I hope this questin isnt the dumbest thing you guys have ever heard. I just bought a 75 W200 PW with fulltime NP203 case behind the NP435. My question is why is there 4HI and 4HI Loc if its full time already. I tried to drop it down into 4HI but it wont go there. I have no trouble getting into 4Lo which makes sense because HI is what it would be in already with the fulltime right?

Thanks,
Paul
