Today on the channel we take a look at the core of our Jeep Wrangler JL EcoDiesel - the 4WD system. Lever shift transfer cases are hard to come by in 2021, the Jeep Wrangler is one of the only production vehicles with a manual shifter for the 4WD. As you may know, this causes some confusion for people that are new to four wheel drive or all wheel drive vehicles or those that are used to a knob shifter. Don't worry, you will come to love the manual transfer case in your JL, and we will teach you everything you need to know about it and then some!

Thank you so much for this video. You gave a very thorough basic understanding for engaging 4 high to 4 low crawling at 2 - 5 mph. Even better you gave a description that we should stop the vehicle and have it in neutral from shifting to 4 high to 4 low.
Perfect explanations… WITH CONTEXT. That made all the difference for me. Thank you.
I've owned a JK since 2016 and learned a few things in this video. Thank you so much.
Very informative. Needed the difference between 4WD vs AWD. Thanks!
Just got a wrangler and this video was very helpful. Thank you very much for explaining it simple enough for me to understand and remember all the info easily 👍🏼
🤙🏻
Thank you for the information, we just bought a jeep gladiator and you were very detailed
Owners manual says 2H to 4H can be done up to 45mph. Recommend everyone become familiar with your vehicle's operating manual. Good video.
@dieseJL You can order Wranglers and Gladiators with Auto 4 High. E.g., in addition to regular 4H and 4L, there is also a 4H Auto setting on the lever. So it has 2H-4HAuto-4H-N-4L. You can leave it in 4H-Auto all the time, even on-road. In that setting, the computer will engage 4H when it senses there rear wheels slipping.
In snowy Vermont right now and using jeep. Thanks for all the information
Thanks for making this video, as a new '21 JL owner this is very informative!
Thanks for watching 😎
Excellent, thanks buddy, I learned something today. Jeep Life.
🤙🏻🤙🏻
Thanks for doing this video, great information.
1:55 and that eco-diesel just sounds sick plowing through that snow!
The diesel sounds from it just continue to amaze me... no intake, no exhaust, pure sound 🤟🏻
luv diesel wranglers and hemi as well. both are the best.
Double yoke the front axle at the wheel would get rid of alot of the steering jerking and a torsion diff in the rear would get you three tires spinging. Ultimate 4x4
As an owner I have to say this this is a beast! 20 rolling on 37s getting 23 mpg Pure absolute pleasure to drive. Great video info.
With a diesel?
Thanks for the info. I will be taking my gladiator for a spin.
My wife and I got a 2013 Jeep JK Sport S 5 speed auto 2 door back in 2016, just paid it off. So I got myself a 2020 Jeep JL Sport 6 speed manual 2 door, man the fuel economy is such a difference! Get way better mileage on the JL. We kept the JK so 2 jeeps to offroad together now ahahah
Wonderful video man..! Now I know better my Rubicon and feel less guilty for spending that much money 🙈 thank you very much
Very helpful video. Thanks
Excellent information sir...
Beautiful home......btw...🙂🗽 Ordered my first Jeep last week they say 6 weeks....excited....I got the Wrangler with the High Altitude package with sky touch. Can't wait.👀
Thanks, it’s my parents 🤣
@702FXR got my black antenna in hand. ...🙃
Great video, awesome information sharing!
Thanks!!
Helpful. Thanks!
Awesome vid!!
Every time I watch a new video with the ecodiesel, or a Gladiator.. It makes me so damn eager to get mine.. lol. Soon.. soon.
Then you can go find 14” of snow 😎😎
@@dieseJL you’re gonna jinx me! Lol.. I’m hoping we don’t have any snow by the time I get it, I want it to be warm enough to go topless!
Snow is ok in a Jeep though 😬
@@dieseJL very true!
Great video. I would have added a section on not to engage 4wd on dry pavement roads. Someone is going play around not familiar with using 4wd, bind and have a bad day.
A question in my mind--does the Traction Control help or hurt in the snow like you're driving? I have an '18 JLUR w/3.6L gas engine. In 4-LO the TCS turns itself off, but not in 4-HI. But if I hold down the TCS button for about 5 seconds, it goes off and stays that way. So your opinion here--on surfaces like snow or sand, and in 4-HI, is TCS helping or hurting? I've heard it might be hurting, as the system actually applies braking to a spinning wheel. So, enough of that and there's a power-loss going on? Great video, love learning about the new systems!
