The Jeep Cherokee XJ is a classic vehicle that gained a dedicated following over the years, and the 2000 model is no exception. Known for its ruggedness and reliability, the 2000 Jeep Cherokee XJ was equipped with a couple of different transmission options, depending on the engine. Understanding the type of transmission in this model can help you better care for the vehicle and appreciate how it operates.
A Look at the Jeep Cherokee XJ 2000
Before diving into the specific transmissions, it’s good to understand the overall design and build of the 2000 Jeep Cherokee XJ. The XJ was introduced in 1984 and ran through 2001, making it one of the longest-running production vehicles for Jeep. Built as a compact SUV, it was praised for its off-road capabilities while still being versatile enough for everyday use. By the time the 2000 model year rolled around, the XJ had been refined to balance power, durability, and performance.
The 2000 Jeep Cherokee XJ came with two engine options:
- 2.5-liter inline-four engine: For those looking for a bit more fuel economy and less power.
- 4.0-liter inline-six engine: A fan favorite due to its strong performance, especially in off-road situations.
The transmission that comes with your XJ depends largely on the engine type.
Transmission Options in the 2000 Jeep Cherokee XJ
For the 2000 Jeep Cherokee XJ, Jeep offered both automatic and manual transmission options, depending on the engine. Here’s a breakdown of the transmissions you might find:
1. AW4 Automatic Transmission
The most common transmission in the 2000 Jeep Cherokee XJ is the AW4 automatic. This four-speed automatic transmission was paired primarily with the 4.0-liter inline-six engine, which was the more popular engine choice.
The AW4 is well-regarded for its durability and smooth shifting. It’s a simple transmission that does its job without fuss, which made it a reliable option for both on-road and off-road driving. Many Jeep enthusiasts love the AW4 because of its longevity and the way it pairs with the powerful 4.0-liter engine. Even with regular maintenance, this transmission has been known to last well over 200,000 miles.
2. AX-15 Manual Transmission
The AX-15 is a five-speed manual transmission that was used in earlier XJ models but was phased out before the 2000 version. However, some earlier models with the 4.0-liter engine had the option of an AX-15 manual transmission. It provided more control over shifting, which off-road drivers appreciated.
While not commonly found in the 2000 model, some manual enthusiasts might still prefer to swap this transmission in or find earlier model years that came equipped with it. The AX-15 is known for its strength, especially in challenging driving conditions.
3. NV3550 Manual Transmission
For the 2000 Jeep Cherokee XJ with the 2.5-liter inline-four engine, the NV3550 manual transmission was available. This five-speed manual transmission is known for its toughness and ability to handle heavy-duty work. Drivers who opted for the manual enjoyed the direct control it offered, especially when tackling off-road adventures.
Like the AW4 automatic, the NV3550 is highly regarded among Jeep fans for its reliability. Though not as popular as the automatic transmission, it’s a strong choice for those who prefer a manual.
Choosing the Right Transmission for Your Jeep Cherokee XJ
If you’re in the market for a used 2000 Jeep Cherokee XJ or if you’re trying to understand more about your own vehicle, the transmission plays a key role in how the vehicle drives and handles. Whether it’s the smooth-shifting AW4 automatic or the hands-on control of the NV3550 manual, each has its advantages.
For daily driving and casual off-roading, the automatic AW4 transmission is a great choice. It takes care of gear shifts smoothly and can handle rough conditions without too much maintenance. On the other hand, if you prefer to control every gear shift and feel connected to the vehicle, the NV3550 manual transmission might be more your style.
Maintenance and Longevity of the Jeep Cherokee XJ Transmission
One of the great things about both the automatic and manual transmissions in the 2000 Jeep Cherokee XJ is their durability. With proper care, both can last a long time. Here are some tips to keep your transmission in good shape:
- Regular fluid changes: Transmission fluid breaks down over time, leading to poor performance and possible damage. For the AW4 automatic, changing the fluid every 30,000 to 60,000 miles is ideal. Manual transmissions like the NV3550 also benefit from periodic fluid changes to keep the gears running smoothly.
- Check for leaks: Transmission fluid leaks can be a common issue with older vehicles. Make sure to check under your Jeep regularly to spot any fluid puddles or drips. Catching a leak early can save you from more serious damage down the road.
- Pay attention to shifting: If you notice any strange sounds, rough shifting, or hesitation when shifting gears, it might be time to have your transmission inspected. These are early signs that something might be wrong, and addressing the issue early can prevent larger problems.
- Off-road use: If you take your Jeep off-road often, make sure to clean the underside of your vehicle. Mud and debris can get stuck in places that could affect the transmission’s cooling ability.
Final Thoughts
The 2000 Jeep Cherokee XJ is a beloved SUV with strong transmission options that can handle a variety of driving conditions. Whether you have the reliable AW4 automatic transmission or prefer the hands-on experience of the NV3550 manual, both options are built to last and perform well. By maintaining your transmission with regular care, your Jeep Cherokee XJ can continue to run smoothly for years to come, no matter where the road—or trail—takes you.
