Transmission problem?

[babibengkak]

Hi, sorry if this has been asked before, but i've searched the forum and couldn't find anything about this.

Has anyone heard about a transmission problem that occurs even when the car is left bone stock?

Just got mine delivered last week, and the transmission does sound a little loud, especially at low speeds. (sometimes when i switch on the engine it makes a really specific "metal crunching" sound, it seems to come from the rear, but i'm not 100% certain. Could also be the starter motor)
Some dealers here claims that they heard from Nissan Japan that early production cars may have problems.
(or maybe they are jealous because they couldn't get their ordered cars shipped in)

Also, can you guys help me out on installing a turbo timer?
Since it doesn't have an ignition switch, should i just connect the cables which normally go to the switch on to the starter button?

Thanks.

To offer some advice on a turbo timer, I will need to try and find a wiring diagram. What you need to have happen is the ignition 12v key on keep power while the 12v acc wire does not(for 90% of vehicles, the GTR may require that to have power as well). On a toyota, even though it has a smart key style, it still had a "traditional" style ignition wire plug. I'll check Monday to see if we can find a OEM wiring diagram anywhere..

No tranmission problems reported, yet.
that is the car, the GT-R is loud! pretty loud, alot of moving peices.

as for the Turbo Timer, what brand/model do you have right now?

[babibengkak]

I'm currently using a Pivot Baby Turbo Timer on my Evo ix. I like it because it has the auto function which determines how long the engine stays on, depending how you drive the car. I've been using this since 3 years (back from evo viii days). I was really amazed that with only 3 wires it can manage that. (other turbo timers have it as well, but this one is only around $65. where as the Apex'i turbo timer cost almost double)

I still haven't installed a turbo timer yet on the GTR. I really want to make sure that everything would work out, since there is no technical assistance whatsoever here where i live.
Due to the fact that i'm totally lame in electrical things, i really need you guys help on this.

The GTR is not loud actually. It sounds a bit like a 600cc motor bike from the inside actually.
At low speed city driving it shifts way too often, but that's about the only thing i would criticize about the car. Then again, we could always shift to manual mode.

[Ev0H8t3r]

Ok I'll try to do some research if anyone in japan as instrcutins for the TT for the GT-R....BTW where in Asia are you? if i had to guess by your screen name, Thailand...just a guess...

[Phoenix]

I have 4 - 5 minutes of non-boost driving to get to my house after arriving in the subdivision where I live; it would seem that would be enough to cool down the turbo.

Honestly, I generally run an ancillary fan switch (i.e. a/c fan) to the interior near the trunk pull. I generally try to leave it on at all times. The engine usually sits around 165 - 170 unless I am at the track. The point is it helps cool and create air flow around the turbo housing as well.

I think the easiest way to avoid boiling the turbo is to refrain from boost applications as you appraoch your destination so it has time to cool. If this is not possible, open the hood.

Evohater, I'm in Indonesia.....my nickname means swollen pig...(babi=pig, bengkak is swollen)....it's Bahasa Indonesia.

just out of curiosity, do you really hate evos? I like them a lot....for a daily driving i would still prefer the evo to the gtr (for practicality), seating position, and for me, since i'm small (not really pig sized) the evo recaro seats hugs me better.

I just found out that the GTR comes delivered with Gracenote......it records all the cd you put in to it just like a bulit in i-tunes software. So i don't know if the USDM model comes with this, but if it does why bother adding the i-pod interface option?
It also comes with a Compact Flash card slot. The HDD is 30GB if i'm not mistaken....i have to read the manual again....(with the help of a japanese dictionary). So you could easily transfer your MP3s from your itunes library into the car.....

I was amazed by that today....HDD recording is common, but a stock car supplied with a HDD with Gracenote....they really put details into this....

[Ev0H8t3r]

Aww Indonesia.....Well, that would have been my 2nd or 3rd guess...I grew up in Asia most of my life so I know a few phrases and words around Asia :)

LOL No I do not hate Evos, I just stuck with my original Screen Name from when I owned my STi, and since Subaru and Mitsubishi are rivals it was a good name ;) I loved my STi, great car and Evo' are great cars as well!

