Your problem is similiar to mine . the web-site has been helpful. $2000.00 sounds way to much for repair on that vehicle with such high mileage. I went to a dismantler and bought a used transfer case for under $350.00. Did the labor myself with a little help. It's not too difficult if you have a some diy experience or ability. As your working on it stay with the web-site for install hints or go to autozone.com for repair diagrams.
Good luck have a good day.

SOURCE: My 96 Suburban will not start.
If you have a 1996 Suburban that will not start. The first place I would start is take the screws out from the cover under the ignition switch and replace the box with all the wires. That box when bad will cause all kinds of things to happen...Truck not to start. Shifts darn hard from 1st to 2nd gear. Wipers to not work at time or the wipers stop and go. You will not get the impulses to even register on a tester. After hooking up to a computer I could not get anything to register on the tester/computer as I was turning over the motor with the ignition switch...Next I decided to turn over the motor with the ignition switch and wacked the bottom of the stiring column and the puter screen cam to life....Replaced the box and never had a problum in 4 years and my truck transmision dont slam gears any more.
Hope this helps.

You should be fine to drive it home, as long as you don't drive it like that all year. There are a few things that activate the 4WD and one of the components has a failure and needs to be addressed. Good luck and hope this helps.

even though parts are new they also come with defects so it sounds as if when you turn the key you hear it working and other times not at all hmmm connections are tight ? could be faulty fuel pump or relay .

I have the same problem. It is intermittent and sometimes shows up with service transmission message. To get rid of it just put the truck in park, press the 2 high button and shift into drive while it is still flashing. I will worry about it more when it blows up. You can drive with the vehicle showing the solid neutral and it seems to make no difference. It has to be a wake up problem between the control modules. It only happens on start up.
