Sorry I got distracted.
I do have something for you to check.
Do you have an oil pressure gauge that will go to 600 PSI?
You can screw that into the plug on the side of the trans and
see what the pressure is. Look at as you shift through all the ranges.




At about 3:00 in you will see a problem in this one.

Found a copy I had hidden in the wrong place.
Here you go.
I attached 5 PDFs for you to look at.
I need to get the pinpoint testing one also. It helps
when you are at that step to have something like the
IDS but I think you may be able to work around that.

Ok and now for the deeper stuff.

BTW I got the pressure gauge made at a hydraulic shop near by.
It did not cost much at all and is very handy.

Also I have been trying to research it but not much luck. Can this really cause the problem I'm having with not engaging into any gear?

Try shifting it to 4 lo and listen for the motor shifting. Can you hear it? Now try putting the truck in drive and see what it does. Post results.

I really think you have an electronic issue.

Is your problem in the transfer case or the transmission? If it's in the transmission, changing anything in the transfer case is a waste of money. What are your transmission pressures? That can tell us if the transmission is working or not.
