Transmission failure

1slow370 · 10-12-2009, 12:36 PM

Well 6th is gone in my manual and the only thing i can think of is defective parts. Took it in showed the man in the uniform what was wrong and they are calling nissan to see what they want to do. Anybody have one replaced yet? Wondering if i'll be waiting a month for my car.

Well I hope you were nice to it and didn't abuse it. I would demand a loaner for the length of time you had no vehicle. Also your insurance might cover a loaner vehicle, I would check your policy.

This whole 6th gear issue is becoming more prevalent. I'm hoping I don't have this issue later one

Is there a trend yet we can piece together as far as more freeway driving vs. street driving, agressive vs. not, mileage, build dates, etc???

i had 6th gear grinding i have a new transmission on the way from nissan the tech drove it around for like 10 minutes came back and had one on order for me, should be here this week minimum downtime. im not to worried about the car, its a first year model there will be some kinks to work out especially with it being the first SRM transmission

1. How in the F**K do you abuse 6th with out going like 170?
2.9,600 miles
3. Transmission is ordered should be done next week.
4. Left the dealership got it up to 55 and after one shift the tech had me turn around and head back. Nissan approved replacement about an hour later.

iceman21_23 · 10-12-2009, 04:00 PM

heh i have just over 4k miles my self hopefully our new transmissions will last us a lot longer!

kenchan · 10-12-2009, 04:24 PM

1slow370- so it just grinds when you try to get into 6th?

is that how you started noticing the problem? wat where the early symptoms?

vifferman · 10-12-2009, 04:38 PM

Just curious...are all of you who have had the 6st gear problem driving the Sport Package with the syncro-match 6-speed? Or, does this problem also appear with the base 6-speed tranny?

No issues what so ever with my transmission.

A Transmission issue at 4 to 6 K points directly at driver attitude.

Good luck.

kenchan · 10-12-2009, 04:47 PM

vifferman -i dont think the gearbox itself are different between
SRM and non-SRM.. just a matter of having sensors on the gates to
detect shifter location of the gate telling ECU how much to rev vs
speed of the car.

in fact, if the problem is with the syncro's then SRM should
lessen the chance for the problem as it rev matches during
up-shifts too.

so not sure wat it is. it could be just a defective material on
the gear's collar??

.

Not necessarliy......While there are plenty of guys here who beat on their cars, there have been enough reports of this and similar issues with the 6th gear syncros to lead us to believe it is a relatively isolated manufacturing or bad part issue...

1slow370 · 10-13-2009, 03:52 AM

Attitude? reference earlier comment on how the F**K do you abuse 6th? hard downshift from reverse? Not my first stick and the first one I've ever had a problem with. When i said sixth gear is bad and showed the man he asked me if i track the car and i just said it's 6th his response "oh." It's already been approved by NISSAN.

Shifted hard into 6th every since i bought it like it took a little more effort than other gears until it dropped in. Start making the standard zipper sound, then progressed to Zipper + grind. If i double clutch and baby it(like 6 seconds to move in from 5) it shifts like the same old crap it was new but you could feel it was bouncing a bit. All in all totally unacceptable for a new car to have 6th gear or even 5th gear problems. The amount of torque those gears see doesn't amount to much that is why they are physically about half the size and beefyness of first gear(thinner and such). Also is why 1 and 2 get double cone syncro's and the rest are single. Chock this one up as one of the reasons to kick an engineer in the balls.

i'm shocked! '1slow370' sorry to hear, sux this happen on a new car! when was your built?

I dont have the 6sp but my 7sp runs perfect with zero problem!

kenchan · 10-13-2009, 08:20 AM

sw- your 7sp has a torque converter. There's your problem.

1Slow370z- thanks for the info. Most cars I've had were pretty stubborn to get into 6th when new, so I can understand why you didn't address it earlier to the dealer.

Keep us posted what the problem was.

So far my Z has been very smooth to get into all the gates. Was actually surprised how smooth it got into 6th.