The Jeep web site FAQ and manual says top speed that you can shift from 2H to 4H is 55MPH. Of course if you are going 55MPH you probably don't need to be in 4H in the first place. Top speed for 4L is 25MPH.
great channel. Gave you a sub. I am looking at a new 2021 willys now...trying to decide.
Buy it!
@@dieseJL Wrangler UNLIMITED WILLYS SPORT 4X4 Sport Utility-Snazzberry...lol my wife loves the color.
Hey Nice work.
What about brake locking differential or torque vectoring... Can you go over that?
Nice ride super stock!
The 2021 Gladiator owners manual states the preferred shifting speed would be 0 to 45 mph. I remember this also was correct in my 2013 Sahara. Diesels could be different. Thanks for another great video and where in Michigan are you with all that snow in March? Here on the Ohio Michigan border we've been having 70 degree weather and our 20 inches are long gone. ❄🎉
That sounds about right, one time we tried to grab 4HI about 40 though and she wasn't happy This was filmed in Mid-Michigan, end of February. We're a few weeks out on videos....
@@dieseJL that's her baby you are messing with. Proud Jeep owners are like that. She's a keeper if she's a Jeeper. Go Jeep!
I was talking the Jeep 🤣🤣 But 100000% right 💀
Actually the slower the better and easier going from 2wd to 4wd low. 45 mph is the maximum.
Great video very well explained. Why does my JL have 4H Auto and 4H Part Time and other JLs do not.
I think that 4H Auto comes standard on the Sahara only
So that we don't have to teach you how to do it Manually. It does it for you when it feels you slipping instead of us or you doing it manually.
best road car🙂
I just purchased a Wrangler JL Unlimited Sport, very pleased with the 4x4, solid drive axles is what appealed to me. What about locking diff's? That's only available for the Rubicon?
Locking diffs are only on the Rubicon I think, but all JL's have the BLD system wich works extremely well
Perfect 👍🏻
The manual and Mopar video says to shift to 4L while moving between 2-3mph with shifter in neutral. I've done it and it clunks hard as hell...
You can shift easily from 2H to 4H on the freeway, just take your foot off the accelerator. When on the freeway on a long road trip in winter at times you have to activate four wheel drive when you are hitting a snow covered area.
I'd disagree. wheels spinning to provide forward propulsion is different than hitting a snow covered area. You need good tires when you hit that snow covered area. AWD or 4x4 doesn't help you maintain control when hitting a slick spot.
@@mikethompson7406 Ever heard of traction control which takes care of that?
The manual says not to engage/disengage 4wd over 50mph.
@@mikerobinson8734 it may say so. I just shared my experience with you of simply engaging 4H on the freeway while letting go of the accelerator to avoid putting stress on the driveline. The shift is very smooth. Please do whatever suits you.
@@mikethompson7406 a Wrangler Rubicon has 285-wide BF Goodrich All Terrain T/A KO2 tires, and I love the performance of those, both off-road and on-road.
I love my 2021 ecodiesel Willys so far. Do you have any plans to get the cold air intake from AFE or the filter back muffler delete from AFE ? I think magnaflow has a muffler delete too
Honestly it’s kind of loud enough already... maybe when it’s more or a toy I would like to mess around with it but for now I think we’ll leave it as is.
Glad you touched on turning in 4H on pavement. But would like to know will it do the same city driving with snow covered roads? Example not going super fast but need to turn at a stop sign with the road slushed or snow covered.
It depends on the surface I guess. Even if there’s snow on the ground and you’re in 4WD trying to make a sharp turn it will still feel a little stubborn compared to an AWD or Grand Cherokee. I’m talking like sharp turns in a parking lot though, you won’t notice it just like turning left or right on the road. The point I’m trying to make is that this is just normal. They’re not bad to drive in 4wd or anything, just don’t expect it to feel like a Quattro.
It could be hard, but the sharper the turn the harder, one tire is turning faster than the other is why it does that, but if you're on a slippery surface like snow, you shouldn't notice it too much. Only prevalent on surfaced that have a lot of grip typically. Even dirt you can typically turn fine in.
Thank you thank you. Owned my 2019 Wrangler for 2 years never had to use 4wd in Hawaii...well now im in WA and couldn't figure it out today. Driving around in 2wd and couldn't make it up a slushy icy hill while everyone else driving past me. Quite embarrassing. Could not figure out out to shift the transfer case - watching KZhead videos sitting in the middle of the road. Will try this tomorrow
Why else would you have a Wrangler
Great video, a question, I just got a 2021 WILLYS manual transmission, to I have to use clutch to switch from 2H to 4H? You are right about 4WD after having 2 WRX I keep my Willy’s
I bet if you were idling in a lower gear you could rip it into 4H, otherwise yeah just a slow roll with the clutch in will be your best bet to go from 2H to 4H. Make sure you’re stopped to go to 4LO…
What about your lockers? Could you show a video on that?
Only needed if you're rock crawling or if you're still stuck even in 4 low. Locking front and rear gives equal speed and torque to ALL your tires, instead of one or two.
"if you get stuck in your Subaru..." what?! I've yet to get stuck and I've TRIED! :D However, I also ordered a '22 Wrangler as my first ever Jeep and am trading in my lifted '18 Outback because the Jeep is better. I'd take a Subaru anyday for a daily driver in the snow but that's not my intention. My struts are all leaking at under 60k because I do Jeep things in my Outback. haha
I have an unlimited 2021. Just to ask a quick question should i be in motion going from 4WD High to neutral to low or should i be at a complete stop? Sorry I am very confused on that part
I would say 0-1 mph. The important thing is to NOT FORCE THE LEVER!! To me, it seems a little easier to shift if you’re moving very slowly. Helps everything mesh.
I just got a JL Willys. I have feel like it is pretty hard changing to 4h in Park. I’m used to having a pickup and turning a knob.
It’ll get easier with time!
8:25 The owners manual literally states, “The preferred shifting (2H To 4H Or 4H To 2H) speed would be 0 to 45 mph.”
Mine says 50mph 21’ Jeep JL eco diesel
this is 3.0 eco diesel version?
Recently I got stuck in my 2018 sport s. I was in 2H with a back tire spinning. After a while I got out but never figured out how to engage 4wd from 2H while stuck. Should I have put it in neutral and switched from 2H to 4H while not in motion? Can I engage 4wd while the car is not moving?
You definitely can, I would put the transmission in neutral and just throw it in to 4H. You should shift it to 4H a few times when you don’t need it to get comfortable with it for when you do!
I just traded in my old 2001 TJ for a 2021 Rubicon JL. I'm still learning all the aspects of all the features. Many things I like and some I don't like, but give me a month for it to grow on me. I wonder when Jeep will go to independent suspension on the axels?
Are those "Off-road Pages" only available on the Rubi? My Willys doesn't show that on the UConnect.
I have a 2021 Sport with the 7" screen. I don't have the off road pages either. So, it may be that all Rubicons have an 8" screen with the pages or if you got the 8" screen on a Willys or Sport you get the pages. Do you have the 8" screen?
perhaps i would have included a locking differential discussion in the video...many, if not most, jeep buyers don't have one in the rear....rubicon owners get one, regardless of powertrain option, but so do diesel powertrain buyers, regardless of trim level......willys owners get one too, regardless of powertrain option....but for many owners, they don't have one....makes a difference even on wet roads under hard acceleration, especially when turning......let alone off road.....
I’m not knocking the EcoDiesel JL, because I actually want one. Actually almost exactly like yours. My hesitation, however is that the EcoDiesel has not had a stellar track record in the reliability department. I’ve heard this is a “new generation” of it, but I’m still holding back to see if they are actually doing better. Any input on that?
Well... yeah, lots of thoughts 🤣 Diesels get a bad reputation, think 6.4 Powerstroke. But there’s dudes out there that make them work and they’re amazing. Is the EcoDiesel perfect? Probably not but it’s fun and cool and that’s what Jeeps are about. If you want the safest option don’t get one. If you’re looking for power and fun and can live with maintenance and won’t get too upset if at 75k you have to replace something minor then dive in man!
I think this is a Fiat engine, used in Alfas and other Fiat models. Should be rather reliable.
Lockers should never be used on normal road conditions! Damage to drive train can occur…😉
What kind of axles come in the 2023 4xe wrangler sahara
D44HD
This is the only one JL engine (diesel 3.0) without the "4H Auto" option. All the rest starting from Sahara version (2.0, 2.2D, 3.6) have this one for daily use. I drive my 2.0 Sahara in 4H Auto, it works very well, in deep snow also. Does anybody know why ecodiesel does not have this option? To cut costs?
No Rubicon model has the 4H Auto, it's only Sahara. The diesel is no different to the gasoline version. The only exception is the Rubicon 392 V8, which does have 4H Auto.
My 2022 JLR with V-6 etorque has 4H Auto
Does the rubicon come with lockers?
Yes... perhaps another video on that someday 🤔
What is top speed that you can drive a jl on 4 high?
'as fast as road conditions permit' Jeep doesn't really put a rating on it, I don't think there is mechanically one.
hi I see that your fuel ave is 17.5 I bought my rubicon 2020 brand new a month ago , it is still 13.5 :( . any idea ????
Ours is a diesel, I’m guessing you have the 3.6
@@dieseJL no I have the 2.0 L 🥴
Ouch, hang in there?
I would agree with most of what you say, but the Wrangler 4WD is not "better" than Subaru AWD. In fact, the Subura AWD system is entirely based on the Jeep Corporation Quadratrac with viscuous coupling. It's a limited slip differential, not an open transfer case differential. You can't stop them.
Fair, but at the end of the day the Subaru isn’t designed to take 100% of motor torque to the rear wheels. The components are small, and when you’re staring up a mountain or something that matters 🤷🏻♂️
I live in Canada where the roads are covered in snow and ice. I put my rubicon (2021) in 4WH and STILL feel the jeep slipping and sliding. Be in mind the roads where i live have 10-15 foot ditches on both sides of the road, so sliding and losing control is not an option. PLEASE HELP! WHAT AM I DOING WRONG? Should I be in 4L? I need to be able to speed up to 65 km/h to keep with traffic and speed limits. TIA. And YES my tires are original factory and only 7 months old
4 low won’t help, I would try airing down your tires to like 35psi, lower if you feel comfortable with it. Not sure why you feel it sliding, ours feels like a literal tank! Lisa loves driving it in the winter.
Before my rubicon I had a sahara (2014). I don't know what it was, the fact that it was manual and my rubicon is automatic, the tires? I swear I could drive through anything without a worry. But something about the rubicon is different and does not feel as safe to me. Just my opinion from experience. I think I will honestly switch back to sahara when the time comes. Stacked with all the goods of course.
Two suggestions: 1 - Try using your lockers. First try just the rear, then try both. Definitely helps climbing hills in snow. 2 - Tires make a huge difference. If you have mud-terrain tires, switch to all-terrain tires that are rated good for snow. Mud tires just don’t do as well on snow & ice. Good luck!
@@stoney3398 yes so I have the stockk tires that are specific for climbing/mud. Horrible for snow/ice. I'm not climbing snow banks. Just driving down horribly plowed roads. The tires I got with my old sahara were amazing. Way better than stock rubicon tires for canadian roads. I'll give your suggestions a try next winter season thank you.
Command-Trac, shift on the fly. Remember those commercials??? Some people try to yank it in 4H, from dead stop. No good! Shift on fly.

When should you use it? Anytime the road is slippery, contaminated with frozen precipitation, or there is any pooling of water, risking hydroplaning...The Jeep is designed to best operate in 4WD in these conditions.
Yes to All
You sure about the rock-trac in your JL? I thought you cannot get the rock-trac with the ecodiesel. Cheers.
I looked quite a bit, the only literature I can find is that rubicon’s have it 🤷🏻♂️ It’s come up before, can’t really find a definitive answer. Either way with the four low and the 8 speed the crawl ratio is super low.
@@dieseJL I just went of the build for em through jeep.com, either way you're right. It's low enough for anything you'd need
What’is top speed four-wheel-drive high
Faster than you can go when needing it 🤣
I don't get the explanation of the jeep 4wd. Only one wheel in the back and 1 wheel in the front will spin? I thought 4wd meant all 4 wheels have power going to them?
I'm going to try and make a video on this in the future but here is the short - The 4WD system has the ability to apply power to any of the four corners. And it will pretty evenly apply it under normal conditions. However, if you got stuck, the differentials in the front and rear would end up supplying power to the path of least resistance. That would be the tire that is spinning and not moving you forward. The differentials are in axles so that you have better on road manners but they hurt you off-road. So, in the case of the Rubi or other Jeeps they add things like differential lockers, limited slips, etc. to give you the best of both worlds - on road manners and then on demand you can have all four wheels locked in. But, for this video since they are not in most Jeeps, I assumed that both the front and rear differentials or 'open' Like I said, stay tuned.
You'll have all 4 wheels spinning in 4H. Traction Brake locking differential would kick in. Even at diagonal "twister" electronic with abs would get wheels with lesser resistance to spin. I do have 2021 JL Rubicon. I also sell them last 2 decades. There is a model that is more suitable for every day use with 4wd Auto. From 2wd to 4wd auto you can shift at any speed "it will act as AWD with steroids" it comes also with off road plus button. That allows you to lock rear locker and drive it in 4h up to 80km/h with rear locker on.
How fast can you go in 4H?
Fast as you want!
Right ?
how fast can you go in 4 high?
'as fast as road conditions permit' Jeep doesn't really put a rating on it, I don't think there is mechanically one.
I would say 55 max. If the road conditions are good enough to go faster than that you should not need 4 wheel drive anyway.
I've always wondered, how hard is it on the drivetrain to go on a mostly dry road, gentle turns in 4 hi? I never did in my XJ but wanted to in case of unexpected ice patches etc
According to the Owner's Manual, you shift to 4-Low while rolling at 2-3 mph with the transmission in Neutral; once engaged, shift back to Drive and enjoy off-roading. 😎
Yes. The bears need to mesh. Knowing that, the average person should understand it. The problem is people are really that stupid.
More people need to know this.
I'm going to have to disagree with you about the wranglers four wheel drive system being better than a Subaru. If anything I'd say it's on par with the Subaru. My wife's car is a 2020 Subaru Forester sport, and I am in love with her car. You turn traction control off and each wheel gets 25% power. I've done some serious hill climbs, through the last ice storm we had a few weeks back and pretty much every weekend I go hit the local mud pot, I've yet to ever get stuck. The only thing that I dislike about her Subaru Forester sport other than all the damn evil technology in it which wants you to hit your brakes 24/7, even with a lift kit the max tire size you can fit on it is about 29 in, if you want anything over that you need to do some serious body modifications, which annoyingly enough my wife won't let me do. :'( Love the videos keep making them!!!!! ❤️
If you need all tires locked, it is bettter. Subaru’s will end up spinning before power is transferred. This will slow or cause slip. So when you really need it, it’s better. Most stuff, you don’t need it.
Subaru owners are watching this mad as hell and farting up a storm
1 tire spinning in my old 91 s10 blazer in a 1/4 inch of sand...😡🤷
Right? Right? Right? Right? Right? Right? Right? Right?
I think you're confused on how 4 wheel drive works. You described lockers.
He just shoulda said differential instead of axle. Also my Subaru used to throw traction 50/50 front and rear when in snow. Had a ‘15 forester 6m which I drove thru snow plenty of times here in the mtns of nepa.
Not all jeeps...Just Rubicon and Mojave have the true 4WD
All Wranglers (including Saharas & Sports) have always had true 4WD, with the exception of a few years of JKs, 2007-2010 only. The 2WD versions weren’t very popular, though.
Save yourself time. Buy a Tazer and delete all the factory traction control bs if you plan off being offroad.
Maybe a future video 🤷🏻♂️
Oh my God go buy us Suburban
Come back at 35-50k miles lol and then tell Jeep’s fiat area great 😂
Question.. how will that jeep do in the snow when it breaks down at 45k miles and the Subaru drives by it? Lol .. just playing
Lol, Subbies are anything but reliable themselves. And while good on the road with the Subbies really nice AWD system, it will never, no matter what you do to it, ever be on the Wranglers level off the road.
Subaru are oil burners
I own both but in the winter going over donner pass in California i am always in my diesel willys
Rides like crap (solid axles), handles like a tank, gets terrible gas mileage, & is noisy at freeway speeds … love my Jeep JLU. 😁
Still the same and the price much higher
jl= just laughable...jk= justified king!
So many things in this video are incorrect
You can shift into 4H up to 55 mph. When shifting from 4H to 4low you want to be at a slow role of 2-5 mph and then shift into 4l
Lol you clearly never had a Subaru in the snow. It outrun any jeep including a JL learn more about why it stops a tire you might like that! I own both and on snowy days Subaru is the boss!! Keep is cooler.
Your opinion, i take my diesel willys any day
