Automatic Transmission In Jeep Cherokee Xj 2000
The 2000 XJ Cherokee uses the AW4 automatic transmission. This four-speed transmission is known for reliability and smooth shifting. It was used in most XJ models from 1987 to 2001, especially those with the 4.0L inline-six engine.
Key Specs
| Transmission | Type | Speeds | Engine Compatibility | Torque Capacity |
|---|---|---|---|---|
| AW4 | Automatic | 4 | 4.0L I6 | ~330 Nm |
| AX4/AX5 | Manual | 4/5 | 2.5L I4 | ~210 Nm |
| Other Jeep (JK) | Automatic | 4/5 | Varies | ~340 Nm |
The AW4 is different from the transmissions used in JK, JL, TJ, and other Jeep models. While the XJ gets the AW4, newer models like the JK and JL often have five or six-speed automatics.
Aw4 Features
- Overdrive gear for better fuel economy
- Hydraulic control for smooth shifting
- Durable design for off-road use
- Separate transmission cooler for temperature control
Most XJ Cherokees with the 4. 0L engine received the AW4. Some base trims with the 2. 5L engine used the AX4/AX5 manual transmission.
Trim And Engine Compatibility
The XJ’s automatic transmission is tied closely to the engine type and trim level.
- Sport, Classic, Limited: Usually 4.0L with AW4 automatic
- SE: Often 2.5L with manual, rarely AW4
- Country: 4.0L with AW4 standard
If you’re searching for a used XJ, check the VIN or sticker under the hood to confirm the engine and transmission combo. The AW4 is not used in models with the smaller 2. 5L engine.
Compatibility Table
| Trim | Engine | Transmission |
|---|---|---|
| Sport | 4.0L I6 | AW4 Automatic |
| SE | 2.5L I4 | AX5 Manual |
| Limited | 4.0L I6 | AW4 Automatic |
| Classic | 4.0L I6 | AW4 Automatic |
| Country | 4.0L I6 | AW4 Automatic |
Towing, Safety, And Performance
The AW4 automatic supports safe towing and strong performance. The XJ’s towing capacity depends on engine and transmission:
- 4.0L AW4: Up to 5,000 lbs (with proper equipment)
- 2.5L manual: Max 2,000 lbs
For safe towing:
- Use a transmission cooler for heavy loads.
- Check fluid levels before trips.
- Avoid towing in overdrive on steep hills.
The AW4’s design protects against overheating and slipping, making it a favorite for off-roading and camping.
Maintenance And Repair Tips
Keeping the AW4 in good shape is easy if you follow these steps:
- Check fluid monthly. Use ATF+3 or Dexron III.
- Change filter and fluid every 30,000 miles.
- Look for leaks around the pan and cooler lines.
- Test shifting—should be smooth, not jerky.
Common Symptoms Of Trouble
- Delayed shifting
- Slipping gears
- Burnt smell
- Fluid leaks
Causes And Diagnosis Steps
- Old or dirty fluid is the most common cause.
- Electrical issues (solenoid or sensor) can cause shifting problems.
- Mechanical wear (bands, clutches) leads to slipping.
Steps to diagnose:
- Check fluid color—should be red, not brown.
- Scan for error codes with a diagnostic tool.
- Inspect for leaks under the vehicle.
If you find burnt fluid, metal shavings, or error codes, visit a mechanic. Repairs range from $300 (solenoids) to $1,500+ (full rebuild).
Aw4 Vs Other Jeep Transmissions
The AW4 is different from automatics in other Jeep models. Here’s a quick comparison:
| Model | Year | Transmission | Speeds | Notes |
|---|---|---|---|---|
| Jeep XJ | 2000 | AW4 | 4 | Best for 4.0L |
| Jeep JK | 2007–2018 | 42RLE/545RFE | 4/5 | Newer, more gears |
| Jeep JL | 2018–Present | 850RE | 8 | Modern, efficient |
| Jeep TJ | 1997–2006 | 32RH/42RLE | 3/4 | Smaller engines |
The AW4 is simpler and easier to repair than newer transmissions. It is also more compatible with XJ upgrades, like lift kits and lockers.
Buying And Compatibility Tips
If you’re buying a replacement AW4 or a used XJ, check:
- Transmission code on the sticker under the hood
- Engine type (AW4 fits only 4.0L)
- Model year (AW4 is 1987–2001)
- Transfer case compatibility (NP231 or NP242)
Avoid mixing AW4 with 2.5L engines—it won’t fit. For more info, see the Jeep Cherokee XJ Wikipedia page.
