I put the truck in neutral, like you should, i bring the truck to a stop, and i push the 4lo button. It flashes for about 5-10 secs but then goes right back to 2hi, I've tried rolling about 2-3mph and it still won't even engage. Its a 2002 chevy avalanche z71, with the 5.3L V8. Sometimes when i press it, it engages no problem, but other times, it just flashes and goes right back to 2hi. When i press 4hi, it goes right in, but 4lo is giving me some problems.
