Matt, be careful! If I'm not mistaken, the transmission should have gear oil in it and the transfer case should have ATF. They are not interchangeable! Check your owners manual to make sure.
The synthetics are good, I use Valvolene synthetic gear oil in the tranny and Aamco synthetic ATF in my t-case. I highly recommend the synthetics.

<font color=blue>lowrange</font color=blue> is right. Gear oil in the tranny and ATF in the transfer. I use Mobil-1 (synthetic) in both of them, and no problems with either after over 70K (changed once in that time).
