There are many others that have experienced the same thing as you detailed in more than a few threads on the subject.

Start out by having a look at the 96+ NV233 diagnosis link in my signature.

the problem is related to the vaccuum line for the 4 hi. there is the 4x4 vaccuum actuator on the firewall that has 2 lines on it. i found my issue which was same as yours the vaccuum line that leads to the drivers side is for the 4 low the line that leads to the right is for the 4 hi. either its disconnected or has crack and leaking. could possibly be actuator one way to check is to swap the bottom line to the top and vice versa and see if the 4 lo doesnt go in and 4 hi does
