I thought the same on my manual tranny with 185+k on it. It was fighting me with all the gears, and I would really have to shift at the exact rpms for it to go into gear. Similar to clutchless shifting, like on a big rig, but of course I used the clutch. Not only that it would be really tough to get into first gear from a dead stop, or into reserve, having to force it in hoping I'm not gonna bend the shift forks. And with the tranny having 185k I just thought that it was pretty much at the end of its life (maybe had a rough life with previous owners who had no idea how to drive a manual) and needed to get another one. Anyways yesterday I decided to just go ahead and replace the fluid (unknowable if its ever been changed in its life) and picked up some mobile 1 synthetic atf (yes the M50D takes atf fluid). Well after changing the fluid my transmission shifts alot better. However I've only driven it for maybe an hour total, so it could be that the problems I had before may reappear after 1,000 miles.
As for rebuilding, the M50D normally gets quoted for around $800 for a rebuild. And when your doing that you need to replace the clutch & etc.
Another option, is going onto
http://car-part.com/ and finding a local parts shop in your area that has an M50D tranny. A grade "A" tranny with around 60k are normally priced between $500-650.
Edit: Just noticed you have a '89 with the 2.9L, I believe you could either have the Mazda M50D tranny or the Mitsubishi 5spd. So your just gonna have to look up the price on that one.
Warning: the Mitsubishi 5spd takes NORMAL gear oil, however the Mazda 5spd takes Automatic Transmission Fluid so find out which one you have before your change the fluid or buy another tranny.
