Hey guys,
Been doing alot of reading and think I sank too much and pretty much got lost along the way. I serviced my TB with an Engine Oil Change, Transmission and Filter change, Rear and Front differential Oil change. Is there an oil change for the 4wd system itself or is it the same as the Front differential oil? :redface:

Sorry for the noob question. 4wd systems are way out of my league and completely new to me. :crazy:

Check your Owner's Manual (a good idea to read it cover to cover at least once). The Transfer Case needs its fluid changed every 50K miles. Very, very important, and the only fluid allowed is GM Auto Trak II. Two liters needed. Just search for "transfer case fluid change" and watch the video:
