A manual transmission is just a solid piece of engineering that doesn't want to break. It doesn't care what angle you are. It has compression braking that automatics can't touch, and when you are driving it you feel connected to your Jeep. It is a more immersive driving experience.
With a manual you only worry if it shifts and does it go. A slipping clutch, bad synchros, grinding bearings, or even loss of fluid will rarely if ever prevent you from getting home. You can pour engine oil into your manual tranny, pound wooden wedges between your clutch and flywheel, or just grind gears with no disengagement, and still have no troubles finding your way home. With an auto, you have to call a tow truck. It's really as simple as that. A manual transmission will (almost) always get you home. On that same note, if your battery dies for any reason an automatic transmission will need a jump start to get running, whereas a manual tranny just needs a push start.
The automatic on the other hand won't stall when you are traversing a tricky patch of rocks, makes it really easy to get into off-roading with less experience, and can't be beat in on highway rush hour traffic. I prefer manual transmissions for wheeling. That said, I do own vehicles with automatic transmissions.
My Ford F350 has an auto. Because I don't want to work a clutch in stop-and-go traffic or worry about stalling when backing my boat up my snaking, inclined driveway. My Cherokee, YJ, and 47 Willys all had autos, but at some point in time I found myself thinking, 'I'm gonna put a manual transmission in this thing.'
Conversely, I've never once thought, 'Hey, this Jeep needs an automatic!' While driving one of my manual-transmission Jeeps. I just like to feel connected to my Jeep, and I feel an automatic takes that away. While off-roading in an automatic, you have to worry about torque converter flash rpm, stall rpm, shift point rpm and vehicle speed, vacuum and cooling lines, tranny pan leaks, overheating, plugged coolers, uncovered sump pickups, burned fluid, and so much else. In an emergency maneuver you have to worry about how quickly you can toggle the shifter into Neutral or Reverse and then whether or not the tranny will be sucking air or if it'll actually grab and save your bacon before you roll down a tall cliff and die.
2018 Jeep Rubicon Owners Manual
Sure, autos can shift faster than a manual, but we're talking off-roading in Jeeps here, not drag racing. Manual transmissions can improve fuel economy, they generally last longer, require less maintenance, create less heat, sap less horsepower, and are typically less expensive and easier to repair and rebuild than their automatic counterparts.
I once sunk a manual transmission into a swamp and it still worked for quite a while, although it was filled with water. An automatic instantly stops working when the oil becomes contaminated. On steep hills the oil pickup on many automatics will starve for oil, halting forward movement. As long as the gears and bearings get a splash of oil now and then, the manual transmission can run upside down all day long if need be. Again, choosing a should still be primarily based on preference.
I'm sure you aren't going to purposely run upside down, but if you don't plan to get in potential rollover situations or do 90% of your driving on the street, perhaps an automatic is best for you. Just remember, you can't undo your decision when you are hanging upside down on the trail. One of the common debates when choosing a Jeep is choosing between an automatic or manual transmission. In addition to the overall on-road affect each has, the concern also revolves around how each is suited when. Automatic Transmission: Automatic transmissions allows for a very relaxed driving experience while off-road and especially while towing in difficult terrain. Allowing you to concentrate on the obstacles ahead, without the need to engage a clutch. In addition, automatic transmissions provide you with the ability to maintain a slow steady crawling speed, needed for precise adjustments while towing in difficult terrain.
Nonetheless, automatic transmissions do have some pro’s and con’s: Pro:. Easier to navigate while on the trail. Easier to maintain a steady speed/acceleration. Easier to make small incremental movements Con:. Harder to adjust delivery of power to the wheels in certain conditions.
More complex of a system to maintain/repair Manual Transmission: a manual transmission is easier to regulate power delivery to the wheels, providing you with the ability to recover or get out of difficult situations easier. It is also a much simpler and straight forward drive train to maintain and repair. Nonetheless, manual transmissions also have some pro’s and con’s: Pro:.
Easier to make small incremental movements/adjustments. Easier system to repair and maintain Con:. Harder and more tiring system to drive in slower speeds, involves a good amount of clutch engagement. Harder to maintain a steady gradual level of speed/power, making precise movements difficult. Automatic and manual transmissions handle slightly different. An automatic transmission utilizes torque converters to achieve a greater range of gearing, allowing it bounce around to different gears more effortlessly, unlike manual transmissions that utilizes a set gear ratio and require you to manually engage/disengage them at appropriate intervals. Both transmissions can achieve the same level of gearing at a particular point in the trail, but they have different advantages/disadvantages.
An automatic transmission is easier to use on the trail and the torque converter does a great job of selecting the proper gear for the particular demand. However, that transferring of gears comes at a price, which is heat build-up and eventually causes slippage if overly used. A manual transmission has a set gear ratio that is less problematic but requires more attention when engaging. In addition, since it’s a more set ratio, it requires more attention when setting up, because it will have a dramatic effect on the shifting points, which could be tiring while on the trail. When properly selecting, you can manage most of the trail runs with minimal amount of shifting, ensuring less strain/demand on the transmission and equally important on your knee.