As for the iPod interface option, you are right...I was wondering why as well, but alot of people will do this... -They will hook up some AV unit so they can play iPod videos on to their screen...I was thinking of doing the same...still up in the air...heck the GT-R holds/stores/records like over 2,400 songs...But, again for when it's time to resell (if you ever decide to) your GT-R the more options the better IMO...

I think the 1st day I would be out in the parking lot loading up all my CD's into the car, just like when I got my 1st iPod...LOL!

did you get the iPod interface with your GT-R?

According to Endless Racing, clutch problems occur at 1.1bar of boost:

Here is something interesting... Transmission or clutch might be GT-R's weakest point.

MCR have been giving their Nissan GT-R full load of work since day one. The MCR GT-R is making significantly much more power than non-modified GT-R and has been hitting on tracks constantly.

It seems like the extra power in MCR's GT-R is having some issues with their tranmssion. They said the gearbox is wearing out much quicker under the stress. Seems like DSG might be the culprit, but they won't known until they taken apart the transmission.

[babibengkak]

Hi again guys.

The GTR is competing in the Japanese touring car championship right?

What clutch and transmission are the NISMO GTR - GT 500 using?

[Ev0H8t3r]

damn good question Andrew! that has not even crossed my mind!
I am sure Calsonic or NISMO has something out there...
Give it a few more months!! By the time most of us are ready to do some major work on the GT-R everything should be cleared up by then!

[JeremyBlackwell]

If I'm not mistaken, that car actually has a V8 naturally aspirated with a different transmission. Can any one clarify?

[babibengkak]

The NISMO GTR uses a VK 45 engine.

But wouldn't the transmission layout be the same if they utilize the same chassis?

[RRnold]

Didn't the same hold true for the SR20DETT motors?!? :confused:

[ATLsupra]

Transmission on the GT500 are not the same as in the retail GT-R

hi babibengkak, i have the same problem with my gtr too, saya tinggal di indonesia juga, bisa saya minta no telp mr.babibengkak untuk discussion?? no hp saya 0811136242, thanks

[Ev0H8t3r]

Carbon next time put your Telphone number in A PM so you dont get any weirdo calling you!

[samurai_sony]

that sucks. Same with the auto TT supras. Cant hold much more than 600hp. Maybe nissan will consider a manual tranny later on.

[Panbkk]

Just to make a point. I was told that there are two axles, one going to the back and another run from the back to fraont. it is the GTR character not a fault.

[JeremyBlackwell]

Actually the GT-R transmission is a manual type transmission, it just doesn't have a conventional shifter. It is a similar type of transmission as the F1 that Ferrari offers. It does not have a torque converter and isn't hydraulically operated like a true automatic transmission. I like to refer to it as an 'automated manual' transmission :)

[samurai_sony]

You are correct. I just think there has to be something to make it hold more power. I am certain Nissan has something in the works for more power.

[DarinF]

To answer your original question, those noises are NORMAL. The service manager who was the only one allowed to drive my new GT-R from the back to the front to deliver explained the noises and said they are NORMAL.

My Gallardo makes various clicks and clonks when engaging gears and the GT-R is no different, just not as loud.

As for your shift patterns, that's in normal auto. Its always trying to get better gas mileage so you end up in 5-6th gear pretty fast no matter how slow you are driving around town. I LOVE manually shifting because I like being at a higher rpm so when I lay the smack down the car gets on!

The closest I can compare the NORMAL sound of the car to is on start up it sounds like something is loose in the engine and there is no oil.. again this is normal :P and when engaging gears the clutch seems to engage after you press the gas pedal.. where other cars I've driven will lurch immediately, the GT-R does not.

Hope this helps your worries :)

[Romper]

When my buddy picked up his GTR two weeks ago, the dealer had him sign a release form which stated he was told about the expected engine and transmission noise.

He said he does notice the occasional sounds, but its no different than his F430 or Gallardo. For those of us that have tracked stripped down bad a#@ cars, we know these internal sounds come with the territory.

