My car has a loud whine when the clutch is out due to the previous owner not having enough fluid in it. I changed the clutch and throw out bearing and still have the whine. I suspect the input shaft bearing to be doing this ? Anyone know what bearing is the cause of the whine ? Could i just split the tranny and put a new bearing in without a total teardown and reassembly ?

Most likely all the bearings in the tranny are toast. Input, cluster, etc. I have been through the same thing, and the only cure was a rebuild. I personally won't tough a tranny, but if you can handle it, then go ahead. Be aware that there are a number of "special" tools needed.

I figured most of the bearing would be shot. I can get a tranny with 97k miles on it for $250, which isn't too bad so i think that i'm going to do that. Whei pulled hte tranny at most i bet that it had 3/4 of a qt. of fluid in it.

I re-bearing ed the 5 spd in my 88 last winter myself.
The bearings, input to main needles and main shaft bearings cost 250 from mazda dealer. not a hard job, just takes time and very careful dis-assembly. If you have a digital camera, take pictures while you're tearing it down. I had two of the forks mixed up initially. And no you can't just split it to replace the bearings. It a nicely designed tight tranny with the gear clusters very close together. By rebuilding it yourself, you'll be able to end up with virtually a new trans that shifts really smooth, even under high rpm racing.

Rebuilt mine a few years ago. Digital pics are definately useful. Along with bagging the parts as they come off and marking on them with marker showing direction. You can get a better deal on the big bearings at a bearing supply store. The needle bearings and lock nuts buy from dealer.
