I've had some of these problems for a while and some just recently started happening but I finally got off my butt and decided to ask what I need to do to fix these annoying problems.

First off, when I push my clutch in it makes a squeeking noise. Happened recently, only squeeks when I push my clutch in in neutral going to first.

Sometimes my car won't go into first gear, I have to take it out of gear and push the clutch in again and then it will. My shifter will go halfway into first gear but will not go all the way in until i take it out of gear, let go of the clutch, push the clutch back in and then put it back into gear. It gets SO frustrating

Also, when i first start my car and start going in first or reverse, after about 3 seconds of driving the car makes this sorta buzz noise really fast. It happens EVERYTIME I turn my car on and drive after a few seconds. I can turn my car off and on 100 times and it will do it every single time. It also does this when I hit a pothole really bad.

Lastly, when I have my clutch pushed in and i'm in first gear and I start releasing my clutch and getting on the gas, it SOMETIMES makes this sound as if metal is touching metal pretty loudly. It mostly happens when I'm on a hill, it's annoying as hell and definitely sounds like somethings wrong.

Any input would help tons, thanks guys.

Oh yeah, my car is a 5th gen SH if that helps at all.
