Dmaxalli Tech, I am pretty sure we don't have an AutoTrak II system. The transfer case uses normal Dexron III ATF IIRC. We went through this about 6 months back. The manual is misleading in this case and many folks were confused. Hoot, Mac, JK, One of you intelligent guys back me up or shut me down. I need to change mine again if I'm wrong because I have transynd in it.
