3/4 shift fork is a common issue. Most people just get a used transmission and swap it, but an upgraded shift fork is available, though you will probably have to get it from Mazda. I think it's around $50.
The 03 zx2 has the upgraded shift fork from factory, but the gearing is a little different from a sedan.
As far as DIY pulling the transmission I have heard escort transmissions aren't too bad, but still haven't pulled mine yet.