When I get my GTR, I'll plan on disguising my background noise with a kickin' stereo system.

[mmc2488]

When my car was delivered, I was told that one of the keys was not programed to work with the car. This sent a shockwave through Nissan North America. They were so intent on client satisfaction, they sent a high level tech from Japan to figure it out. I was able to get some info from this "Iggysan". As they call him. Transmission clunks and grinds are normal as long as you havn't done more than 5 or 6 Launch Controls. A guy in New Hampshire blew his trans after 20 or more with 2500 miles on the car. If you are a new r 35 owner, you know that anything that happens when TC is off is not covered under warrenty. That will suck for him. But more to the point. I own a R 35 and a f430. They both make very similar sounds on start up and while running. And the 430 is a single clutch.

Interesting. I wonder what the first upgrade for the transmission/clutch packs will be? ;)

[mmc2488]

After your first 1000 miles, you are able to have the tech adjust any problems with upshifts and down shifts. I have noticed that 2nd to 1st is unusually abrupt unless I get it perfectly. I try to down shift right around 20 mph in order to get a good blip 2nd to 1st. doesn't always go that well. Sometimes get severe engine breaking, making it look to other people that I have botched the down shift. I brought it up to my dealer, and they will try to adjust the trans at the 1K service.

I've noticed the same thing on downshifts in lower gears...

[mmc2488]

Have you had any spills at the pump? Was told that hot weather could cause a back flow after the shut off. I have had it happen twice. Now try to fill at about 1/3 the speed. Seems to work.

Hey bud, I just replied to your other thread about this topic. See ya

[babibengkak]

Hi Jeremy,

i'm still holding back on modifying the GTR because of the max. load limitation on the tranny/clutch. Are there already upgrades available?

Not yet...

[mindlessoath]

Just in. alot of trans issues are being had all around. its not just the clutches. so more work than just clutches need to be done. Just wanted to say that without going into details. if you add more power its going to wear the clutches faster, but thats the least of the problems.

a stock R35 can also have these problems too. limit the amount of launch controls and you will be better off, thats for sure... and always change the trans fluid and keep temps low.

[Norman]

yes

[Norman]

:confused:Is the transmission any different with early 2008 JDM and USspec, I had heard Nissan have improve that!==

[mindlessoath]

there is slight changes, yes, but as far as i know only differnt by the computer. internals i belive are the same or very simular. even so these problems were seen with the usdm press cars aswell.

[Norman]

tks.heard that "romours" the engine / trans mounting(rubber) and the sus had improve the stiffness for US/late2008JDM too...it can handle more torque without twice the trans.that's why it can handdle more torque near 90kgm..,my "old" model can up to 80kgm only.:(

[DarinF]

Im sure there will be a nice $5k kit to upgrade the trans to a monstor trans soon :) > hint hint Jeremy <

Those parts are in development and may be offered. Understand solid mounts are for race cars, and will create SUBSTANTIAL noise in cab.

[nuanpi1]

Hey i am having problems going from second to first gear it slows down and then it sounds and moves forward in an aggressive manner. Has anyone have this problem?

[Norman]

yes,me too,looks like there is a stupid driver in a car^^,especially in the morning when the engine is not warm enough...but the sound from transmission is normal at R35.you can try to adjust it from Nissan service center.

[bs63366]

I heard that the trans are getting killed from taking the TCS off and doing launches. This is with a stock R35. Also like was said before this is not warrantied by Nissan, even if you only do it once.

[Norman]

My GTR haven't try launch control yet^^, about 2000km now.but i will still try it about 3000km for once,one only^^

[johnnyplatnum]

I'm coming from a modified Audi S4 so am used to noise issues with these type components.

I was presented papers to sign regarding engine/transaxle noise, increased service needs and expense and need for dealer explaination of operation of performance controls. This is fine though the way it was given to me after I had signed the sales contract and made the deposit was not entirely an honest business practiced as this should be brought up before the customer has legally commited to the car.

