Nah, I just got the car Saturday and was gonna do brake flush, coolant flush and change tranny fluid. One dealer will drop the pan and add fluid but only if I sign something saying they are not responsible if the tranny craps out! They know the tranny is covered to 120k but say that Nissan wont cover it if I cant show proof of consistent fluid changes.
Hello to all! I appreciate and say thanks for all replies in advance :-)
So I am the proud new owner of a 2010 Murano LE with all the toys available at that time. It has 110K on the clock. So as part of the maintenance I do on any used car I acquire, I go to Nissan to have the trans fluid changed. Long story short, I get turned away based on the mileage and no history of prior CVT fluid changes.
So I do research and find you are supposed to check it every 30k and change every 60k. Assuming their concern is stirring up and recycling gunk back through the transmission possible causing failure.
This being the case, instead of just a dump and refill, wouldn't dropping the pan, cleaning out what's in the bottom of the pan, changing the pan gasket and trans fluid filter take care of the bulk of any accumulated sediment in the system and thereby reduce the risk of transmission damage? I know the trans cooler will have some gunk too but would that be a major concern?
I really want to change the fluid but not at the expense of damaging the transmission. What are everyone's thoughts? Please note I do not currently perceive any issues with the transmission at this time...this would be purely preventative maintenance!
The transmission does have a filter. If it's like my 2010 model, it is located externally at the front left side of the transmission, best accessed from the wheel well. It cost around $15.
I completely exchange the fluid by accessing it at the cooler line. It's an iterative process of starting the car to pump out the old fluid and refilling through the dipstick, until the fluid comes out clean.
I don't know anyone, including shops, that do power flushes on transmissions. At shops the machines simply exchange the fluid under the power from the transmission... no more forceful than operating conditions.
For a neglected transmission there may be some truth to loosening deposits.
