@AE1M....just to clarify the sever maintenance schedule, mine (2017) says to change automatic transmission fluid at 72 kilometers or 45k miles. That also goes for the Transfer case fluid. On my '17 6 speed, that's Dexron VI for both. On the transmission, I just suck out the fluid from the fill tube. I usually get about 4.5 to 5 qts, which is about half of the total fill. I do this about every 10k miles.
I personally replace (drain & fill) both both front & rear differentials at 30k miles, along with (they take a 75W90 & 75W85 syn gear oil) FYI, I use the same weight in both (75W90). Everyone has their own preference of miles for these changes. I just like to be safe than sorry.
