If a fault code is reset from the fluid being out of spec (as determined by measuring slip and engagement pressure) then that has to be reset.

If the fluid is changed prior to that code being logged, then it is just the adaptations.

What has to be done additionally when the transfer case is being replaced is that the vehicle needs coding related to the classification resistor.

Here are some sources.

This next one is about the X3 (which uses a different version of the same transfer case, same technology)
