sounds like the vacuum lines are either pinched or the vacuum pump is shot. try getting a mechanic look at the lines on and around your transfer case... also try checking the fuses for the 4wd selector. let me know how it goes

i would try to get down to the linkage adjustment and see if maybe it is not adjusted properly or if it jumped out of alignment. Place the transmission in park and the selector in park after loosening nut and then tighten down the nut.

I would start with a transmission fliud and filter service.
I would then have the trasnmission checked out by a transmission shop. The transmission most of the time has the direct drum band is starting to go. The shops can rebuild it no problem, This is a very common failure wiith the trasnmission.

Testimonial: "Thanks alot richtko94'! I'll try that!"
The shift down linkage on the carburetor below the gas pedal cable might need to be adjusted to increase the hydraulic pressure on the internal clutch plates in the transmission it shows you how to do that in a car manual.
