Welcome to CF!

I'm thinking it's a 242 because he's talking about Full Time 4wd.

DLC24, if it's the np242 Selectrac, The shifter says 2wd, 4wd part time, 4wd full time, neutral, and 4lo. There's a detent stop on the shifter where you have to move the lever sideways to get to neutral and 4lo. Shift it "smartly" from 2wd to 4wd full time until you hit that stop. If everything is adjusted right, it should go in. Don't baby it but don't slam it either. It's best to shift it on a slow roll until you get familiar with it. Shifting into 4lo takes some practice as well because it's not syncronized and the speed of the gears have to be matched carefully. That's best done with the transmission in neutral or park when fully stopped. After you get proficient at it, you can shift it on a slow roll.

4wd part time and 4lo should only be used on loose or slippery surfaces. You can try them as long as your going straight. Turning in part time will bind up and cause the tires to skip or hop.

If you're not sure what you have and you want to crawl under it, there's a round red&silver tag on the back side of the transfer case that tells you what it is.
