hello /o/
i have a 6 speed manual and every time i go into 6th (and now 5th which just started recently) it grinds unless you granny shift
currently it is still able to go into those gears but the sound is very prominent
i heard online that it could be worn synchros and it's kinda making me anxious because that could be very expensive
i am coming up on 120k which is a multiple of 30k so i'm most likely due for a tranny fluid change but i'm not sure if it will change anything
yes i always press the clutch all the way in and yes it disengages so that isn't the problem
could anything else be happening or am i in for an expensive rebuild?

just start double clutching like you should be

Flush and fill won't fix it, as was mentioned it's your synchros.
And I cannot stress this enough, make sure you have someone who knows what the fuck they are doing rebuild it. It is extremely easy to mess up something very tiny in a tranny rebuild and end up with an intermittent grind or other odd problem.
Alternatively, it might be cheaper to find a replacement tranny from a wreck with less miles than yours and install that.
Good luck!

wouldn't that just cause more grind because the tranny gets spun up from the clutch being engaged?

Can't hurt to check your clutch pedal adjustment

make/model? if its only one gear you're hoping it a linkage issue or a weird master/slave issue. If its easy you could always try changing your slave cylinder or bleeding your clutch and seeing if that does anything.

Ignore him, double clutching is a meme and only done by autists who think they're Dagumi and drivers of 60s trucks with no synchros.

the synchros are already 100% gone.
what you're hearing is the dogs on the gears getting worn down to shit.
>is it going to be expensive
I pity people who don't work on their own cars.

Slave cylinders are easy as fuck and G/Z's are known for having slave issues. Try a new slave cylinder and bleed the clutch system.
My G35 is notchy as fuck into 2nd and 3rd when its cold outside (0F or colder). Before the engine is upto temp, I double clutch into 2nd and 3rd.
Anyway, sounds like you need a rebuild. Or just double clutch and/or granny shift into 5th and 6th all the time.
