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.

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

      V37 Radiator removal

      By Duncan · Posted

      So, this shouldn't be such a mission, but there were a few tricks so I thought I'd post up a DIY for it. This was on a Q50 Red Sport but I doubt any other V37 model is very different (maybe just less steps for the intake heat exchanger hoses) I pulled the radiator out to flush it because the car was running hot at the track, but obviously the same steps apply for changing a radiator for any reason including an upgrade. If you are removing the radiator, you of course need to drain and refill, so have 5+ litres of blue coolant ready. You don't need to drain the intake heat exchanger to remove the radiator but depending on your plans you may need a couple of litres for that as well. You will also need something to deal with the auto transmission lines, I used 2x 8mm rubber caps on the radiator side, and a short length of 8mm pipe on the car side.....unless you can block these lines quickly you will loose AT fluid and it may be enough to hurt the transmission if you don't refill it. Other than that....lets go... "First, jack up your car". Yes really, and put it safely on stands. If you are not confident doing that you need to give this job to a mechanic

      If the forester is anything like our old 2007 GTB Liberty, I could near on run ling Long's and "rate them", as no matter what, it just hung to the road, even when abusing it in a hard launch in the wet, or throwing it at corners.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
