Automatic Transmissions in the 1998 Jeep Wrangler
AX-15 vs. AW-4
The 1998 Jeep Wrangler offered two main automatic transmission options: the AX-15 and the AW-4. Both provided a different driving experience, each with its own advantages and disadvantages. Understanding the nuances of these transmissions can help you make an informed decision when buying a used Wrangler or if you’re considering a transmission upgrade.
AX-15: The Classic 5-Speed Manual
The AX-15 was a robust 5-speed manual transmission known for its reliability and off-road capability. It was a popular choice for Wrangler owners who valued a more engaging driving experience and the ability to manually select gears for optimal performance in challenging terrain. The AX-15’s durability made it a favorite among Jeep enthusiasts who often pushed their vehicles to their limits.
AW-4: The Smooth Shifting 4-Speed Automatic
The AW-4 was a 4-speed automatic transmission that offered a smoother, more comfortable driving experience compared to the AX-15. While not as rugged as the manual option, it was still capable and reliable for everyday driving. The AW-4 was generally preferred by drivers who prioritized ease of use and a more relaxed driving style.
Transmission Characteristics and Considerations
- Gears: The AX-15 had 5 forward gears, while the AW-4 had 4. This meant the AX-15 offered more precise gear selection and control, especially in off-road situations.
- Torque Converter: The AW-4 utilized a torque converter, which allowed for smoother gear changes and eliminated the need for a clutch pedal. This made it more convenient for drivers who were less familiar with manual transmissions.
- Fuel Economy: The AX-15 often resulted in slightly better fuel economy due to its direct gear connection and lack of a torque converter. However, modern automatic transmissions often offer comparable or even better fuel efficiency.
- Maintenance: Both transmissions were relatively low-maintenance, but the AX-15 required periodic clutch adjustments and fluid changes. The AW-4 typically needed fewer adjustments but might require more frequent fluid flushes.
Choosing the Right Transmission
The best transmission for a 1998 Jeep Wrangler depends on your individual driving needs and preferences. Consider the following factors when making your decision:
- Off-Road Use: If you frequently drive off-road, the AX-15’s 5-speed manual and superior low-range gearing may be a better choice.
- Daily Driving: For daily commuting or highway driving, the AW-4’s automatic convenience and smoother shifting might be more desirable.
- Experience Level: Manual transmissions require more skill and practice to operate. If you’re new to driving stick, the AW-4’s automatic operation could be easier to handle.
