In my 06 ML350 MB shows the same part number for 722.9 fluid is to be used in the transfer case.
Is this for any other reason other than keeping it the same atf to avoid confusion,because there is not that much in there that would require such a special fluid that is used in the 7 speed electronic trans.
Also would anyone know how to tell a single speed transfer case from a 2 speed type the single uses a half quart and the 2 speed uses 1.5 qt of atf
