Been a while, wanted to give an update:
So, I shaved down my clutch teeth after cleaning my input shaft spotless and it still wouldn't work, so I bought a new trans. The clutch I had fit perfectly so it was a warped/twisted/something input shaft on the one I had previously.
Bad News:
The new trans works great, every gear shifts smooth and works correctly but it has a strange humming noise in neutral with the clutch out (clutch pedal not pressed), as well as a whining noise that increases with speed and it's pretty loud. When I was putting my clutch fork and things onto the new trans I noticed some whirring type noise when I spun the input shaft by hand, but didn't think much of it at the time since I'm not too familiar with transmissions (if you guys haven't noticed). Im gonna give replacing the input shaft bearing a shot next week or the week after and I wanted to know if any of you have done anything similar, especially if there's anything I need to look out for while doing this.
Good News: The car at least drives, the clutch doesn't slip, and the trans works as it should besides input shaft noise.
any tips for when I open up the trans are much appreciated
