Hi everyone

My 350GT-8 cvt has a problem in gear shifting. This appears when I drive it for 40-50km. Once the problem start it will reduce the gears by itself and stay at 1st gear. When you keep the car switch off for couple of minutes and turn it back on it will drive for some time without any problem.

It has done 65000kms all together. Any helpful opinion would be highly appreciated.

Probably a sensor fault.. you will likely need someone with a consult2 to figure out what is happening. They can be expensive to fix, and a lot of people have written off the car when they have had problems with this particular CVT.

Please, PLEASE use the search function before starting a new thread - this has been covered DOZENS of times before. And as Sonicii said (and from my own experience) you have basically bought a lemon, and it is more than likely unfixable. These are VERY unreliable gearboxes, VERY expensive to troubleshoot and almost no-one in Australia has the expertise to fix them.

don't know if I would say they are particularly 'unreliable'. the problem comes when something goes wrong.. you struggle to find someone even willing to look at it.. then struggle to pay the repair bill when you do.

Hi mate, do you no anyone who can scan it and find the problem. I have been to few guys and with their tools they couldn't. If u know someone in Melbourne please let me know.

Thankz

Sorry, I don't know anyone in Melbourne. If you have any decent Nissan dealers, they should be able to check it for you.. otherwise, it might need someone with a consult2/3 clone. I don't think the basic OBD2 tools will access the TCM.

How long have you had the car and how many kms have you done? Do you know the gear oil has ever been replaced? (Just curious) im doing a full flush next week, sump will come off so will have a quick look for any sensors

It is with me for nearly 3 years and I have done about 20000 kms. Just want to let you know one mechanic told me cvs shouldn't be flushed but I don't know it is for a fact.

people have different theories on fiddly gearboxes in a "if it aint broke dont fix/maintain it" sort of attitude. Personally, I think being proactive is a better way to go.

I've just imported my car with 100,000kms and the day after it gets rego'd im doing a full flush on the CVT.

My car is fixed. It was a speed sensor fault. Guy who repaired it was an expert in these cars and if you r in Melbourne and wanting a good machanic contact him. Thanks everyone for their comments.

I have just finished conversion of my gt-8 to 6sp M/T. The only exsisting issue is to customise centre console which i have decided to buy an E-stopp parkbrake system which really is just providing hole for switch......I strongly believe that it is cost feasible to do conversion. Cvt oil is roughly just under $1000 every service interval of 20000km. A conversion kit is around $2000. If you are mechanically knowledged you shall find conversion of a medium factor. What a lot dont add to cost saving is that once M/T is installed you now have your vehicle tare weight under 1500kg ( with cvt = 1550KG). This in New South Wales equates to a yearly registration saving of around $140. I WAS A MECHANIC BACK IN 94' HOWEVER REALLY WOULD HAVE LIKED FOR A SHOP TO CONVERT FOR THE SIMPLICITY OF HAVING A HOIST. I WENT TO 40 DIFFERENT SHOPS AND ALL SAID NO EVEN THOUGH I WROTE STEP TO STEP INSTRUCTIONS. MODERN MECHANICS TODAY JUST WANT TO SERVICE, REALLY ARE YOU SURE YOU ARE MECHANIC!!!!!!!!!!!! FOR THOSE OUT THEIR CONSIDERING CONVERSION I AM HAPPY TO PROVIDE HELP WITH ANY KNOWLEDGE NEEDED DURING CONVERSION.....ADAM---0435729442....SYDNEY :yes:

Glad it's sorted, thanks for sharing

Also Nissan factory service manual says cvt oil to be changed every 100,000kms. I don't know why you would think 20,000kms is acceptable for an oem box

    • What an awesome idea to fit the facelift Lamborghini Diablo headlights. They are a perfect fit!
    • An update regarding the registration with the DVLA I sent off the paperwork the day after I collected the car from the port, two weeks later it was all returned with a letter explaining they have rejected the application. This was because the cheque was £20 short for the road tax (I used a price list I found online). Nevermind it is what it is, it was sent back to them the following day with a new cheque. Fast forward another 2 weeks or so, I called them for an update to be told it had been rejected. Yesterday (16th September) I received the documents back along with another letter, this time it was because I didn't put an X in one box on the V750 (personalised number plate certificate), which declared that I had the rights to the personalised number plate. Why this wasn't mentioned in the first rejection letter, I don't know, but it could have saved this headache. The documents were sent back today, so fingers crossed third times a charm and it'll FINALLY be registered on the road just in time for the bad weather (woohoo!) To cheer myself up I lowered the front 25mm, was sick of seeing it sit like a monster truck. No idea how much clearance I'll have getting on and off the driveway, I'll worry about that when I can actually drive it
    • You're going to miss not worrying about rust in the strut towers like the Skyline shitboxes out there
    • A few little updates that weren't filmed due to not taking long to do or not interesting enough for their own video. My new K&N Air Filter arrived, I went with an RU-4180 which matched the dimensions of the universal cone filter the car originally had.  The battery had gone flat, while that was charging I tidied up the spaghetti wiring at the bulk head and down the sides of the engine Next job was to swap the stereo The Kenwood harness had the female ISO plugs cut off and the male ISO plugs cut off the adaptor loom and joined with bullet connectors. I ordered in a repair loom through work and re-did it all. New Kenwood unit installed (Android Auto, DAB, Bluetooth, Reverse Camera) The bonnet/hood gas struts have been poor since collecting the car. I couldn't find any suitable replacements locally so took a chance on a pair from AliExpress.  The originals don't use a retaining clip to secure the cup onto the ball fixture, would explain why I struggled for 10-15mins trying to pry off the cups. The ball fixtures unscrew using a 12mm spanner, new ones are the same size. Sadly no photo of them fitted, you're not missing much lol The dished Momo steering wheel got replaced with my Momo Tuner, turns out I ordered counter sunk bolts for the horn trim ring (like they normally are for the steering wheel) instead of allen cap (flat seat)  A terrible photo of a Quaife style gear shift knob I've had stashed in my tool box for many years after purchasing the incorrect thread size (I can see a pattern emerging with ordering incorrect parts...) Also threw in a cup holder and a (empty) Boss Coffee can, because why not  
    • GT-R clearly the better choice! The 300 is certainly not insaly fast but has a decent amount of poke. Does a nice little drift around the corners with a decent amount of throttle. It's VERY predictable in a slide too.  Feels so progressive! People probably presume there's a 25 year old driving it based on my behaviour this week! 🤣
