So after my experience with changing the transfer case fluid on my 2011 I'm looking to do an "early" change on my 2018. Interestingly, the manual is now specifying Mercon LV for the transfer case instead of the "transfer case fluid" (aka old Mercon). Did they change anything in the transfer cases between 2011 and 2018 or is this simply to appease the EPA gods? Thoughts on whether using a Mercon vs a Mercon LV fluid would be better long term- or if it would even matter?
