I just checked my 09 yesterday for reference with my scanner hooked up to it. I started it and let it idle for a few minutes (50 degrees outside) took off and the trans went up to around 100 degrees relatively quickly, the fluid was halfway up the hash when I checked it a few miles later. I live in the country so I drove it another 6 miles and rechecked it, the temp had risen to 165 and the level had risen to 3/4 up the hash marks. According to the tech at Nissan that’s exactly where you want it. I was pretty consistent checking fluid from day 1 on a new 07 Murano and the fluid level was very much at the same level. I neglected the 07 changes until 80k because it was my wife’s car and she drove lots of highway miles everyday, plus it had the extended warranty. I also admit I didn’t know much about the importance, even more so than traditional trannies of clean fluid. Cvt was very much new tech for Nissan at the time. When that expired I did spill and fills with red castrol fluid (prbly 5) in a short time and that cars still running around. My 09 has a newer trans, well 43k now. But after the 1yr warranty expired I’ve been doing spill and fills every 10k. The first was using idemitsu, then eneos and since has been valvoline. No issues or abnormalities from not using oem. It literally takes 4 1/3 qts every time when drained cold. My driveway isn’t perfectly level but not extreme, so I check the trans pulled in and then backed in and split the diff which is very little. My 09 Altima had a trans failure at 95k and the dipstick always showed overfilled but the tech at the dealer that I no longer use said it wasn’t a bid deal. Turns out it was. The take away from my uneducated but my now meticulous maintenance regimen tells me “overfilled” is not good and clean fluid is crucial. The cleanest fluid in the world won’t stop a mechanical failure, but it may prevent one.mohammad wrote: ↑Mon Apr 12, 2021 11:16 amThanks for the comment!
I check Trans fluid myself. I wasn't sure about the car that is level or not , so I bought a bubble level to help to check the fluid in the level area (No slope). I guess it shouldn't be that sensitive to small slope.I drive for 10 min and then I check the fluid when the car is idleing at Park. I see fluid level is higher than the maximum. Not sure that this is exactly the right thing to check the fluid (I check many posts here to do the fluid level checking correctly).
I couldn’t agree more. Nissans new wording regarding cvt fluid uses the term “equivelant”. Obviously having the dealer do it while under warranty erases all doubt should you have issues, but after there’s quite a few aftermarkets that have proved just as good, if not better. Actually now that my 09 is mostly eneos and idemitsu my oil temp runs a few degrees cooler.casperfun wrote: ↑Tue Apr 13, 2021 9:11 amI always been on the side of caution and really believe that the Nissan transmission fluid should be treated like doing an extended oil change interval. 15-20k miles.
Because there is always a higher probability of a Jatco transmission imploding before any motor oil related engine failure imho.
