' Data Monitor Aux Box has slip'
They are telling you the chain is slipping on the drive pulleys, probably your shuddering.
The rest about signing off on old trans fluid change..........................the entire industry is going that way to scare people into new transmissions. It comes from oldschool non-CVT types driven way too long with no fluid changes then the owners freak out to want a fluid change when it is too late. The problem being that by then there is enough metallic particle in the fluid to then have it act partially as the clutch disc, and a fluid change at that point then removes that to have the trans slip horribly as soon as the fluid is changed. The shops quit doing that because owners blamed them when the trans went out all the way.
Pretty much the entire industry does not want to mess with minor internal details either, such as what I do, I have recovered transmissions that I was told had to be changed by simply readjusting a (non-adjustable) band or such that got out of range or changing solenoids to make the car then run for years longer with zero issues. They don't want to bother with things like that, in today's world it does not provide enough shop money and almost everybody steers toward the complete trans change now to get more cash. Nissan does no physical fixes in the field at all other than complete trans changes and makes sense since the thing that wears most in a CVT is the belts and pulleys and you have to bust them down to get to that anyway.
CVTs are super simple as compared to oldschool clutch pack trans but the flipside is that you only have that chain/pulley interface to get you home, once that is dead the rest of trans is as well. On older types often another gear would get you home and save the towtruck cost. It's in Nissan's best interests to keep CVT sounding super technical and all magic as well, it makes selling entire trans changes more edible than it would sound otherwise. A major reason why the trans dipstick disappeared and you have to jump over all the monkeys to change your own fluid nowadays, they took that away from you. You still have to change fluid the same way you ever did but they changed that up horribly to force more dealer work into the shops. Charging pipe set.......LOL, ridiculous. All that extra effort to save the price of a dipstick and fill tube to give it to the CEO in a bonus for taking away more self-done work from owners to give it to dealers.
