Why Jeeps Have Two Shifters

Every one of the Jeep’s 30-plus years has been a story of innovation and technological progression. That progression has meant an innovative design of Jeep’s world-class transmission system. 

Jeep offers something no other vehicle can deliver to customers; “more freedom to go where you want when you want.” Jeep adds more than just a new option for you; it enhances freedom through innovative technology that offers more capability and a greater level of comfort on-road and off-road.

Why Do Jeeps Have Two Shifters?

Jeeps were designed to have low and high gears for crawling up steep hills and powering down steep hills, respectively. The engine and transmission are designed so that the transmission would need to shift more often than with a single-speed transmission, so the two shifters minimize gear changes.

In addition, any obstacle that needs to be overcome on off-road terrain or at high altitude also requires more torque, which negatively impacts acceleration and top speed. 

The solution is to have two gears equate to more torque at lower speeds and less torque at higher speeds.

The development of the transmission is a great example of why the design of Jeep is unique. The gear shifters are located on the steering column for easy access while driving in off-roading conditions or when having to shift in an emergency.

Other transmission layouts that only have one gear had Jeep face a challenge because it would have been extremely difficult to switch gears while driving. 

The Jeep intertwines the needs of the consumer and the design of a vehicle.

Versatile Design of Jeep’s Transmission

Jeeps don’t fail in those situations for various reasons, including their short wheelbase, lighter weight, sturdy frame, ultra-flexible suspension, and high-quality knobby tires. 

However, one of the most important factors in successful expeditions is one that isn’t visible from the rig. It is, however, an incredibly well-engineered transmission system that is the vehicle’s performance backbone.

The design of the gears emphasizes on optimal performance in the most difficult on-road or off-road conditions, regardless of whether they are set up manually or automatically.

But how does it all come together?

Probably, the questions you are asking is yourself are, how is this made possible? What is the purpose of each option? What is the best way to use the gears? 

The Basics of Jeep’s Off-Road System

In general, Jeeps have a dual transfer case, which means a second case is situated at the back of the gearbox case and transfers torque to either the rear differential or both the front and rear differentials at the same time.

Jeep’s Permanent 4×4 (4WD)

A mode in which 4WD is always active and the driver can go safely and securely on any surface. The driver can confidently maneuver in all road conditions. 

To rotate both drive-shafts at a different speed, a central differential or a clutch is needed.

Jeep’s AWD (All-Wheel-Drive) 

Like the full-time 4WD, this mode powers all four wheels and may be used full-time on all terrain. As opposed to 4WD, AWD vehicles don’t have a “4-low” mode. 

AWD vehicles are underperform compared to full-time 4WD vehicles because of the lack of “low range,” but they perform admirably on smooth roads.

Jeep’s Part-Time 4WD

This configuration works in the same way as a 2WD car. The difference between part-time 4WD and full-time 4WD is that part-time 4WD does not use a central differential. 

Instead, both driveshafts are locked. It’s only utilized while traveling off-road or in difficult road conditions. 

However, if you employ part-time 4WD frequently, you may encounter driveline noise or binding, leading to overheating and premature part failure. 

As a result, a driver should use the vehicle’s two-wheel-drive mode when driving in normal conditions.

Jeep’s On-Demand 4WD

During normal driving conditions, this configuration runs predominantly in two-wheel drive. 4WD is automatically engaged in smooth or slippery conditions, and the motion is transmitted to the other axle.

Application and Relevance of Jeep’s Different Systems

Because there are various gear shifts and terrains that to consider, here’s a helpful and broadly accurate guiding principle that you need to remember:

2 Hi (2H) 

In dry terrains, this mode is for regular driving. Nothing extra is required under ordinary circumstances.

4 Hi (4H) 

4H is the position to use when traveling at normal speeds but needs a little more traction, in rough, loose and slippery, roads. On slick roads, the front tires will increase traction to improve your Jeep’s stability.

4 Lo (4L) 

You should use this position when you require optimal traction and power when driving slowly, on rough ground, deep muck, inclined ground, or declines, and you should utilize this position. 

The lower gear ratio engages all your wheels in low range, resulting in a slower road speed and more torque. This position improves engine braking and makes it easier to drive your car.

Can a Jeep be in Motion When Changing Gears? 

To put it succinctly, yes. The longer response is:

Changing From 2H to 4H Mode

To utilize the 4WD when the road is slippery or slack, carefully and firmly move the lever back in one position. This shift will successfully change your status to 4 Hi.

Changing From 4H to 4L Mode

Slow down to 2-3 mph for optimal traction and want to shift into 4L. While the vehicle is still moving, gradually engage the neutral and pull the lever back all the way. Replace the gears in your Jeep, and you’re ready to go.

Part-Time 4 Wheel Drive means that the power only goes to the back wheels when driving on the road. Part-time mode is merely for efficiency’s sake, as it isn’t necessary to provide traction to all four wheels during normal driving.

The conventional manual gearbox shift lever works in the same way as any other manual transmission car. 

To retain traction on loose or slippery surfaces when the Jeep is moved off the road, power must be transmitted uniformly to all four wheels.

The second gear lever is used to shift from two-wheel drive to four-wheel drive. This shift is related to what is known as a “Transfer Case.” 

The Transfer Case is nothing more than a second gearbox with two driving shafts protruding from it. The rear axle is served by one driving shaft, while the front axle is served by the other.

You continue to use the standard gearbox on the Transfer Case in all gear options. However, depending on which gear is selected on the Transfer Case, the vehicle drives differently.

“2H” stands for “normal 2WD road use.”

4WD off-road use or scenarios requiring extra traction, such as dirt roads, tracks, muddy or snowy weather, are designated as “4H.” The “H” stands for High Range, which is the manual gearbox’s standard gearing ratio.

“4L” refers to more extreme 4WD off-road conditions, such as steep hills, very uneven trails, and so on. 

The “L” stands for Low Range, which reduces the gear ratios of the regular gearbox, causing the car to drive substantially slower in every gear. As a result, the engine can rev higher while the wheels slow down, resulting in more torque being produced to navigate difficult situations without spinning the wheels.

The transfer case is connected to the conventional gearbox at the back. It only has two driveshafts rather than the one drive shaft found in a typical rear-wheel-drive vehicle.


Once you’ve mastered gearing, you can start tinkering with certain factory settings. A minor change in tire size can have a significant effect. 

You need to fully understand the fundamentals of gearboxes, transfer cases, and gear locations, to enjoy and benefit fully from your Jeep regardless of terrain or road conditions.

These are other reasons why Jeeps will give you the value for your money:
