CVT Fluid

[mellobudd]

Hi folks! I have a 2005 murano with 229k kms on it (149k miles?) and Im wondering if I need to change the cvt fluid? The transfer case was replaced via extended warranty in 2011 so I am not sure if the fluid was already changed?

Any comment is appreciated!

The transfer case is a different unit and only married to the transmission however it does not necessarily mean that the CVT fluid from the tranny would have been changed. If the dealers who fixed the TC is reputable, they would have done the right thing and changed both fluids at the same time.

Thanks for the reply! So would you suggest the cvt fluid change then? Or wait? How do i know if i need to change? Color? Viscosity? Can't really tell from the transmission's performance though im hearing a weird crumpling like sound coming from underneath, like its from the shaft or something? The sound is not there all the time but can be annoying when its there.

i would changed the CVT fluid. Even if the shop changed it with the transfer case, i would do it to be on the safe side. I would rather waste $200.00 on CVT fluid I may not need, than possibly having a $2000.00 CVT repair job a little later down the road if it was not changed before.

I would change the fluid based on the mileage you have.The CVT is still a transmission, and it do need fluid that can do its job to keep it working properly. I believe changing the CVT fluid every 30K miles will keep the CVT lubricated and running strong.

Noted! Now, would a regular joe mechanic do this kind of job? Should i buy the cvt fluid from a dealer then have it done by a trusted mechanic? Im going back to my regular guy for some maintenance and if i could have it done at the same time why not right?

a drain and fill is simple enough for anyone to do, especially a mechanic. Some prefer flushing all of the old fluid out through the cooler pipe, which is more expensive and a little more complicated. I prefer the drain and fill. But the flush will be more or less a one time job for at least 100K miles due to having all new fluid.Talk with your mechanic and see if he has any idea how to change the fluid, if not, find somebody who does or go to the dealership.

Cool! Thanks carguy! I'll talk to my mechanic if he's familiar with the cvt fluid change in th murano. If he hesitates, then im off to the stealership. I guess it would run me around $300 for this job from the stealer?

You are welcome. No problem. Yes, the stealer will hit you hard because of the labor costs. Try some local import auto shops first, the nissan CVT have been around for a while, so most import shops should have experience servicing them. good luck

If you can change your engine oil, you can do this also. Do a search. Lots of info and diy on the entire procedure.
