Mitsubishi Repair: 1999 Manual Transmission Noise, clutch plate, clutch pedal

Question
I recently purchased a '99 Eclipse, 2.0, manual transmission, non-turbo. A month later I experienced an immediate chatter/rattle noise every time the clutch depresses. It mostly clears when released, but intermittently chatters during mobilization. We replaced the clutch/throw out bering and put it back together with the same results. Pulled the tranny & took it to a professional who indicated bad internal berings/gears and a cost too excessive to rebuild. Bought a used tranny with <100K on it (6 mo warranty) and installed with the recently purchased clutch/throwout bering... Same noise still. I should tell you it sometimes goes away for brief periods. Tranny fluid is up to snuff. Mt son and I are racking our brains and becoming experts at pulling/reinstalling transmissions... but i'm getting older! Any suggestions would be greatly appreciated!

Answer
Buddy,
It sounds as if your clutch is not fully engaging when the clutch pedal is released.  It's possible that your clutch plate is not aligned properly.  It's also possible your starter motor is interfering. Make sure your axle splines are not over worn and making proper contact.
Good luck!
