Okay here's the latest, thanks Mantaman and Rick-Manta for your help. The exernal linkages etc on the vehicle all appear intact, the vehicle freewheels in all gears as if they don't engage however it does stop in park (it's an autobox) I didn't hear anything crunch or snap when it went, it was just like it went into neutral. Does anyone know what it might be so I can check it, I have it in a garage at the moment which is incurring me costs however i don't just want to give them another paid ticket to changing everything they fancy so if anyone knows exactly what is wrong then I'd be more than grateful to hear from you. Could do with a specialist manta garage really as vauxhall wont touch opels even if they are current models... something to do with insurance I was told, although these days with all the electronics and diagnostics etc I doubt they would have anyone with the knowhow to deal with simple cars :-p. I have been told that the torque converter appears to be in working order. If it is the gearbox does anyone know if it is just a part that could be replaced? Also how hard would it be to take care of all the changing etc myself?
Many Thanks again and I look forward to the replies.
