Matt13 I've had my '13 Rubicon for about 3 months and probably have gone into 4 Lo at least 15 times. That being said, at first I too thought it was a bit rough, but I got used to it after just a couple times and now don't have any issue. Honestly, I think I got better at doing it "firmly", only took a few times. I am in Neutral rolling maybe 2-3 mph btw. It's kinda like getting used to exactly how much brake or throttle pressure you need in certain situations...it's a feel thing. Now I can hear it go into Lo (not a grind, more like a thunk) and "feel" it thru the shifter as well. If you can, maybe go to a dealer & test drive another one for comparison.

If you are simply driving in a straight line, it doesn't cause as much of a problem as turning, going around curves, etc. If the wheels are unable to slip (or hop, as some would say), a lot of stress builds up in driveline components since they are bound together in 4WD but your wheels turn at different rates going around curves. I don't think the problem would be with "burning up the tranny". It's more in axles, ujoints, driveshafts, etc. If you've ever heard someone with full-time lockers try to turn a corner on a city street, you get an idea of the problem. One tire screeches intermittently as it completes the turn...releasing the stress that builds up in such a system very fast. I had a friend break an axle once with full-time lockers simply because one wheel was unable to slip on a not-so-slick slickrock trail.

If you are driving on mostly slushy roads and need 4WD, then leave it in 4WD. When you get to the point where the pavement is mostly dry, slip it back into 2WD. I'm not a mechanic, but it seems that periodically shifting into 2WD would release any of that built up stress on driveline components. This is not just a jeep thing...it's the same with any part-time 4WD vehicle I've ever owned.

^ This.

I really had to muscle mine into 4L.

How the heck do you get in low gear?

Would you even need 4L in that instance? I thought 4L was for hill climbing and such. 4H should provide enough traction to get over a 2 ft pile of snow.

Kinda what I figured. Even in 2H I get some "scratching" while shifting between first and second gears. It doesn't matter how "easy" I shift. I may need to get this looked at.

Moabite To expand just a bit on my above post, gear noise is normal when shifting into 4L. It appears to be a Jeep thing. And videos from Jeep state that "gear noise is normal" when shifting into 4L. I think the problem most folks have is that they stop as soon as they hear gears grinding and try to finesse it in. That just makes it worse. Even the owner's manual states to shift "firmly."

Here's the Jeep Channel vid that says gear noise is normal...if I remember right.

When I have disengaged from 4H or 4L, I reverse a bit at first then go forward. May not be needed but I learned this from driving my father's 4x4 chev from years ago.

Another thing, in my opinion, it's important to regularly put your vehicle in 4L and 4H to keep it loose. Take it out on a dirt road and let her stretch her legs for a bit. All too often, folks will reach down to shift and nothing happens as everything is seized up and then you are in a pickle.

I have driven quite a few 4x4's over the years and have found my JKU to be amazing. I honestly think the 4L could allow you to climb a tree and park if need be!
My 4L is very difficult to shift into. Why would it just "get easier?" I mean, over time my manual has not become any easier or more difficult to shift, and any automatic I've ever driven had stayed the same in terms of operation.

I used to come to a complete stop and get out of the vehicle when switching into 4WD...but that was because I had to engage the manual hubs on my '82 Scrambler. Ah...the good 'ol days. In the 21st century, you can now switch in and out of 4H at highway speeds...though I always slow to below about 40-45mph when doing so.

4Lo is a different story. With my manual Scrambler, there was never any gear grinding. With the auto transmissions in my '03 Rubicon and the '13 Rubicon, there is almost always a bit of grinding when going into 4Lo. It appears to be a Jeep thing. There is NO grinding in my '08 Tundra. In the Tundra, I am totally stopped going into 4Lo and may hear a clunk...or just a click. It was the same with numerous Ford F-250s and 150s...no grinding.

Jeep recommends that you be rolling at about 2-3 mph to shift the automatic into 4Lo. Of course, you are in neutral. I've tried rolling and stopped. There is almost always a bit of grinding either way. I've found the best way to do the shift is quickly and forcefully. Do not put the transfer case in neutral and then into 4Lo...go from 4H to 4L in one smooth move. Don't be timid or slow with the shift or you will definitely get more grinding. If you hear it start to grind...don't pause. Jam that sucker into 4Lo. Shift like a man...or a woman who knows how to drive a Jeep.

Raiderfan001 I've always put it in neutral and have never had any problems going from 2H > 4H > 4L etc.
01-06-2013 06:55 AM
kdude Mine fights with me when I try to go back to regular drive...

Since a lot of guys who posted have a similar issue maybe its a jeep thing..

Its ridiculous that it should be such an issue.

I really hope others chime in and share there experience with the high to low gear change..

My girlfriend would not be able to make the change, crap I have difficulty too!

Going from 4H to 4L was a completely different matter. I know it says to shift into neutral and it is easier to do it if it's rolling at 2-3 mph but that thing took a lot of effort and I don't think it's something my wife would ever do. It's her Sahara.

Is going into or out of 4L supposed to be somewhat more difficult than the others or am I just not doing it right?
I've used my 4L once and found it very difficult to shift.
