Auto trans in 4wd

I've searched the forum and if this has been addressed already, I apologize.

Anyway, I have a YJ with the 4.0 and automatic transmission. When I'm in 4wd and running trails, should I have the transmission in D, 2, or 1? Does it make a difference if I'm in 4 hi or 4 lo?

Thanks, I appreciate it.

I usually keep it in 4l unless I get on a dirt road and need to go over 20. Any slower and there is no reason not to be in low.

When I'm in 4HI, I put it in D. In 4LO I keep it in 2.

If you are descending a very steep hill or trail, you definitely want it in "4lo" and "1". That will get you the best traction and engine braking. Depending on your gears, you may not even have to touch the brake pedal.

When running everything but the steepest tightest trails, with the exception of down hill grades, I usually have it in "4lo" and "2".

In the sand dunes it's 4hi, and whatever gear keeps me going!

All this depends on your Jeep, tire size, and gear ratio.

Thanks, guys, I appreciate the input. I should have mentioned that my Jeep is bone stock except for removing the rear trackbar.

I'm getting the idea from here and conversations elsewhere that there's not a hard rule on the matter, but personal preference. I can see though that there are definitely better ways to do things, especially on hill descents.

I'm used to a standard shift. This is my first 4wd with an auto. All the feedback is greatly appreciated.

It's an adjustment going to automatic after a manual. Biggest thing I had to get used was braking .... or how to keep from doing it. I got used to using the E-brake handle instead of the pedal, especially for down-hill maneuvers. Now I'm back to a manual with my YJ. There are good points either way, but I prefer the manual.
It's a Jeep Thing ... I do understand!

The driver's side mount broke on a really flexy trail and it started working better (although with a new rattle). I didn't see a point in rewelding the mount for something that kept the Jeep from working as well so I just took it off the other end. No more rattle!
