all you do is pull the trans out of gear as you let off the gas and the gearbox unloads, and gently hold a LITTLE bit of pressure on the shifter and when the rpms match it will just fall into gear. its pretty cool. you can downshift like this too but i dont usually.
In the Miata, that's probably gear lash, and there's nothing you can do about it. It's faint when the car has full interior, but take the carpet out and it gets loud. Put a lightweight flywheel in it and it'll be almost unbearable. I replaced two transmissions, throwout and pilot bearings, and tried different tranny fluids before finding an article about the real cause of the noise. In the end I had to put a loud as hell exhaust on my previous Miata so I couldn't hear the damn tranny clattering.
