CVT fluid change based on time #5407860 04/19/20 02:15 PM

Hi,

My mom's Nissan Versa 2014 only has about 5,000 miles on it, so she drives less than 1,000 miles per year all short trips. There are currently no issues. The Nissan manual have schedule for low miles car as an oil change every 6 months, brake fluid every 2 years, and coolant every 7 years. There is however nothing on transmission fluid other than have the dealer run something call Consult to determine the fluid deterioration rate is lower than 210000. There is no dipstick for the fluid so I can't check what color it is.

The problem is that when I contacted the dealer, they seems not to know what deterioration rate means and suggest that it should be changed since it's over 5 years. I am not sure how much to trust the dealer (or most dealer in general). I did tried to call Nissan USA but they just defer to their local dealer. Changing CVT fluid is not cheap and even on a severe schedule, the service schedule is every 30,000 miles (normal is 60,000 miles). At this rate, it would take several decades to reach.

What are your expert's opinion on this? From my point of view
For:
* CVT is not like motor oil. it's not expose to constant heat and combustion. There shouldn't be stuff like carbon build up.
* Transmission fluid deteriorate due to heat. Short driving distance means the transmission never heated up.

Against
* The fluid is factory original and may contains break-in metal bits?
* Fluid may still break down over time, it's been like 6 years.

The dealer being dealt with has since closed. I am thinking of trying again with another dealer in her area.
* Anyone know anything about this Nissan Consult III that they refer to in the manual or how much it would cost to have them run it?
* There appears to be an application call CVTZ50 that connects to a ELM327 OBD2 dongle to read the value. Anyone have experience with the app?
* How reliable is this deterioration rate? I think it's suppose to be calculated based on temperature rather than actual fluid state.

Paul

How long will your mom keep the car? Will anyone you care about inherit it?

I wouldn't change it. There is little concern for heat damage or chemical degradation. I would only worry about break-in debris, and I still think it's too early for that.

I would try a few other dealers. I am pretty sure you could tell a difference between getting a scripted answer or a technician who seems knowledgeable. Hopefully, one of your calls would score you a knowledgable tech or manager. If not, try an independent garage. See if anyone would recommend one that would be knowledgeable about Nissans. If non can be found, I would stick by the owners manual. I think it is safe to let go for the time being.

If ever there was a candidate for an electric car.

Are you at all hands-on?

Unless she crashes her car, for her entire life I expect. At the rate she drives, she would reach 35,000 miles in 30 years. I imagine the car would then be donated or end up being inherited by one of the grandkids. I do however want to avoid car problems since she will call me for help and I am on the other side of the country.

She is definitely a candidate for electric car, and I attempted to acquire one for her back in 2014, but unfortunately she lives in an older devlopment and there is no outlet for charging or at least none that won't blow the breakers when she charges.

I will try the other dealer and see if they are more helpful. It's not that I think all dealers are bad, but a lot of them no matter what brand of car appears to be either quote a rather aggressive maintenance schedule than the severe schedule in the manual or cite problems that doesn't exists. My wife's current Subaru dealer seems ok, the one where she got her car from not so much.

I have 2 Nissan's with CVT. The rate of driving your Mom's car is experiencing would make me suggest leaving it alone for another 4-5 years.

Your moms Nissan doesn't have a dipstick, but does have a fill tube. You could fabricate a dipstick to check the colour of the fluid. Get some picture hanging wire (braided stainless), about 30 inches should be enough, slide this down the fill tube (Nissan CVT have a locking tab on the fill tube cap - visit YouTube to find the simple method to pop it off) and get a sample from the transmission. Blot this sample on white paper towel and take a photo with your cell phone for future reference.

2-3 years forward, take another sample of the fluid and compare the colour to your 2020 Covid 19 file photo...this decides your next step.

I would not change it and I definitely woiuld not call another dealer for advice. There is no technician at a dealership that knows if it should be changed. It would just be an opinion. And given the low level of work going on a dealers now days, a good chance they will tell you it needs changing, just to boost their business. That fluid will be fine for a long, long time.

Can't even remember the thread, but I got it locked for throwing in the word that must not be mentioned in the same way you did, just being snarky. Had no intent of seeing it locked and other than that one word, my comment or the rest of the thread had nothing to do with it. We have some strange marshaling going on in this neck of the woods.

If I had to pay to have it changed, I'd leave it. If you can DIY, that's another story.

It's easy to do once you get access to charge pipe and get the stupid locking cap off. Access is a little tight on the Versa due to the tight engine bay.

Your well out of warranty based on time, so there's many aftermarket alternatives to NS3 fluid you can use.

That fluid should be good for a long time. I change mine based on mileage, not time.

If she keeps the car out of the salt, drives conservatively and has a local mechanic check on the car at least yearly I believe this car will last a long time. Ie, I would not Engels this time-based maintenance, such as fluids and belts. Her low cost for fuel should makeup for the cost of heeding these items, especially if she stays away fro, the dealer.

I would change out the CVT fluid with OE-fluid-only now and then likely never again, based on her expected mileage per year.
