so i used the wrong transmission fluid in my 2014 maxima drove on it for about 2 days my fault i didnt read the car manual i thought all cvt oil was the same, i now have 5 quarts of genuine ms-2 oil from nissan and im gonna do my oil change my self again today, is there a way to do a flush to get old oil out?

 

It's NS2. Not MS-2

The safest way is to do 2 to 3 drain and refills, maybe few days/200-300 miles apart.
CVT transmission holds 10.8 quarts (total). You're only getting 4-5 quarts out each time. Consider replacing the external filter too.
Will be costly, but a dead transmission will cost more.
Beeline Parts have good prices on CVT NS2 Nissan fluid.

What's your mileage? is this the first time you drain the CVT?

 

yes you are right its ns-2, what do you mean by 2 to 3 drains and refills? i have to go to nissan and get the filter i just bought the oil from them. and thank you for that website thats like 30 dollars cheaper than the dealership

 

With each drain and refill you'll "dilute" the wrong or dirty fluid, with new fresh fluid.
I once got 10 quarts from Beelineparts.com, They ship fast and fluid was legit.

 

what is the external filter you were talking about does beelineparts have that part on the website.
ok so like for example today, i drain the old bad cvt oil and replace it with 4 1/2 bottles. then each day after that i drain 1 quart and replace a quart?

Part no. 31726-1XE0A. Ask deleaer and see if beelineparts.com has it
You drain and refill completely each time, you'll loose good fluid each time, but that's the only way to do it.

 

so ive managed to change the oil with the right oil and it fixed the whining noises that the cvt was making but after a few days its now its making the noise again, i used 5 bottles of ns2 cvt oil. should i drain out the oil again and put another 4-5 quarts back in or do you think the transmission is done so

 

Unfortunately I think Imo that CVT is done, Usually the whining noise is an early sign that the CVT is on it's way out. I know someone who's 2012 had a whine that started at high speeds and he too did a drain and fill only for the whine to return and shortly after while driving " on the highway " the car suddenly lost power as the CVT went into limp mode and check engine light came on. He got it towed to Nissan and they confirmed the CVT was done. I believe the want like $3800 or something along that range for a new CVT, Car only had 95,000 miles on it and he opted to trade it in and got something else. Was your car whining before you did the drain and fill with the wrong fluid or did it start after?

 

What was the "wrong" fluid?

 

i used oriellys brand of automatic transmission in the car for about 2 days then the whine started happened then i put 5 quarts of ns-2 and the whine instantly went away now its back when i accelerate it whines

 

yeah i think so too. my car is paid off so i think im just gonna buy a new transmissions for it

 

I entered the wrong fluid because i went to oriellys and they recommended their brand and the mechanic i took it to didnt know any better so ima just have to take a L on that old cvt and cop a new one

 

Seeing that it wasn't whining before hand means that the fluid you put in contributed to the whining. The manual states you can use equivalents for coolant, brake fluid, and power steering fluid but states to only use genuine Nissan NS2 fluid for the transmission.

 

Do another drain and then refill with ns2
Cheaper than 3k+ tranny

 

yeah thats what i was thinking aswell, i cant even be mad about it since its my fault. but i bought some ns2 and it stopped whining for a day now its back to whining https://imgur.com/a/6MEehbl gonna try to do another drain and refill because it might be overfilled i used 5 quarts
https://imgur.com/a/6MEehbl

gonna try to do another one today if that dont work im gonna have to get another one lol i hate this sound https://imgur.com/a/6MEehbl

 

Is that your usual launch or just because you're sick of the tranny?

 

usual launch. heres a video with me in park and its sounds so bad lol https://imgur.com/gallery/jc6McRg

 

do a total fluid replacement (& use another new external filter too) instead of just another drain and refill. that way, you'll get 90%++ of new fluid and have very little of the old wrong crap left in the system. do by pumping in new clean proper fluid into the external filter inlet at the same time (and at same rate) as your drain it from the cvt fluid return line from the cvt cooler portion of the radiator. I left a write up of it either here or over at 2nd gen Murano.org. drain & refill pan before doing the fluid exchange part. you'll need ~ 11 quarts (you may be able to get by with just 10 and 12 will certainly be more than enough).
