Hi guys,
Thanks for the additional info. Although, I did not find specific info on how-to change the transfer case fluid, I did find that many here recommend doing a reset of the transfer case computer.
Which, can only be done at a BMW dealer or an Indy that would have the proper software.

Any of you have done the TC fluid change without doing a reset? If yes, how many miles ago?
It seems that reseting is highly recommended as the TC will re-learn based on the new fluid viscosity, etc.
Depending on your answers, I guess I won't be DIY my TC Case, and leave that for the dealer. Maybe I can get a discount since I already have the fluid from ECS Tuning.
