2010 Murano CVT fluid change question

Hello to all! I appreciate and say thanks for all replies in advance :-)

So I am the proud new owner of a 2010 Murano LE with all the toys available at that time. It has 110K on the clock. So as part of the maintenance I do on any used car I acquire, I go to Nissan to have the trans fluid changed. Long story short, I get turned away based on the mileage and no history of prior CVT fluid changes.

So I do research and find you are supposed to check it every 30k and change every 60k. Assuming their concern is stirring up and recycling gunk back through the trans possible causing failure.

This being the case, instead of just a dump and refill, wouldn't dropping the pan, cleaning out what's in the bottom of the pan, changing the pan gasket and trans fluid filter take care of the bulk of any accumulated sediment in the system and thereby reduce the risk of transmission damage? I know the trans cooler will have some gunk too but would that be a major concern?

I really want to change the fluid but not at the expense of damaging the transmission. What are everyone's thoughts? Please note I do not currently perceive any issues with the transmission at this time...this would be purely preventative maintenance!

Strange that a stealership would turn down service from an eager customer. Very strange indeed.
Did you contact more than one stealership?

Anyway. I think you'll be okay doing the fluid change if you drop the pan, clean everything, and use new parts as you're planning to do.

You do know this is not a simple drain and refill operation, right?

Approximately 12 to 15 quarts will be needed for a complete swap of old to new.
The transaxle holds 10 quarts.

Nissan made it easy to change out the trans fluid on the 2nd gen however
you should get the service manual before "digging" in.

My 2 cents for what it's worth.

Hi junior82. Two dealerships turned me down. One would do it if I signed an agreement absolving them if the tranny crapped out. I was "guaranteed" that if I drained and refilled the fluid if it had never been changed after 110k that I would end up having to replace the tranny. Even though this is a Gen 2 Murano there is no way I would attempt myself! Even though the tranny is covered to 120k they said if I had had fluid now and it died in the next 10k miles that Nissan wouldn't cover it...

Two of them. Wow!

And they guarantee that your CVT would fail with new fluid? Nonsense!

You should not be afraid of doing this maintenance if you've done other fairly common things like brake service, MT clutch replacement,
timing belt replacement, etc. I have done all of these and more.

I understand your reluctance if you don't have the skill or experience.
Not everyone has a garage and the tools.

Seems like these a-holes at Nissan want your CVT to fail so that they can really clean up installing a rebuilt P.O.S. unit.

If a Nissan stealership won't touch it, there are ASE certified mechanics that can do the job for you and guarantee their work.
Personally, I would trust them over some of the wrench turners at your average stealership.

Yup that's their "guarantee". And you are correct...I have neither the garage or the tools to attempt myself! I'd be happy to buy the proper stuff and have a certified non-Nissan tech do it...but dont know if that would help me or hurt me if the tranny failed lol.

What side is the external tranny filter on?

What side is the external filter on? That I don't know for your Murano. It's usually by the oil cooler on the CVT itself when it has a bolt on oil cooler.
Not all Jatco CVTs have them.

Here's a link to the CVT section of the service manual if you want to see if it has one. I couldn't find it. Maybe you'll have better luck.

The fear of getting blamed when the trans goes bad is why they will not change fluid well past the due time. Too many lawsuits happen that way and on normal ATX as well as CVT type.

People who don't know spit about transmissions (not saying that here) then change fluid when they begin to slip and then the trans continues fully into the fail as trans fluid does not stop that. Next up they blame the person who changed the fluid last.

Most trans shops on the street now do the same thing, they turn down work at higher mileages when no changes were done earlier, it is begging for a problem customer.

With the wildly erratic record Nissan CVT has the trans may last forever or shell out tomorrow and the shops know it. Fluid changes help but do not radically change that.
