I have an 85 k20. so i was wondering did they make any np205 that are full time full wheel drive. I was doing some work on my transfer and put it all the way forward which should be 4lo everything was good, then i pulled back it was nuetral, then pulled back again and two wheel drive. well thats all the pulling i can do, so i put it back forward to see if i was just missing a gear but it alwys went from lo to nuetral. i dont know anyone have an idea.
