What Transmission Is In A 2014 Jeep Wrangler
The 2014 Jeep Wrangler has a reputation for off-road adventure and strong, classic style. But what sits beneath the hood can impact the driving experience just as much as its look.
One key part is the transmission—the system that sends power from the engine to the wheels. Many buyers and owners want to know: what transmission does the 2014 Jeep Wrangler use, and how does it affect performance, reliability, and driving feel?
This article breaks down the details, including the transmission types, gear ratios, strengths and weaknesses, and even how these transmissions compare to other similar SUVs. Whether you plan to buy, maintain, or just want to understand your Wrangler better, you’ll find clear answers here.
Transmission Types In The 2014 Jeep Wrangler
The 2014 Jeep Wrangler came with two main transmission options. Each has its own benefits and fits different driving styles.
6-speed Manual Transmission (nsg370)
Many Jeep fans love the 6-speed manual transmission. The official code for this unit is NSG370. It comes standard on most 2014 Wrangler trims, including both Sport and Rubicon models.
- Gear ratios: 1st (4.46), 2nd (2.61), 3rd (1.72), 4th (1.25), 5th (1.00), 6th (0.84), Reverse (4.06)
- Clutch: Single, dry plate
- Fluid type: Mopar Manual Transmission Lubricant
This manual transmission is made by Mercedes-Benz and is known for its direct feel and simple construction. It’s popular with off-roaders who want more control on rocky or muddy trails.
5-speed Automatic Transmission (w5a580)
The other choice is the 5-speed automatic transmission. Its official code is W5A580, and it’s sourced from Mercedes-Benz as well.
- Gear ratios: 1st (3.59), 2nd (2.19), 3rd (1.41), 4th (1.00), 5th (0.83), Reverse (3.16)
- Fluid type: ATF+4
This automatic is standard on the Sahara trim and optional on others. It’s known for smooth shifting and reliability. It’s a good fit for drivers who spend more time on-road or in city traffic.
Comparing Manual Vs Automatic
Choosing between the manual and automatic comes down to personal preference and how you use your Jeep. Here’s a side-by-side comparison for quick reference:
| Feature | 6-Speed Manual | 5-Speed Automatic |
|---|---|---|
| Gear Count | 6 | 5 |
| Control | Direct, driver-focused | Automatic, easy in traffic |
| Fuel Economy (Combined MPG) | 18 | 18 |
| Towing Capacity (lbs) | 2,000–3,500 | 2,000–3,500 |
| Maintenance Cost | Lower | Higher |
Non-obvious insight: The gear ratios for the manual are closer together, which helps the driver control power better during off-roading. The automatic’s ratios are wider, making for smoother highway driving.
Transmission Performance And Reliability
Both transmissions are well-regarded, but each has unique strengths and some weaknesses.
- Manual (NSG370): Known for durability, but the clutch can wear out if not used correctly. Some drivers report “notchy” shifts in cold weather.
- Automatic (W5A580): Praised for reliability and smoothness. However, regular fluid changes are important for long life.
A common mistake is neglecting transmission fluid service. Both types need fluid changes manuals every 60,000 miles, automatics every 60,000 to 100,000 miles for best results.
Transmission And Engine Pairing
All 2014 Jeep Wrangler models are powered by the 3.6L Pentastar V6 engine. This engine delivers:
- 285 horsepower
- 260 lb-ft of torque
Both the manual and automatic transmissions pair with this engine. The result is a flexible SUV that can handle city streets or rough trails.
Here is how the pairing affects driving:
| Transmission | 0-60 mph Time (sec) | Best Use |
|---|---|---|
| Manual | 7.1 | Off-road, sporty driving |
| Automatic | 7.7 | City, daily commute |
Off-roading And Transmission Choice
Many people buy the Wrangler for off-roading. Here’s how each transmission works for trail driving:
- Manual: Lets you pick gears for steep climbs or descents. It’s easier to “crawl” over rocks.
- Automatic: Less likely to stall. Good for sand, mud, and water crossings.
Advanced tip: If you plan to add larger tires or change gear ratios, the manual may need a heavier clutch. The automatic usually handles upgrades with less stress.
How The 2014 Wrangler Compares To Other Suvs
In 2014, few SUVs offered a manual transmission. The Jeep Wrangler stood out for giving buyers a choice. Here’s a quick look:
| Model | Manual Option | Automatic Option |
|---|---|---|
| Jeep Wrangler | Yes | Yes |
| Toyota FJ Cruiser | Yes (4×4 only) | Yes |
| Ford Explorer | No | Yes |
| Nissan Xterra | Yes | Yes |
This flexibility is one reason the Wrangler remains popular with off-roaders and collectors.
Maintenance Tips And Common Issues
To keep your 2014 Jeep Wrangler’s transmission healthy:
- Change fluid on time—don’t trust “lifetime fill” claims.
- Listen for odd noises: Grinding or whining can mean low fluid or worn parts.
- Check for leaks: Especially after off-road trips.
- Use correct fluid: Wrong type can damage the transmission.
A rare but known problem is the manual’s clutch safety switch failing, which can prevent starting. For the automatic, overheating can happen if towing in hot weather without extra cooling.
