6th Gear grind

vipor · 09-24-2010, 04:56 PM

After the first dealership gave me the runaround I called the one I purchased my Z from and explained my problem, told them what happened, and expressed what I expected to happen. "I want to bring my car in, drop it off to have a new transmission installed under warranty, and be there less than 15 minutes. Please have a car waiting for me." They did exactly that, zero issues.

interesting...i get the grind and i don't even skip gears.

it usually happens on 3rd, and 5th. you guys suggest bringing it now or when it starts happening more often?

right now i say it happens 15-20% of the time. i thought i was shifting incorrectly but looks like i'm not.

Ive had problems shifting into 5th gear as well.

Demon Z · 11-15-2010, 05:01 PM

I've noticed this a bit myself. If I accelerate aggressively in first, second, and third, then skip to sixth, sometimes it doesn't want to go in. I can't help but think that maybe I don't have the clutch all the way in or something stupid like that and start second guessing myself, but I've been driving manuals for a long time, and I know when something's not right.

Just wanted to chime in as my Z has just recently started the 6th gear grind also. I expect no less than a new transmission under warranty when I go in. Hopefully that's the case.

can you update when you take it to the dealership?

i took mine today for another issue and i brought this up. they took a look at the transmission and they said it was fine.

for me it does not happen every day. like someone said above it almost feels like we are shifting incorrectly.

for the rest that got their transmission changed did they actually have you test drive the car with them?

Here you go-
5th gear "crunching" with shift

My sixth gear definitely grinds, and so does my fifth. However, my car is a 350 and has 80k miles on it. I've changed the clutch and the transmission fluid, and the problem is still there : / I can say that this is not a biproduct of my driving at least, because it's happened since I bought the car. Even the previous owner admitted to 'having his fun,' in it, so I'm assuming he was trying to act all pro in my baby.

LMBmikeZ · 12-27-2010, 03:52 PM

this makes me sick to think it is still happening to our Z's

!!! I had this problem with my 300zx and was also mentioned by almost everyone on the forums

I can honestly say though that my 40th Anni 370Z has not had any grinding in any gears!!!.... I can only hope next years driving season brings on no grinding!

dirTy_shoeZ · 01-02-2011, 11:46 AM

mine shifts like butter when your driving it hard and kinda clicks in driving slow. no grinds tho

BUMP for an update from VIPOR

Marcus Ryan · 01-03-2011, 01:44 PM

Not quite an update from vipor but I'm having precisely the same thing happen. 6th started grinding last week so I took it into the dealer I bought it from and they said that Nissan does not allow them to rebuild transmissions so if there's a problem they just replace it. In any case it's almost certainly the synchros. They didn't give me any trouble at all, told me to bring it in Tuesday and they'll put in the new transmission.

LMBmikeZ · 01-03-2011, 08:16 PM

damn!

I am not looking forward to this! I had the grind in my Z32, so I tried to use the redline MT90 switch for tranny oil. I noticed a difference

but it wasn't gone!

Now I have my fingers crossed hoping that my 370 doesn't get this problem........

09 370z Guy · 07-06-2011, 08:28 PM

I have the same issue with the 6th grinding. I am taking mine in next tuesday...I called and talked to the service manager at my nissan dealer and he stated he has not seen one come back yet, but has heard of this from other dealers. I fully expect what was already stated above, bad syncro = new transmission. Ill let ya know what happens...

symptoms - grinding when entering sixth gear from 5th gear.

butdamnbrian · 07-06-2011, 09:32 PM

i understand the synchros are different for 5 and 6 than they are for 1 2 and 3. anyone know more about this?
