My New Gearbox

[Horsey]

I lurk here without posting much, but thought i'd let you know aout my experience.

6 weeks ago I got into my GT-R to drop my daughter to school and the engine and transmission lights came on and it only ha 1st, 3^rd and 5^th gears (how odd ).

After driving a few k's and stopping and re starting the car the gearbox worked properly again.

The car was nearly due for a service so I booked it into the dealer and asked them to look into the gearbox fault.

When I picked it up I was told they'd run a full check and reset everything.

It did the same the next day and was also in limp home mode, so was picked up by a truck and taken back to the dealer.

After downloading all the info from the gearbox/car etc to Nissan Aust (and onto Nissan Japan I was told), the dealer was instructed to do a few checks including draining the gearbox to see if anything other than oil came out, and with all this info the decision was made to fit a brand new gearbox.

It surprised me at the time that they didn't try changing electronic things like solenoids etc, or even opening up the gearbox to have a look, but I'm glad they didn't as I thing it would have just dragged on and on.

The gearbox arrived in a crate from Japan last Friday and was fitted this week, with me picking the car back up yesterday.

It is perfect again.

The only time on a track was about 2 hours in the wet at QR with the Dealer.

I've never launched the car.

Nissan Moorooka has been very professional the entire time, I was delivered a loan car when needed and was kept up to date with the progress constantly.

This has in no way lessened my love of the car; to me it is just one of those things.

But it is certainly reassuring that the dealer and Nissan Australia are so easy to deal with.

thats awesome.

my brother didnt have the same courtesy from blackburn nissan when he blew the gearbox on his 12 month old navara...

the dealership had changed hands so they said the warranty was no longer valid.... was quite an ordeal and took 3 months to finalise....

luv the pic of the gtr on the towie haha

The old tranny would have already been sent off to Japan for analysis if they didn't know what the problem was, maybe they knew where the issue was and knew that the fault was with the gearbox assembly and not with any electricals?

Now go put some milage on the car

Maybe one of the clutches shat itself, would explain you only having the gears selectable by the other clutch.

[Marlin]

^ Doubtful. More likely a failed solenoid. We struck a similar issue on Giant's.

AFAIK, Nissan OZ techs aren't qualified to pull the boxes apart, so a complete replacement is fitted and the originals go back to be remanufactured.

That would have to be my favourite part of this episode

You can't buy an Atom here and anyone would (with half a brain) realise that it's not quite as practical!!!!!

Talk to the guys who track their GT-R's a lot and see what problems they've had.

omg John here we go again....

1: You can buy the Atom here and you will soon be able to get it complied as well (but I will believe the compliance part once I see one complied, I know the guys trying to engineer it now, a lot of work, money and inspections have gone into it and they recon they are on the home stretch). Practicality doesn't matter, if it did then we'd all be in stationwagon hatchbacks.

2: You claim to have tracked your car for only 2 hours in the wet, yet YOUR car needed a new tranny shipped from Japan when your dashboard was flashing with warning faults. It isn't any good having a car that can do those times if you only have 1st, 3rd and 5th gear mate. If I had only tracked my cars for 2 hours in the wet, I sure as hell would be pissed off, I have no idea why you defend Nissan so much when from your first hand experience the car failed without even being driven hard.

The story is on this thread which was posted by Horsey.... look at post #3, that was me being encouraging a few days ago, wish I wasn't so nice now....

Also in regards to the times Nissan gives about the cars.... Nissan said the cars are capable of 3.2-3.3sec 0-100 times back in 2007/2008. I am yet to meet anybody in the whole country that has gotten anywhere near 3.2-3.3sec for a standard car..... this backs me up as well, it has been written by various R35 owners right here in Australia.

I have said it before and i'll say it again, I know almost all there is to know about these cars. I have driven them plenty of times and even came close to buying one for myself at the beginning of the year (it is in AE forums somewhere), if I thought they were that good I would have bought one already, it isn't asif they are exclusive or super expensive. Hopefully the MY11' model will finally be as good as Nissan hypes it up to be, but I highly doubt it as Nissan has Always exagerated with the R35.

PS: hope this tranny doesn't shit itself for you this time...

Mate I know what happened to your car

[g35me]

Sounds like his gearbox failure was an unfortunate one in a million scenario. I am sure every car out there has a proportion of one offs where an engine and gearbox has failed for no apparent reason. I drive mine every day and it kicks ass with no issues at all. All I see is alot of jealousy from people that spend 3 times as much on a car to get the same performance. And the servicing costs are not over the top at all. And you can't immediately void the warranty by turning the VDC off. And you can use launch control on the '10 models with VDC on so then you should get the claimed 3.5sec (Australian times) that Nissan have claimed. So much crap floats around on the internet from the uneducated.

All true.

The GR6 is a strong transmission, however it DOES have its problems. We make a living out of selling repair parts and designing fixes for them, so have a fair idea of what you can expect if and when something goes wrong. The OP in this thread is hardly Robinson Crusoe when it comes to having issues. Its not one in a million.

Common problems (when they occur) are -

Inadequate lubrication causing valve body contamination and subsequent P0731-P0732 limp mode

Piston seal failures, P0700 onwards codes and limp mode

Four gear synchromesh failure - the scrapnel causes missed shifting on fourth gear and P0731 and upwards codes

Line Pressure/Clutch Pressure sensor failure - P0830 (off the top of my head)

FWD Circlip Failure - catastrophic transmission failure or if you are lucky just a damaged main shaft

FWD transfer shaft Failure - P0700 and onwards.

Oil Pump Failure - Harsh grinding noise

Transmission case failure - as the name describes

We have repaired 2 x GTR transmissions locally in the past fortnight with a selection of these issues, and obviously shipped parts from Dubai through to Hungary (and most everywhere in between) to fix over a dozen in the same period.

The good news is that most of these problems can be avoided with preventative fixes

Hmmm, am I the only one confused about this particular post - it says the author is Horsey, but its just weird, sounds like someone else is posting it, like that other dude Kujotk is posting it - is this the same person?

So you are repairing the JDM's, cars without warranty?

I've taken this kid Kujotk's quotes from another website. He pretends he owns all these exotics and they're his dads.

At any opportunity he bags the shit out of GT-R's yet gets on here all nice and friendly!

He's a nasty little bit of gear really.

1: You can buy the Atom here

I smell a topgear challenge.

daily drive an Atom, and I mean pick up the kids , go grocery shopping and to top it off wear a suit + get a carwash .

JDM, ADM, EDM, SADM and USDM

(Lets not forget Gulf Spec as well)

Just a heads up, this is more than likely what the dealer was looking for in the oil -

Synchro pieces
