when im driving my car sometimes it will grind into a gear, it wont make an noise it just feels like the shifter hit metal but goes in fine, for a while i was thinking maybe its me not keeping on the clutch but i have it down like crazy and sometimes it will grind, latley i've noticed if i shift softer but faster its cool but sometimes it will grind anyways, its basically i just feel a shock from the shifter, got a downpipe imj scared to take it to the dealer.

my clutch also when im in first and im at 3k and stop at a red light and then it will make a loud squeek noise. any help would be appreciated, i was thinking of trying a quart of syncro mesh or redline shockproof.. any suggestions.

i also around 3500 rpms i hear a loud rumble coming from the shifter

please help, thanks

 

If the grinding feel comes from the same gear everytime you feel it, then what you're describing sounds like the beginning of syncro going bad. It starts as something that is only felt, then, as it gets worse you can hear it everytime you shift into the affected gear. I would recommend taking it easy on the shifts, as this is something that can only get worse. I have a 3rd gear syncro going out on one of my WRXs, and if I wait a second or two after pressing the clutch before I shift into 3rd, it goes in smooth. Hope this helps!

As for your "squeak" problem, I don't really know what that could be. Does it happen when the clutch pedal is in motion?
