Thanks for the replys,
I now know why I have no drive. This is because the gearbox keeps pushing the drive shaft out. I have had a new one put in, but the gearbox still rejects it.
So looks like i'm goner need the gearbox looked at. I'm told it is probably to do with the planetry gears. So I will have to face the expense and get a gear speacialist to look at it.
Is this a common problem in MG ZR's does any one know? or does any one know a likely cause for the gears to fail in a low mileage gearbox?