Automatic transmission drawbacks: Automatic transmissions offer a great ease of use both on and off-road. Seamlessly transferring gears automatically depending the specific conditions and demands. The process is great but eliminates the choice of gearing from the driver, relying more on the transmission to make the choice. This relinquishing of power is subjective but could also lead to overheating if the Jeep is on a long, burdening trail. The overheating could then lead to gear slippage and serious damage if overlooked. Manual transmission drawbacks: Manual transmissions allow you to fully engage yourself with the driving experience and provide a great level of feedback of the demands placed on the Jeep and giving you the option to select the proper gear for the particular situation.
This level of choice could be problematic and tiring if you’re on a difficult and long trail. Often times you’ll need a high level of finesse and control to maneuver slowly out of an obstacle. An improper shifting of gears could lead to miss-calculated level of movement that causes damage to the Jeep.
In addition, manual transmissions have a set level of gearing with specific shifting points that might work well on the trail, but could be tiring on the road in everyday use.

Share. Facebook. Tweet. Pinterest. Email South Island, New Zealand: It’s day two of a two-and-a-half-day overland adventure. We’re driving through some of the world’s most mind-melting scenery, taking the slow, hard routes, crossing streams as often as we can and trying to touch pavement as infrequently as possible.
At this particular point in the trek, we’re creeping through someone’s multi-thousand-acre sheep station (like a cattle ranch but for, yep, sheep) on the outskirts of. To the right, towering above us, is a glacier-capped peak, which sends the occasional blast of icy air to us in the valley below. On the left is a gully rendered impassible by boulders.
The rock field where we’re going to test the new Jeep’s scrambling abilities is, I’m figuring, somewhere up ahead. I figure wrong. The boulder-choked gully is the rock field. Next thing I know, we’re disconnecting the sway bars and locking the differentials (or pressing the button and toggling the switch to accomplish the same), and our four-truck caravan is scrambling up and over the obstacles like a little herd of mountain goats. Then we cruise back down and do it over and over again until lunch. Spotters take a lot of the stress out of the process, as does the wheel angle indicator in the instrument cluster (one of many toys new for 2018).
Ultimately, though, it’s that time-tested four-wheeler formula - torque channeled through the transfer case’s 4.0:1 low range to a pair of electronically locked Dana 44 live axles, then onward to the meaty 33-inch BF Goodrich rubber at all four corners - that makes it seem so easy. The point of the exercise is clear: The all-new Wrangler is capable of handling anything you can imagine throwing at it - and a good deal you can’t. You could have guessed as much from a glance at the specs.
In every meaningful way, from approach and departure angles to ground clearance to fording depth, it’s an upgrade over its rugged predecessor. But when you’re offered the opportunity to try it out for yourself in Middle Earth, you go.
New Wranglers don’t happen very often, only about every decade or so (the outgoing Wrangler JK was introduced for the 2007 model year). Like a comet vintage, the coming of a new take on the Ur-Jeep merits celebration - hence the antipodean trekking party - but enthusiasts are right to be a touch apprehensive about the whole ordeal.
The Wrangler is the spiritual and direct successor to the legendary CJs, and thus the war hero Willys MB; though no vehicle can afford to remain unchanged forever, this thing carries on its sport bar-equipped back an unusually weighty heritage. Anyone tasked with doing a ground-up redesign ought to tread very, very carefully. The execution With all that in mind, it’s hardly surprising how familiar the whole package looks and feels when viewed in isolation.
As it happens, though, another small herd of Jeeps, all JKs, is there to serve as support vehicles. They look dangerously close to dated next to the fresh JLs.
It isn’t any one thing; the new trucks benefit from a series of little styling refinements - a side character line here, a deleted bit of fussy plastic trim there - that add up to a big overall impact. This is, as I learn, something you can say about the whole vehicle. The powertrain reads like old news, but only for the base truck.
The 3.6-liter Pentastar V6 is standard, even on the top-level Rubicon, with 285 hp and 260 lb-ft of torque. It remains a serviceable if uninspiring motor; in this new application, it hasn’t picked up any of the low-end grunt that it could so badly use. Once I learn to ignore its high-rpm wail while cruising in low range - something I have to relearn every time I’m driving a Wrangler in low - it works well enough. Would the new, optional turbocharged 2.0-liter inline-four’s ample torque (295 lb-ft from 3,000 rpm) make it easier to creep around with a manual?
It’s impossible to say because the six-speed is only available on the V6. Every other Wrangler will, at this point, get an eight-speed automatic. (Diesel and plug-in hybrid variants are in the works. Like the turbo I4, these should provide plenty of accessible torque; it will be interesting to see how these are received - especially that hybrid - and how they play on the trail.) It’s a shame that you can row your own only with the base motor because its action is hugely improved over the JK’s. It’s not a short-throw gearbox by any means, nor should it be, but the vagueness and loose-tooth wiggling when you’re in gear is gone. As with everything else on the truck, from styling to ride, the slack has been pulled out of it; the action is now crisp and pleasant.
