Hi all,
Need some advice. What would be the consequence of having too much CVT fluid in the Murano. I've checked the fluid in my car, it is right at the letter T of "HOT". I've the the fluid with the car running (after it has been driven about 10-20 mins). I went thru all the shift modes (e.g. Neutral, D, DS, L, P) and then measured the level. The car was parked on even surface.
I recall the fluid being added about a year or two ago. Could a high level of fluid cause damage? The fluid color was clear on the dipstick but looked a bit brownish on the paper towel.
The reason I ask these questions is because I get this drivetrain vibration at 2000 rpms. It goes away below and above that. It is really annoying and I fear that there may be something going on with the CVT.
Also, this car has hit a tracker trailer tire at highway speeds and is therefore missing it's plastic transmission cooler scoop.
Also, the car has 65k miles on it. |

myMoo,
Although, I am no expert by any means, I would say that if it reads above "MAX" than it is over-full and needs to be removed. You can probably do it yourself by just buying a siphon hose with pump and sticking it in the filler tube.
However, my question is, who added the fluid and why? If the fluid was not the proper CVT fluid by Nissan then it may be causing your problems. If you are not sure, quickly get it replaced. The fluid is recommended at 60K miles for inspection and possible replacement anyway. Also, replace the trans scoop.

I doubt you would have any problems due to overfilling the tranny. Unlike the engine oil, you do not have to worry about a large rotating mass (crankshaft) splashing into the oil reservoir and aerating it.

I doubt being overfull by that small amount would lead to any damage. Remember that certain tolerances are built into any mechanical component in a vehicle and usually normal operating conditions only span a small range, not even close to reaching maximum tolerance.
I think if the overfull fluid was causing any issues, you would have noticed it immediately after the fluid was changed, not 1 to 2 years later. |

Thanks guys for your input! Put my mind a bit more at ease.
biggun,
I am going to replace the scoop as you've suggested. I am also going to have the fluid changed (I may do it myself, as it doesn't seem all that hard and I don't want to shell out 300 bucks). As far as the added fluid is concerned, I can't remember what the reasons were why the fluid was added to begin with. Perhaps, someone read the level wrong? But I am certain that it was NS-2 (sp?) that Nissan recommends. |

You do realize there is no need to replace the CVT fluid, especially after only 65,000 miles.
A partial drain and topping off of the CVT fluid is relatively simple as compared to a complete drain, flush, and fill. The latter is quite expensive as it requires extra fluid for flushing of the heat exchanger.
