Hey what's up all, I got an issue with my 2003 350gt-8 and I'm hopeing someone maybe able to help me with it or point me in the right direction.

So here it is...

When I start my car (especially in the morning) it runs extremely sluggish (kinda feels like the breaks aren't releasing properly).

I can put my foot to the floor and it won't jump past bout 2000rpm. I can feel the rear axle shaking as it struggles to take off but the car just crawls.

Eventually after stoping and starting my car a rediculous amount of times it will come good. You can feel it return to normal performance (feels like something releasing and the car performs like normal). Now initially it only happened occasionally and would be fine after stopping and re-starting the car once, but now it takes 10 - 15 minutes of stoping and restarting before it finally cames back to life. I believe it went into fail safe mode for a while but a consult scan proved me wrong.

Here's what I have done:

Had the front rotors/pads replaced and the rear ones thouroughly chedcked.

I went to nissan and talked them into a consult scan which revealed no engine error codes. They also scanned the transmission which revealed a code simply saying "cvt function". I wouldn't know where to start in tracking down what that means (for the record the gt-8 has a 8speed Toroidal CVT).

Initially I suspected the breaks but after a bit of testing it doesn't seem to be. I was thinking it could be a faulty/caroded sensor in the transmission maybe, hmm I don't know.

So I basically can't drive it until I get this problem fixed and so I'm stuck driving my girlfriends lemon jeep

So if anyone has any ideas what so ever please let me know or if you know anyone that may be able to help I will be eternally greatful...I miss my machine...

If you need anymore info just let me know!

Thanks for taking the time people!

Sorry to hear you are having problems. I thought it could it be an ABS or brake initialisation problem, or the foot/parking brake may be stuck or damaged? Usually when I roll off in the morning, the brakes make a small noise, like they are being tested or initialised. This only happens once after starting and crossing 10-15kph.

Will the engine rev out in neutral?

What about the VDC (traction control)

Hope it gets sorted out soon.

Btw, I saw a black 350GT8 on mountain st broadway about a week or so ago, and nearly jumped out of my seat. was it you?

Sounds like the car is going into "limp mode"

If the ECU detects some kind of weird reading from one of the many sensors it will put the car in a fail safe mode so you cannot do any damage (should something be wrong). With limp mode, once the ECU detects that everything is normal, it will bring the car back to normal operation.

So my guess, is that some part of the start up process is sending a faulty signal to your ECU.

Best bet is to take it someone who can get the fault codes from your ECU and you should be able to pin point where the fault is coming from.

Hey guys thanks for the responses

I've had the abs and asll the brakeing system checked with no luck. I thought it may have something to do with that initial break noise but the manual that came with the car said it is perfectly normal to hear. The engine does rev out in neutral it's only when the car is in drive or reverse.

I've tried switching off the vdc with no luck there either, doesn't seem to make any difference.

Where's broadway, is that in sydney mate?, I'm in queensland. There's not many back gt-8s around, I think if I ever passed one I would jump out of my seat (as would the other black gt-8 driver. They all seem to ber 2002 models, is yours 2002 or 2003?

Nismo, I too was so damn sure it was fail safe also... everything seemed to point to it. So I took it down to nissan and got a consult scan after a bit of sweet talking. The scan revealed no fault codes but did reveal (what the mechanic believed) a fault code from the transmission that simply said

"cvt function". That's why I'm thinking transmission but every other guess (like the breakes/fail safe have been wrong), though I guess its trial and error. So if I wanted to get it checked would I take it to a transmission place or an auto elec?

Thanks for taking the time fellas!

The problem with transmission places is how many have experience with CVT's?

Maybe see if the Nissan guys can take a better look. Both the current Maxima and Murano have CVT transmission, and although I'm sure there might be some differences there may also be some similarities.

Did they offer to do anything further?

Also try searching google for Maxima and Murano forums. See if you can find similar stories. Both these sell in pretty high numbers OS and I know there are dedicated forums for both cars. I think the maxima one is www.maxima.org

Hey,

I know that this is a really old thread, but I was wondering if anyone could tell me if kleenbeats fixed the problem he was having with his car?

I have attempted to PM but it appears that he no longers comes onto the forums.

I am currently having this same issue with my car and the same error code, but nobody seems to know what exactly is causing it. I spoke with CVT in NZ but they have said that it is because my car needs a tranny service. Problem with that, this has already been done and with the correct fluid before anybody rattles on about this. The fluid and instructions were provided by Nuwan at Import Revolution.

I have searched the forums but have not been able to find a thread detailing how he fixed the issue.

I know a few people have given up on the GT8s and parted the car out, as it costs more than the car is worth for a new CVT transmission.

I have heard of some putting a coupe auto trans in (which is a pretty major job including ECU change), but have also seen some parted out and sold off in bits.

I have been warning people off of the GT8s since Adam was a boy, but some learn the hard way :(

      RB20DE NEO smallbox clutch.

      By Duncan · Posted

      yeah first and reverse is where you will find clutch release issues (whether hydraulic or mechanical) because the difference in revs required is the highest there; particularly changing down from 2nd to 1st when still moving. To be clearer though, it is possible that the clutch release bearing is the wrong height. This is less likely than a hydraulic issue but it is not unheard of when you are mixing and matching

      Replacing turbo water line - any recommendations or advice?

      By jtha7 · Posted

      Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!

      RB20DE NEO smallbox clutch.

      By MBS206 · Posted

      From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.

      That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.
