So i took my z out to the river about 2 months ago and gave her hell, the sad part it returned it on me i burned out my transfer case clutches and lost 4wd and ended up being towed out by a ford (not cool) anyways so i just got me a used transfer case and now i got no 4low does anybody no wat could cause this or wat i need to do it is the auto 4wd set up and it switches fine into 4 hi

 

dont know the answer, but that just happened to me to, goes into 4lo and wont go back to 2wd or 4hi. stays stuck there.