There are different schools of thought about whether a manual or an automatic is better for various Wrangler activities (say, mudding versus rock-crawling). It makes for a more engaging and old-school experience, though, and it adds an extra level of challenge to certain maneuvers. Throw thick, peaty mud into the mix, the perfect consistency to pack the treads of those BF Goodrich KO2 All-Terrain tires, and you’re pretty well on your way to understanding how, early in our trip, I find myself stuck on an especially greasy ascent with a steep drop-off a few yards behind me. The funny thing about those pulse-quickening off-road moments is how they unfold so very slowly compared to driving on the track.
It’s the only time someone has to break out the tow strap and the winch. Hey, it had to happen to someone.
And that snafu aside, the JL is demonstrably more capable than the previous model. Designer Mark Allen, driving one of those support JKs, gets hung up on a rise the JLs didn’t sweat. I don’t get the sense that he’s the type to sandbag; sometimes, eight-tenths of an inch of extra ground clearance and 4.5 degrees of extra breakover angle can make all the difference. That said, while driving the JL, there’s no moment of revelation - no big leap forward to smack you upside the head. That this is an all-new vehicle comes across in a series of upgrades and refinements; the boxy body-on-frame attitude is still there, but it feels less crude, more honed. Not a few times I find myself staring at some reimagined component or seemingly minor new feature and thinking, “Why didn’t they do this 10 years ago?” Case in point: The soft top. The Wrangler is fundamentally a convertible; that’s part of its appeal.
Historically, however, the canvas tops have been heavy on the zippers and a total pain to operate under anything other than ideal conditions. Owners have grinned and borne it (or opted for a hard top). The accursed zippers are gone, and the side windows are now attached with a series of channels and retainers. The roof itself has never been easier to operate; even on a four-door Unlimited, I’m able to raise and lower the top in moments. It’s a beautifully engineered piece - only the ragtop on the new bests it when it comes to simplicity. On its own, it’s not revolutionary, but it’s a thoughtful and effective upgrade. I could say the same thing about the reduced turning radius and the increased window area (which makes for a much more open-feeling cabin).
Or the doors, which are easier to pop off and reinstall than ever before thanks to staggered-length hinge pins. Or the windshield, which used to require the removal of 28 bolts to lower but now takes just four (and those bolts are inside the cabin, where rust won’t freeze them in place). Or the fact that Jeep designed the JL with the burgeoning aftermarket in mind - you’ll be able to take off the stock 33-inch tires, bolt on 35-inchers and, with a Mopar 2-inch lift kit, regain full range of suspension travel after spending a few hours wrenching in the driveway. In all likelihood, most buyers won’t take regular advantage of these features. But they should. They’re part of what gives the Wrangler its unique charm, and commendably, Jeep has made them more accessible than ever.
The takeaway There’s an Enzo Ferrari quote, frustratingly difficult to attribute, to the effect of: Jeep is America’s only real sports car. He probably meant that as a dig at Chevrolet’s Corvette, but there’s more truth to that particular chestnut than the snarky Commendatore realized. As with the best old sports cars, Wranglers (like the CJs before them) have always been honest, elemental machines, the fundamentals of their form dictated largely by function. This honesty is palpable the moment you hop in. It’s not your average commuter box; the Wrangler transports you somewhere, at least mentally, before you put it in gear.
As far as sports cars go, it’s one perfectly matched to our national spirit. No one really needs a Wrangler as a daily driver. But this is America! We revel in glorious overkill! “Doomsday Preppers” is part of our cultural legacy; “It’s better to have it and not need it than need it and not have it” might as well be our national motto. We are as much in love of with the idea of what the Wrangler can do as we are with actually doing it.
I’d venture that not every owner of a is a track rat, either. There are two groups of people who will not enjoy the JL. First, you have the crusty arch-purists who think that Jeep lost its way the moment the last CJ-2 rolled down the assembly line; the JL will do little to persuade them otherwise. Conversely, there are those who see the JL’s live axles and aero-flouting two-box design as hopelessly anachronistic. Rather than allowing them to ruin the Wrangler, I will happily point them to any one of the more or less car-like crossovers infesting the lineups of every manufacturer. Jeep included. For the swelling legions of people who do really get the Jeep Thing, though, the JL is just about perfect.
It’s everything great about the previous Wranglers made better: It can do astounding things right from the factory, it is rivaled only by Lego or the AR-15 when it comes to customization potential (, and the aftermarket is just getting revved up), and while our off-road-centric journey didn’t give much of a taste of its on-road manners, it does promise to be more comfortable on pavement and somewhat more livable day-to-day than the JK. This should go without saying, but Jeep absolutely could not afford to mess up here - for its own sake, sure, but also for the sake of all of us who love Jeeps and what Jeeps stand for. So much of the brand’s identity, as well as off-road culture in general, is tied up in this one Toledo, Ohio-built vehicle. They didn’t mess up. The JL is proof that honesty is still the best policy when it comes to the sort of vehicle enthusiasts can really get behind, and it’s a worthy inheritor of 76 years of all-American go-anywhere tradition.
