Sounds like low oil level to me, possibly leaking from the gearbox plug connector seals. That'd be first place I'd look anyway.

Is this a 5 speed box ?
It sounds like it has gone into 'limp home' and locked in a low gear.
I suggest you get a read-out of fault codes to pin-point which part is causing it, assuming the earlier suggestion of low oil level is not the answer.
