When you say grind, what do you mean

Does it make a grinding noise or is it just hard to get into that gear

I noticed on my car, sometimes it is hard to get into 3rd gear or 2nd even though my clutch is.

So while i'm driving mostly down shifting into 3rd gear, it grinds even though i have the clutch down all the way

The grinding noise happens while i'm throwing the stick into 3rd gear.

I have approx 750 miles now and i'm experiencing 3rd and 4th gear grinding even when the clutch is depressed all the way

Using thicker transmission oil can help, but it's a common problem on z's

Just take it easy when shifting, maybe even double clutch if you're downshifting to 3rd.

I’ve been looking through a bunch of forums, here, and youtube comments concerning third gear grind and methods of fixing it without replacing synchro/transmission.

I have a 2003 and i’m having trouble with my third gear synchro what are the best choices

My 2003 350z has bad transmission synchros, this is a very common problem for early year 350's and g35's

I picked up a used transmission that had no issues and replaced it.

Stock synchros are notorious for grinding, causing pop outs and lockout during high rpm shifting

Eliminate all of these issues with the synchrotech carbon.

As others have said, bad synchro's

A new trans direct from the nissan dealer should be about $2k

Do not use redline trans oil, though, unlike some of.

This is a 2003 nissan 350z track edition

The video was recorded before the vehicle was dropped off at a dealership for diagnosis.
