Not sure on the transfer case, but the trans is most likely a 4L60E, an electronically controlled 700R4 basically.

I would check into the basics first: plugs, wires, cap, rotor, etc. Check the fuel pressure, compression, and timing. Is the check engine light on? If so, read the codes and see what's going on.

You may actually get more help with this in the newer trucks section (88-98 I think?). I know it's just listed for pickups, but your Burb will share the same drivetrain.
