Not sure what to call this so it's hard to search for on the forums...

I don't think I have any grinding problems other than the common 1st into 2nd sticking when the transmission is cold (I also knock, not grind, but knock into 3rd gear sometimes when it's cold, but that could just be my shifting)

Anyways, the main problem seems to be when I'm in 4th or 6th gear, but mainly 6th, on the highway, I can hear a grinding sound, sort of like when your brake pads are finished and the metal on metal grinding you hear when the wheels are spinning (or like if I took a piece of metal and dragged it on the ground when the car is moving).

My friend asked if 2nd, 4th, and 6th were on an independent shaft and that it could be the bearing for said shaft... Dunno really what he meant by that.

Anyone else know what it could be?

So my problems are:
-1st into 2nd when it's cold takes some force to get it in (doesn't grind unless I force it in the wrong way)
-2nd into 3rd makes a knock sound when it goes into gear but that may just be me being to forceful on the shifter
-I wouldn't say going into 5th and 6th is like butter, but there definitely is no sounds when I go into those gears
-All in all, I don't hear any sounds going into and gears, only a grinding sound when I'm already in 4th or 6th gear and driving

For your knowledge, I put in Redline MT-90 at the start of this season (April) and plan on flushing and doing so again next Spring, and I'm running a short shifter so noise levels are little higher from the center console.

Thanks in advance!

 

USe Mobile One instead.
