Hi everybody,
I did some research on the net regarding Nissan Cvt fluids, but honestly, I couldn't find out what I wanted to know.... so I am trying here now with the hope to get some better results... WHAT ARE THE MAIN DIFFERENCE BETWEEN CVT FLUID NS2 & NS3?? and also TO WHICH VEHICLES ARE RESPECTIVELY INDICATED TO??
I would like to thank everyone who would like to share some info about it... thanks a lot

And thank you for your extensive contribution to this forum! You are permitted to do some research yourself, and to share what you learn. I am always blown away by the number of people who register to ask a question, and then can never be bothered to acknowledge or thank the person who actually helps out.
And, morevover, given the extensive history of threads here, by just using the search feature on this site, many will find that their questions have already been asked and answered.

You'll have to understand that most of the tech people here on the forum are not constantly always on the forum. We try to do the best we can. It may take several days to respond if it's not a dire emergency, just general info. There's no good reason for us to get chastised because of your impatience about something you can very easily find by doing searches.

For your information to answer your question about "WHAT ARE THE MAIN DIFFERENCE BETWEEN CVT FLUID NS2 & NS3?? and also TO WHICH VEHICLES ARE RESPECTIVELY INDICATED TO??", the differences between the NS2 and NS3 CVT fluids is viscosity and additives which appear to be proprietary. Referring to the Nissan Altima, NS2 is used in the 2007 - 2012 series, NS3 is used in the 2013 and newer series because the CVT was redesigned.

Rogo, do you have ... can you post ... the MSDSs for each here (NS2 and NS3). I had done an extensive MSDS comparison for all the major coolant providers several years back, and found that process most instructive. [One of the local (dealer) parts departments had a look-up on their system, which helped provide some of the information, though most of the data I compiled was not Nissan-specific; but, being a Nissan guy, I included theirs too.]

Thanks.

Hi! I was recommended for a transmission fluid fill at a Grease Monkey in Colorado and shortly after my transmission failed. I am no longer covered under my Nissan Warranty so I had to pay for the transmission replacement out of pocket. The mechanic that replaced my transmission believes that Grease Monkey used the wrong CVT fluid. We had the fluid tested at a lab and it only said that it was CVT, not ATF (no specifics on which type of CVT). I was wondering if you could tell me what the chemical compound is for the NS fluids? I tried to do a search but I am not finding anything that can be deemed super helpful. From your professional opinion, could using the wrong fluid cause transmission failure? Thank you for your time and help! I appreciate ANY information that you can share with me!

Using the wrong fluid can definitely cause transmission failure, in particular with CVTs because they require a unique transmission fluid with specialized frictional characteristics designed to ensure the belt or chain remains in contact with the pulleys without slipping. All manufacturers of CVT fluids seem to specify that the CVT fluids are a PROPRIETARY BLEND SYNTHETIC HYDROCARBONS AND ADDITIVES or a PROPRIETARY BLEND REFINED PETROLEUM HYDROCARBONS.

Hi iam using Nissan tiida 2011 model in Uae, recently I changed my gear oil with CVT NS2
instead of ATF oil. Is this ok or it will make any trouble in my gear box in future???
You'll have to determine what transmission is in your car. Is it a 4-speed AT or a CVT? If you use the wrong transmission fluid, the transmission is doomed to failure.

From what I understand you cannot swap the CVT fluids either way. The Nissan OEM NS-3 is a lower viscosity than NS-2. Using the wrong fluid can definitely cause transmission failure, in particular with CVTs because they require a unique transmission fluid with specialized frictional characteristics designed to ensure the belt or chain remains in contact with the pulleys without slipping. All manufacturers of CVT fluids seem to specify that the CVT fluids are a PROPRIETARY BLEND SYNTHETIC HYDROCARBONS AND ADDITIVES or a PROPRIETARY BLEND REFINED PETROLEUM HYDROCARBONS.

God, I love my ancient Tiida 1.8 CVT.
NS2 fluid all the way, and wouldn't take the chance of substituting or trying to go backwards/forward compatible.
It ain't broke, etc.
It's a rattly dented car, but is always serviced, and if it ever dies,(which, realistically it will), I'm gonna mount it on a plinth in my garden.
Just to sit back and remember the good times.

In 2020 I purchased a remanufactored CVT transmission for my '08 Maxima SE. They sent with the newly rebuilt transmission Nissan NS-3. The car's manual says Nissan NS-2 only and very black and white about it. . It's been 45,000 miles since, so I'm about to do a transmission service and I'll be using the NS-3 that they sent with the new transmission. That doesn't help you at all, but i wanted to share my experience, which is confusing to me, to say the least. I'll just put in what the experts did, for whatever reason.
