symptoms: won't slot into gear nicely while moving (harshly, to the point i feel like the box is going to drop out from under the car), or while the engine is running, both with the clutch depressed. will slot into gear when the car is off with the clutch in, not without it ever.
but when it's cranked over, there's a fine zzzzzzz noise (you know what i mean) finer than the noise you hear when you watch someone grind there car's flywheel away trying to start it when it's already running, but similar sounding.
just drove back from melbourne, 5th gear, 100-120km/h no worries.
first time i try to downshift to third to take a green turning arrow (roughly 50km/h) coming into Geelong, it's like i'm pushing the shifter up against a brick wall, roll to a stop in the middle of the road.
push off to the side. wait for a bit, then use the above method to get started again. taking off, crunch it into second somehow, cruising along at 5000rpm in 2nd, trying to not have to stop the car.
forced to stop at a round about, nice lady in a tarago (who said she has an mx5!) helps me move it off to the side again, big thanks to her. then get going again, using the aforementioned method again to get moving.
miraculously get it into third, creeping it home from the other side of town (usually a 15 min. drive), have to stop a further two times i think, getting it going the same way as before.
and pull into home.
*sigh*
i'm not very experienced when it comes to cars and their issues, so do you guys think this sounds like a simple worn (broken?

help would be great to narrow it down for me, as i'll take it to a mazda specialist through the week.
thanks.
