First post here - hoping someone could help.
Was out driving tonight, going around a rather large round about, changed from 2nd to 3rd and the gearbox seems to have slipped in some way. Now, the car is permanently in 1st, (you still have to clutch it in and out of gear) however moving the gearstick does not change gears - it simply slides up and down like it isn't connected to anything. It can move from 3rd down to 4th but that's it, it doesn't seem to engage anything, nor can it move to the sides, even with some force it is stuck in the central column.
I managed to drive it home in 1st with the hazard lights flashing (rather embarrassing

Any idea what may have caused this, and any clues as to how it can be fixed? Any help at all would be reeeeally appreciated, I work full time so its hard to call around to car yards and I'm worried about my transportation a little now too ...
Cheers.
