IIRC there was a synchro upgrade in '95 or '96 ? But in any case the main
shaft gears are usually poorly/carelessly aligned (longitudinally) with the
cluster gears. The result is less-than-full-length contact between the
teeth so the maximum possible strength isn't there. Mazda thinks this is
just fine since the trans was designed for a V6 RWD sedan and is being used
in a much smaller, lighter, less-powerful vehicle. The original design
strength can usually be restored by re-shimming the gears on the main shaft
to align them properly. I doubt that there are any of the old RWD sedans
around (most of the cars imported here had automatics) but if you're lucky
enough to find one it would be a much better donor vehicle since their
trannys were assembled to a much tougher spec.

I believe 94 and later are a little better for things like not getting stuck
in reverse. None are stronger.
Go to Miata.net and check the used parts guys. There are a bunch of them
there.

I need to get a replacement tranny for my 96 1.8 ltr. This is going on

Are there any differances between the early and late model year
transmissions?
Are there model years that are beefier to handle extra engine torque?
Thanks...Steve
