OK so further to my post, I need some advice. Any gearbox gurus on here?

My gearbox has been pretty noisy for some time. Making a wirring, sometimes spinny, grindy sounding noise.. (How do you describe a noise ha) Anyway I took it to the gearbox guy today and putting the clutch in and out, and hearing the different noise it made, he is adamant it has at least a broken tooth in there somewhere. He also said a broken tooth can cause more broken teeth and if it throws a tooth on the road it could lock up and lock the car up.. He was very sure I shouldnt be driving it anywhere.

So no good!

Thing is, Ive been driving it around for a while with the noise and took it to bacchus Marsh last week. Im reluctant to miss out on hanging rock with the sandy! What do you blokes think? Is there a chance the gearbox can lock up? Does this happen?

I know the answer. The answer is who knows, and of course theres a chance and I shouldnt drive it, but I just thought someone might be strongly of the opinion that itll be fine! ha..

Anyway, So maybe no cool car for me but Ill be there anyway...
