I've got an appointment to take mine in next Tuesday at 6pm. Stupid 6th gear still grinding away :(

Maybe you jumped a tooth!
D:

how exactly does one go about grinding a gear... like if they wanted to do it on purpose. i dont really understand how someone grinds the gears in their car.

Damn Nissan gear box, it's so damn clunky is scares the hell out of me even when it's acting normally. Thankfully the clunk differs from a grind.

Leave the clutch unpressed and move the shifter towards a gear.. it will grind like crazy.

Problem is when the synchros go bad, you can't stop it from grinding (unless you wait seconds before completing the shift)..

The G35 coupe gear box is worse than the 370Z's.... No issues for me so far...

i've noticed that mine grinds from 6th to 5th on a downshift at highway speeds every so often, makes me grimace every single time, wonder whats up with it...

How many miles is everyone having these issues? As reported, mine was at 10k

I first noticed it at probably 500 miles and by about 3000 miles it was to the point where I can't skip 5th if I don't want to grind 6th and I have to shift slowly. My car is at 8500 miles now.

Very good question.. I started noticing problems at 8-10k.. didn't take it in until about 19k when I couldn't NOT shift 5th without grinding..

Then I was obviously aware.. had issues at 12k.. replaced.. then 15k.. kept taking it back.. took a couple visits before they would warranty on each occasion.. but ultimately it was evident that it wasn't me doing something wrong.

Now I'm technically out of warranty at 98k.. but I will say I have no issues.. and it's been probably 35k..

It's weird that most don't have issues.. but some do.. almost like it's an on-off switch to whether you'll have problems or not.

I'm hoping I now have a 'good' transmission.. and won't have to worry about it.

i first noticed it around 12k, but I'm only having the problem when I downshift to 5th, anyone else experiencing this? no problems upshifting, just when I downshift from 6th.

Just took my car in for maintenance, I'll be getting a new transmission :)

I think mine is starting to get a little crunchy when I downshift from 6th to 5th, stupid Nissan tranny. I wonder how much money Nissan is losing due to these replacements.

how many miles are you at?

I have the exact same problem. I have to go from 6th to 5th VERY slow to not grind.
