its pretty simple

uhm so yea your 2h is what your in whenver your driving, the 4h is for driving at highway speeds but in 4 wheel drive so lets say its snowing and your driving on the interstate that would be the best time to use it, 4L is 4 wheel drive with low gears so if your off on a trail and meet a tuff obstacle or if your trying to pull a friend out of a mud whole you would use your 4 low and N is Neutral this is my best shot at trying to exlplain it to ya hope it helps

well by 2L i assume you mean 4L. since you have just one 4H option, that means you have the NP 231 transfer case (the NP 242 also had a full time option in 4H). its a very good transfer case and common in most jeeps. it is shift on the fly which means you can shift in and out of 4H while driving, preferably under 55. but while in 4WD, you cannot drive on streets or paved surfaces since the front and rear driveshafts spin the same speed, causing the transfer case to bind when turning. so only use 4WD on dirt or other low traction situations. to shift in and out of 4L, you should be moving about 2-3 MPH but not any faster and not stopped. 4L gives most traction and torque when needed most like when climbing steep hills, rock crawling etc. N is used when towing

having 4L,why would that mean its the 231?(if thats what you meant) obviously it is but not because of the 4L, the 242 also has low, but also a part time and full time position. So yes its the 231. You can be stopped when putting it into 4Low just make sure your transmission is in N, if it wont go in the yes let it roll a little bit while trying, should do the trick. But what he said was true, the part time on the 231 should really only be used on low traction surfaces. If you want a TC that you can drive around on the street, you'll want the np242

*another thing is you cant rely on the shift plate, mine came with the 242 plate but with the 231 tc from factory.

uhm

i want to point out the fact while we are at it that he lives in hunnington beach CA so the only time he would ever be using the 4 wheel drive and driving on the road would be like for instance if he was driving to the ski resort and while he was up on the summit it started snowing in this instance you would be fine to drive on the street and use your 4 hi its just when making sharp turns that it will make you skip and jump I live an hour and a half away from tahoe and drive up to the ski resorts all the time and dont have any issues with my 4 high when i m driving on I80 now if you lived in tahoe and you were using it to drive around in town as a DD then you might want to consider changing your TC

mud you say? you want 4LO, get that extra torque to keep the wheels moving and keeps the tires spinning to clear out the mud. Put it to the floor and hold on

Ya..... its probly best if you stayed away from mud. i like it and don't just cuz the fact it gets every where and is hard to clean, also it tends to make things go wrong and really fast. just keep in mind if your driving somewhere and you think you might slide off the road cuz its slippery then engage. and dont go over 55 in 4 high and dont go over like 35 in 4 low.

35? Really? I'm not saying you're wrong, I've just never heard that. I don't think I'd go faster than 15 or 20.

Fastest I've gone in 4 low has been about 3. That was on the beach because the gearing is crap until I can afford to change them.
