Having hit 60K, I thought I would pull the CVT PPM while having the drive belts changed. There is still so much shoulder shrugging at the dealerships about that CVT fluid. The mechanic said probably change at 100K, a service advisor said 60K and someone else had another answer. We all know that story from all the opinions on the forum. No one can agree, it has always been said check the PPM to determine.

Anyway, I was looking for a reading under 210,000 or something as we had brought that up many times.

The advisor called and said the machine has a reading of 47 and recommended level is 21.

I can only assume it meant 21=210,000.
I'm OMG, is this really reading 470,000? I remember NJ Joe (I think) said no one came near the 210,000 as of yet.

Running OK, I changed fluid at the dealer but those numbers gave me a jolt. Service advisor could not translate as I knew more about the CVT than they did.

bob1-

My guess is that the guy was not reading the correct number or was not performing the correct test. Did you see the actual readout?

No Joe, saw ticket where he wrote number 47 and recommend at 21. The tech was not available to have a conversation.

Anyway, 60K, probably wanted to do a change there anyway, I can't imagine I was at 470,000 PPM, no way, no how.

Just thought it may be a good idea for those around the 60K marker to have them check CVT numbers when in for service.

sorry but whats PPM?

sorry but whats PPM?

PPM= Parts Per Million

Did you have them do the readout after the oil change, just to compare?

 

[njjoe]

PPM???

I should have caught that earlier. The "CVTF DETERIORATION DATE" is a unit-less number. It does not represent hours, parts-per-million, miles, or any other unit.

According to the service manual the CONSULT-II checks the “CVTF DETERIORATION DATE” to determine the remaining life of the CVT fluid.

The Nissan/JATCO engineers could have avoided a lot of confusion if they simply added "/2100" to the “CVTF DETERIORATION DATE” calculation. That way "0" would be the starting point and "100" would represent the end-point. People would better understand 0 - 100% of useful life.

That's what happens when you lock a bunch of engineers in the room and don't let them talk to people in the real world.

You are perfectly right Joe. Unfortunately there is a lot of confusion and dealers take advantage of it. Sad story.....

Whoa, never even crossed my mind to ask that. They seem to make a big stink that there is only one machine and last time it was tied up and they could not check. I assumed they just put a drop on some reader machine.

Also thanks Joe for clearing up the mystery on the numbers.

bob1; did they at least tell you how many qts. they put in? Just wondering if they did a "drain and fill" or a proper "flush"?
Thanks.

You know John, I have had so much going on that I never took a look till you asked. It does say Drain and refill and shows Unit number 6 at 19.99 each meaning that was 120.00 in fluid. I assume that is quarts?

Now I wonder, we basically have just 2 cones and 2 belts in there. I can't imagine that there is all that mess like a standard tranny where the fluid is spread out in a more complex housing. Do they even offer a power flush like a standard 4-5-6 speed tranny?

How about others that have CVT serviced? Power flush offered by any dealers? I just don't know the answer.

bob1; a proper flush and fill requires approx. 10.1 quarts. I did the drain and fill this past fall and I too put in approx. 6 to 7 quarts. I figured that doing some is better than doing nothing at the time. My MO has 151,000 km on it and I do tow a trailer often so I wanted to error on the safe side.
BTW- the Nissan dealers up here want $38.00 per quart! LOL.....
I ended up driving down to NY (1 hr to a Nissan dealer there) and picked up my NS-1 fluid there....

the dealer was full of BS. My understanding is that the readout is done by Consult. Basically Murano computer calculates this number and stores in the memory. Consult just reads it. No fancy analyzers, sampling etc.

6 qt - it is simply drain and refill. I know, dealer will talk about flush but actually what they do is drain and refill. It is very misleading to say the least.

Murano service manual does describe full flash so it is possible and this is what the dealer should have done. For DIY though drain-and-refill should suffice especially with CVT.

 

[bob1]

BikerJohn, guess I won't ***** about 6 quarts at 19.99 each after seeing the price in Canada...sheesh!

Kris, good info to know. Guess I do feel better about having it done.
My ticket does in fact state drain and refill, they never insinuated flush.

I was the one that requested they do the analysis on it. I still don't know about those numbers seeing 47 and it should be at 21. Biker kind of cleared that up but not sure if that 47 was harmful, I hope not.

I'm hoping other members ask the dealer to check numbers and post the results here when they do. I would like to see some base line comparison.

I had my 60k service done last Wednesday. They told me that they NORMALLY do not do a flush of the CVT fluid due to cost (they just drain and fill instead), and will only do it if specifically requested or if the consult II specifies that the fluid was particularly bad. Note that this is NOT a Nissan dealer, this is Greg's Japanese Auto who I trust a lot more (not completely, but far more than Nissan. They've always treated me right).

Anyway, they also used 6 quarts. He told me that their "book" specifies 5, but the mechanic had to add another quart to bring it up within the lines on the stick. They charged me $22.95/quart here in Bellevue, WA. They don't list any of the consult numbers on the paperwork, and I didn't ask at the time. Would have if I had thought about it.
