The early CVT's had only one drum in the fluid, which meant the higher drum wore quickly if the fluid was old or the fluid level was low. The newer CVT's, both drums are in the fluid, which makes them

Sorry to tell you, but the GT8 CVT box is widely considered one of the biggest ever mistakes by Nissan. Once you break it (which doesn't sound far off), there is NO-ONE that can fix it. Many cars have

Sure.. I was just referring to the V35 though.. the only V35 the CVT was available in was the 350GT sedan. Even then it was an option, the 5AT was also available.

I had my 2002 V35 cvt-8 gearbox serviced last week at Wairau Nissan on the North Shore. Was a few coins over $1000 for the service. Gearbox never had an issue prior with 135k on the clock so was more about giving it a longer lifespan. The fluid came out slightly dirty and the biggest thing I noticed after the service was it seemed to have more drive off the line.Particully notacable when sitting on a hill in gear I no longer need to have the brake on to hold the car from rolling back.

Did Nissan do the TCU (Transmission Control Module) fluid deteoration fluid sensor reset as well??

Did they replace the o-ring & filter also?

I've got the same model with 90,000kms now & CVT.CO.NZ aren't interested in sending me the tranny filter & o-ring seperately!!!

Any chance you can find out the cost to ship the KTF-1 oil from North Shore Nissan to Gordon, 2072, NSW via Sea Mail & not courier via you???

Im assuming they reset the tcu but after talking to the head mechanic the tcu doesnt accuratly monitor how hard the box has been driven. So you may have driven the hell out of your car for the last 40000k and the wear counter will only log that as a casual cruise.

can Nissan over there not do the transmission for you? it took some convincing for the dealer to even get nissan head office to send two bottles of KTF to do the service because of the price.

Why don't you go to Nissan and ask for the part numbers and then cross-check with the images on my for sale page?

CVT .co.nz sell the same package for Y34 and GT-8. I don't see why an RE0 gearbox would have two different shaped dumps between models.

I'm not going to do your homework for you.

Also if you want cheaper oil, do a search and find one of my posts from late last year for a link to a website. $800 for 12L delivered

I only found the web site global.rakuten.com.

Is that the one you were referring to Lee?

Hey felas.

I've been in talks with Gerrit from CVT.CO.NZ and he is suggesting I not buy the KTF-1 oil from Global.Rakuten Japanese web site because a couple have done so & now have stuffed transmissions!!! Is this the fact??? Or his just wishy washy talking me down from buying from Rakuten for cheaper & therefore him losing out???

He says if I don't have the TCU Reset, my car will start to limp after a short while because the oil contamination sensor counter has not been reset by doing the correct adaptation procedures.

Has anyone on here bought from Global Rakuten & used the KTF-1 without any hassles???

Here are the screen shots below;

He didn't say don't buy the KTF-1 from Jp- he just said make sure you buy the CORRECT oil, otherwise you will blow your CVT, which is true.

What about the adaptation procedure he is talking about?

That doesn't explain why I should or not follow his instructions.

There's an auto box on eBay for $550. Add shift kit, throw it in, laugh around town. Will save you the hassle of going through all this with a massive possible downside.

I'm sure the guy at nzcvt is heaps happy you posted for all to see that he is happy to commit a crime and under declare the value to avoid tax.

Auto won't simply bolt in though, not electrically.

You will need the Consult 3 unit to reset the oil contaminant counter.

Well Gerrit is suggesting I can do it all by myself.

So I've had enough guess work.

Will just take a gamble & get his $1,600 CVT kit & then see how it's meant to be done.

It seems only the Waikaru, NZ fela had Nissan GT-8 Extroid flushed & even then he reckons they didn't reset the TCU...

Pay $1600 for oil and can't afford $150 to get a Consult 3 clone to reset it properly? Ok...

My suggestion, sell the car and buy a manual V35, they are cheap these days.

I can't imagine the ECU jumping into 'limp' mode just because you don't reset the fluid det counter. Some have suggested there may be some changes in the way the TCU controls the transmission based on the fluid age. I haven't seen anything official to confirm this and I have my doubts this is any more than a plain old counter, but if it is true, it would be a good idea to reset the counter when you replace the fluid.

No idea if there is a 'non-consult3' way of doing this on the V35. I know for sure it is a consult only procedure on the maxima CVT TCU..

this what I have said to others.

But even if it did, I would much prefer the peace of mind knowing the oil is changed.

As far as the Y34 goes, there is a km's counter menu in the navigation system used to monitoring service intervals. It can be reset with a few buttons. Have no confirmation that it would actually affect the TCU though.

      R34 Handbrake light saying ON and intermittently flashing

      This. The R34 handbrake icon DOES come up when the brake fluid level is low. You might be sitting right on that threshhold. I have been down this diagnosis path and this was the solution (and it was pretty much as full as your picture is to begin with).

      Unfortunately the cavaet to that is that while any scan tool should be able to read the code, the workshop will need a consult plug to OBD socket adapter. You don't have a location on your profile, where are you based?

      RB25DE NEO with Haltech ECU

      By Kinkstaah · Posted

      @Haggerty this is your red flag. In MAP based ECU's the Manifold pressure X RPM calculation is how the engine knows it is actually...running/going through ANY load. You are confusing the term 'base map' with your base VE/Fuel table. When most people say 'base map' they mean the stock entire tune shipped with the ECU, hopefully aimed at a specific car/setup to use as a base for beginning to tune your specific car. Haltech has a lot of documentation (or at least they used to, I expect it to be better now). Read it voraciously.

      I saw you mention this earlier and it raised a red flag, but I couldn't believe it was real. Yes, the vacuum signal should vary. It is the one and only load signal from the engine to the ECU, and it MUST vary. It is either not connected or is badly f**ked up in some way.

      @Haggerty you still haven't answered my question.  Many things you are saying do not make sense for someone who can tune, yet I would not expect someone who cannot tune to be playing with the things in the ECU that you are.  This process would be a lot quicker to figure out if we can remove user error from the equation.
