Yep mine had a similar problem, got it sorted with a new gearbox.
Can you get gears with engine off.?
No- shagged box mate.
Was quoted 1000 for a rebuild.
Find out your gearbox code its on the top of the bell housing on the nearside of I remember be something like ty752vn3aa.
If you have a ty754 box get hunting they can be hard to find. You need to match the code up with a new one. Or you'll be in trouble.

Yeah mate that's what mine did, if it's a my99 it's probley a ty754vn1aa, like mine. Got mine from a breakers. Drain the oil, I had hand fulls of teeth.
Did you get your box out? There's a big Allen key cap in the side of the box, undo that, 12mm I think, get an m6 bolt 10mm head if I remember, screw that in the hole and give it a yank, pull the bar right out. Your box will come out. Don't think I forgot anything.

Blimey ty754's are supposed to be stronger. Also to help a bit more (NOT) that gearbox number has no info in the transmittion chart!!!! If not sure of ratios etc just make sure you get gearbox and matching diff. I'd imagine somebody on here knows diff ratios of your car and maybe someone is selling one to fit yours.
