if you have a 15 or 16 murano, have the "enhanced diagnostic logic for cvt" done per NTB16-085 ASAP! i kinda noticed something like the infamous judder/shudder (felt like old school manual transmission "lugging" to me) upon occasion so figured i'd have the cvt diagnostic logic enhanced per the above bulletin before my powertrain warranty is up soon. as soon as it was done, codes p17f1 & p17f0 came up at the dealer; it seems the tcm is storing them but has no way to set off a dummy light or even display these codes to code-reader because it doesn't know how to/cant?! its either a sub-assembly or new tranny. only have 30K on it.
