FWIW if you have the electronically controlled transfer case (switch on dash) you have an NV273 case.

The best way to test it that I know of is to find someone with a good scanner and gen into the trasnfer case module and see what it is doing when you move the switch to 4WD. See if there is any codes or if it says selector switch error or something like that.

Sorry thats all I got.

Alright than, yes you are correct. Floor shift is a 271. How does the shifter feel? Does it feel like there is any resistance at all to it when it goes into 4H and 4L ? Does it drive at all in 4L or does it seem like it is in neutral? How about 4H.

i can only get it into N and 2wd... i cant move the shifter to 4hi or 4lo... the shifter just stops and wont move.... like something is blocking it from going into gear... i never opened this kind of Tcase so didnt wanna take it out if i didnt have to... but looking like i need to...

depending on your climate + driving conditions it is very easy for mud/dirt/crap to get in the way of the cable linkage on the tcase.

When i first got my truck it wouldn't shift into 4h or 4L, so i put the shifter back into 2H and just rammed it forward into 4H with quite a bit of pressure and it went right in. After i hit 4H, 4L was no trouble. After initially going into 4, it seemed to move around much better.

Now when I say force it, im not saying put your back against your seat and use your feet against the shifter to force it. Just use your arm and give it a good jam in.

This is of course after going underneath and making sure that nothing is jamming the linkage operation.

Let us know.
