I just paid a grip to get the tranny fluid flushed for my 2009 max, the dealer paperwork states "dexron 2" and another paper says CVT fluid.

they claim it's exclusive to nissan by I'm calling that a bluff, what is this fluid they use ? is it really "exclusive" or can u get this stuff at any auto parts shop if u know what it really is.

 

A quick google says no.. it's not exclusive to Nissan. I'm sure someone with transmission fluid knowledge could go into more detail, but it looks like Dexron isn't even exclusive to transmissions anymore. In fact it sounds like just a standard rather than a specific type of fluid.

 

ya some truth behind this tranny fluid thing would really help.

 

u guys think 289 bucks for a tranny flush with dexron 2 fluid is reasonable ?

also, some websites are saying a flush is bad for the internals of the transmission, and the nissan maintenance info "reccommends" a tranny flush but not mandatory for warranty purposes.

 

Well lets just say that every single time (3-4) i got a tranny flush, a couple months later I always had problems. I refuse to do them any more...100 percent failure rate is to much for me to play that game of odds......

 

A tranny flush is sort of like surgery. If it goes well, the patient (car) is better for having it done. If all does not go well, the patient (car) may be worse off than before.

Tranny flushes have been known to dislodge impurities and particles inside the tranny, which can result in them lodging in tight places, impairing the passage of tranny fluid through small passageways.

I usually request that the service folks remove and replace the part of the tranny fluid they can siphon out, but not risk messing things up by flushing the entire tranny. This is considerably less expensive than a full flush.

I always have my tranny fluid replaced every 60,000 miles. Unless one is doing a lot of driving on dirt roads, or is driving the car very hard, changing more frequently is making the driver feel better about things, but having little effect on the car. Those who drive their car hard, or on dusty roads might consider changing at 45K, or maybe 30K in very extreme conditions, such as elapsed time runs or frequently pulling a trailer.

Of course the 20,000 folks reading this board will have 20,000 different opinions about when and how to replace tranny fluid.
