It's my understanding that in the 4Matic in my w166 the transfer case is integrated into the transmission. Does that mean they share the same fluid? So when I change the transmission fluid it's also changing the transfer case fluid?

Is there a center differential or is that the same as the transfer case?

There's only a separate transfer case if you have the on/off road package with low range.

This also begs the question does the ML requires a TC drain like the W204 when a transmission service is done? Does the ML's TC have the mystical drain bolt that most service centers deny that even exist on the 7g transmissions?
