Feels rough shifting + 6th gear ringing. - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

I got this car used and it's my first manual car, so I'm not sure if it's all ManTran cars or just this car, or me.
When I shift, usually to third or fifth gear, if feels like something is in the way of the shifter itself, not lower, but where the rod of the shift stick is right under the boot. It makes sort of a crunching noise sometimes. This happens like 75% of the time I shift into third and about 30% of the time I shift into 5th. No other gears really have this sound, though it does feel rough shifting into first or second sometimes, but I read that's normal.
I asked a couple of friends and they said it doesn't sound anything like grinding.

Also, in 6th gear around 3.1 - 3.3 RPM, there's an extremely high pitched sound that comes from the engine bay. It goes away as I speed up but comes back/gets louder as I near that RPM range and it's ONLY in 6th gear. It gets a bit annoying since around 70MPH, it's pretty prevalent. Any idea?

How many miles on the car? I bought my brz with 18 miels and I feel like my shifter got better/smoother with time.

As far as the noises when shifting gears.. Make sure you are pressing the clutch all the way

Are you sure it's 6th gear doing the ringing? The noise may be coming from the differential. After I installed diff bushing inserts, I get it at 35 and 70 mph. I "solved" it by cruising a few mph higher or lower than 70. It is kinda annoying though.

It's only happening in 6th, no other gear

did your noise come on at any gear?

It's 30k miles.
I tried anywhere from pressing all the way in to pressing in softly to almost all the way to the wall, etc. It still happens randomly.
