Mechanic Topped Off CVT with Regular Transmission Fluid

I had my front axles replaced on my 2003 Murano (145,000 miles), and I noticed that my mechanic topped off the transmission fluid (due to fluid loss during axle change) with regular transmission fluid (not CVT fluid). He probably added close to 1 quart of fluid. Does anything need to be done to address this? If so, should my mechanic be responsible for the cost? Thanks.

The only fluid approved for the CVT is Nissan's NS-2.

The CVT holds 10-3/4 quarts of CVT fluid. Your mechanic adding one quart of conventional fluid should not immediately harm the CVT because the existing 9-3/4 quarts may have sufficiently diluted it.

However, I would definitely bring it to your mechanics attention and request that he do a flush and fill. A flush/fill will require approximately 12-14 quarts of Nissan NS-2 fluid.

And yes, the mechanic should cover the full cost of correcting his error.

Hi Njjoe - I plan on refilling my transmission fluid only when there is a leak or it is low, I will never flush it to avoid problems, so when refilling can it need up to a litre of Nissan Ns-2 to refilll at any given time? Thanks.

That is an impossible question to answer.

If a seal fails then you may need several liters depending on the severity of the leak and the time elapsed between inspections.

However, if the seals remain fine then you may never need to replenish the fluid.

Let's hope for the latter.

I would NOT drive that car until the fluid is flushed and replaced. I would be reluctant to drive as far as the dealership, but I would do so gently. That's the ONLY place I would drive it!!!!

Since you are beyond the CVT extended warranty coverage, you can do whatever you want on your cvt. You can use any type of fluid you like beside the NS2. But you let us know what happens, if any, since its only the NS2 you should be putting in there according to nissan.

If you plan on driving/keeping your MO for a long time, I would insist in the full fluid replacement---12 quarts. I would not risk the 6k dollar cvt replacement because some mechanic put in the wrong fluid. Would you? It cost me about $140 for 12 quarts of NS2 fluid--ebay--when I flushed my cvt fluid several months ago--80k.

why did you have to flush your transmission completely at only 80k? Nissan recommends only a refill if your fluid is low due to sippage or leakage, did u have other problems?

No. No problem. When I repaired my left axle seal leak, I did not like the color of the cvt fluid--dark old motor oil type-- that came out of it and decided to flush it months later. Its just for my piece of mind. See, I plan to keep my MO for atleast 15+ years if no major repairs arise. Call it what you want--preventive/over maintenance, etc....Atleast now I know its not gonna be the fluid that will cause its failure. I posted the cvt fluid flushing somewhere and had pix on it. You can find it if you do a search.

There are 2 camps regarding cvt fluid change. One is to just maintain proper fluid level and the other is changing the fluid (either drain and fill or total flush). Lots of posted discussion on this topic. Including putting a totally different fluid after draining the old one. Look for it.

ok...I just bought a 2003 Nissan Murano - this was before I heard of all the problems..I bought it cos I normally thought that Nissan's were like Teflon, not knowing that Murano was a different story. So any thing I learn to help maintain mine I always listen to. Thanks.

LOL, Nissan is like Teflon, except that Nissan does not permit repair of CVT, only its replacement, which is costly. Just maintain the car the way you should and everything will be fine.

Thanks for the advice everyone. I am bringing the car into the mechanic tomorrow to have some other work done (replace steering rack and Bank 1 Catyltic converter) and will discuss this issue with him and request the flush and refill.

Njjoe, perhaps u can help me answer this questions as I have been getting my knowledge from you - thanks.

I plan on driving my 2003 Nissan murano an average of 6,000 miles annually here in Nigeria. It came with 93,000 miles, so far no transmisison problems I know of with the car. Do you think that I can avoid transmissdion problems driving it this little or will it still break down? I have contacted the Nigerian Nissan dealerships here, thanks to the information you gave me and the car is not covered under warantee for cvt as it was purchased in Canada and shipped over here in Nigeria and registered.
I plan on calling Nissan Canada to see whether there is a way they can tell me if the CVT had ever been replaced. Thanks.

DO not drive the vehicle. ATF in the CVT, in almost any amount will quickly damage it. It needs drained and flushed (no power flush) ASAP, with NS2.

I agree, flush that thing out right away. But just FYI, my sister had our Murano serviced at a local shop since it was new and once i bought it, i noticed the CVT fluid was bright red! I went through her service records and they did document adding 1 quart Dexron ATF at one time but after 120,000 miles it was still driving troublefree on the original CVT and TC. I own it now and after flushing the CVT fluid out with 25ish bottles of CVT fluid (I know, i wanted it out!) it still drives good at 124,000 miles. But its def a gamble and i'd suggest changing that out asap.
