. Hopefully it will be sorted out in the next week or so.
    When I finally find out what the problem is I'll post it here in case anyone else has this issue.

    Hi Steve 
     
    Any news on your situation ? This gearbox is a very common Box , it's Actually a Mercedes Benz gearbox and are normally quite diagnosable , there are so many reasons for this but this should be relatively straight forward to pin point , A diagnostic Actual values check and system test should show up where to begin . It's providing the fluid pressure is present at the valve body then it could be just a solinoid valve . But like I said it could be a number of things , lets us know how you get on .

    Hi Mark
    The gearbox is a ZF automatic and apparently the problem was a broken main input shaft!  A new part is  now installed and the box is back together. It should be installed and tested ready for collection next Wednesday.  Not sure exactly how the shaft  broke and I'll asking a bit more about it when I pick the car up - and posting it here for the info of others.
