My 2009 LE is just over 210k KM and I’ve never done anything on the CVT.

I bought it 4 years used at 77k KM 7 years ago and when I hit 120k the guy at Mr Lube tried to sell me on transmission fluid. I called the dealer to ask if it’s been done since I wasn’t the first owner and he replied we haven’t done it, we don’t do fluid flushed on the 09 Murano cvts. He said the new fluid can actually cause issues and that an older CVT can benefit from some of the grit.

I did a bunch of research on here and a lot of people are doing drain and fills and talking about how no fluid is truly life long.

So my question, should I do it? Should I have it serviced? My last trip to MrLube, the guy there pulled my dip stick to show me it was low on and how black it was. Do I run any risk of killing the CVT?

Thanks!

I think the grit theory pertains more to conventional automatics...

The fluid level should not be low unless you have a leak somewhere, the fluid in the CVT does not get consumed like motor oil is.

I think doing a drain and fill is good insurance, especially if you drive a lot in an especially hot or hilly area. There is a fluid deterioration counter for the CVT, for what it's worth, that gets incremented when the temperature is high. A dealer can do this for you. Or get the Android app called CVTz50 off Google Play, and a Bluetooth OBD3 dongle, and it will display it for you. A figure over ~200,000 is supposed to indicate it's time to replace the CVT fluid.

Make sure they use Nissan NS2 CVT fluid, conventional automatic transmission fluid will destroy your CVT.

I think grit being beneficial in the transmission is a bunch of hogwash. If that were true, the original fluid would be blended with grit in it.

Yes, I personally would do it. I do a drain and fill every 30-60k. I have 334,000k and tow a 3500lb boat in the summers and my transmission is still going strong!!!!

Just to be clear, I personally wouldn’t recommend having Mr.Lube do it and definitely wouldn’t recommend a flush. My recommendation is to do it yourself (drain/fill) and ONLY use the fluid directly from Nissan. If you are not comfortable doing it yourself I would only let Nissan do it as I wouldn’t trust anyone else not using OEM Nissan fluid.

with that many miles without a change, i'd just do a drain & fill rather than a total fluid exchange. be sure to change the external filter also. it should require ~ 5+ quarts fluid total so have 6 on hand. use only genuine Nissan ns2. this is a relatively simple & straight-forward procedure suitable for any moderately handy diy-er.

I am not a handy person, but i managed to do this on my wife's Murano. Very easy to do once on Jack stands. My question is about the external filter.....what external filter?

My advice is to do a fluid drain and refill, as well as changing any filters which are needed. I just added a new post in the MAINTENANCE sticky post section with a link to the Nicoclub.com service manuals. Please look yours up and see what is involved. I agree that a flush is probably not a great idea, just a drain and fill.

All lubricating fluid eventually wears out mechanically. "Grit" is NEVER a good thing in any lubricating fluid, period, end of statement. The very term is antithetical to the purpose of lubrication. In addition, over time fluids collect contaminants, which is part of their purpose. Changing fluids provides fresh lubricant which isn't broken down and has no contaminants.

The filter is located external on the transmission. It is on the driver's side toward the front, best accessed through the wheel well. To see what it looks like, look for a picture of the replacement part on Rockauto.

I didn’t even realize there was an external filter for the transmission and have been changing my my fluid regularly.

Yeah there is an external filter. It is not located inside the pan like on other cars. It's cheap though like $15 or so. I would recommend a drain and fill with ns2 buy it if Ebay or something make sure its genuine nissan. Change the filter. Do another drain and fill after 10,000 miles with filter. Then do another drain and fill with filter after another 10k miles. Then every 30k miles. Since we are on the subject, dont forget the transfer case and rear diff that use a different fluid, gear oil. Check your owner's manual for capacities and correct types of lubricants to be using. Mine is a 2010 le and I needed 80w-90 gear oil 1quart used between both the transfer case and the rear diff. 12mm offset wrench for the transfer case filler plug and dont pull the drain plug until after you have pulled the filler plugs. Fill with car level using a hand pump that screw into the top of the quart bottle and replace the filler plug with grey rtv sealant on it. The rear diff requires you to slide the plastic evap out of the way where theres a hole in the frame to fit an allen socket through to the rear diff fill plug.
