Alright, I'm definitely gunna do that. I've put about 6k miles on it. Now that i think of it when trying to shift into 3rd kinda quickly it sometimes will grind for seemingly no reason, and also grinds going into reverse everytime no matter what?

That's an old and abused (by that I mean driven spiritedly) transmission for you. If you want to TRY to get rid of that, find a low mileage replacement. Good luck though.

Concur with this and what your mechanic said about worn sychros WRT 3rd gear, but the grinding while shifting into reverse sounds like it could also be an issue with the hydraulic clutch linkage. Problems there can lead to grinding in any gear, as the clutch may not properly engage/disengage as it should. Look for signs of fluid leakage around the clutch slave cylinder, especially on its rubber boot - if you squeeze the boot a little and fluid leaks out, it's shot.