[wccl]

Happened to me twice

[CajunGodzilla]

Happened to me twice also when I first had the car. I simply slow the fill rate now after the tank is 80 to 90% full. No more issues.

[Norman]

Any update for the timer? can you put the step by step on the installation forum. thanks

To offer some advice on a turbo timer, I will need to try and find a wiring diagram. What you need to have happen is the ignition 12v key on keep power while the 12v acc wire does not(for 90% of vehicles, the GTR may require that to have power as well).

OK!;) thanks

[JaredPink]

Looking into the diagrams and still working on it. I have some testing to do, the smart key makes for some interesting factors in keeping the car running, arming the alarm, yet allowing the idle down. I do have some mad scribbles though!

And for future timer talk, lets move it to a independent thread so we can keep this one on topic!

[Norman]

Em... especially the alarm...wow,seems lots to solve:p
keep on it:D
thanks

Mine does this or will not downshift from 2->1; i asked the dealer to adjust at the 1k service- still the same

Hey Friend!
Change your trans oil immediately!urgent! by OUR experienceSSSed that's the symbol/signal(how to called this?symtom???) before GR6's valvebody JAM!!!:eek:
i just think to write a post to everyone to careful about this! seems not necessary now.

[babibengkak]

Hi again.

So now my trans oil temperature is at 93 C
It used to be operating at around 83 C.
I have 9K on my car. I still couldn't get any transmission oil here so i've stopped using the car since 3 weeks.
Would it still be ok to drive it since I've don't have the above mentioned "symptoms" ?

[Norman]

93c is a in between the "very" safe value. just a slightly different driving style can raise the oil temp from 83c to 93c. seems your driving is more aggressive now:D

BUT! have you ever change the trans oil? what milege now? any shift problem?
and if we(SEAsia) didn't do any "gear learning"(clutch adjustment) by consult-3 may cause more transmission problem too,when further and further clutch engage gap causing more debris,oil pressure drop drop drop by more gaps and jerks.....
it may have higher temp cause by metal debris and friction too.

the first after run-in oil change is very important especially for us (we had no "gear learing" by each time factory service,we do our own:( ,somebody'S' think that's the new program do the better engage...actually most from the factory every service FOC clutch "learning":))

you can change the trans oil temp according the factory service manual when below 110c ( i recommend 10k to 15k km ).

[babibengkak]

Hi Norman.

thanks for the info.

I'm not driving harder, even at lower speeds the tranny temp is higher than before. This started happening about 2 months ago. I've haven't changed the transmission oil yet, still waiting for shipment from nissan japan.

Not at all:)

you can get Pentosin-2 at a Audi or Volkswagen service center or BMW M3's Pentosin-4.Both work very good in our GR6. Even the Mecedes Mclaren SLR using Pentosin! And i guess that's the easiest way for you.And many of us in Asia using Pentosin with no problem at all.
BTW Pen-2 thicker than Pen-4.;)

[Jon]

If all else fails give us a call... there are very few trans issues we havent been able to fix these days... PM me with the current condition of the trans and any error codes still in the system if it is still not working right.

[drwho?]

My transmission light just came off yesterday, at 4000 miles, just parking the car after a 1 mile drive without ANY sport driving.
the trans light flashed, the warning light came up, and the message board saying "M/T system faillure, drive to your dealer". This happen when I putted the car in park.
NEVER launched the car with LC, but sport driving often.

When driving to dealership, the car had no power, the car was in automatic mode, and was shifting only in 1st gear, 3rd gear and 5th gear.

No bad mecanical noise, no strange clutching from the computer.

When i arrived to the dealer, I turned it OFF, they back on after 5 min. The trans light was OFF, but the check engine/inspection light was on, and the warning was not gone.

The Dealer in Silicon valley will look at it monday, I ll keep you posted.

Francois

[Norman]

Oh, you still have 1st~6th gear when in limp mode?

[drwho?]

Update 1: Nissan is saying that the 2nd gear issued a Diag warning, Nissan GTR hotline got the code and is deciding what to do.

I will get more info tonight.

[Norman]

oh... guess remove/clean and install only...
