The 1999 Dodge Durango, a popular SUV of its time, is known for its robust build but, like any vehicle, it has its potential weak points. One area that frequently requires attention is the transmission. This comprehensive guide will delve into common 1999 Dodge Durango transmission problems, troubleshooting steps, repair options, and when replacement becomes necessary.
Understanding Your 1999 Dodge Durango Transmission
Before diving into potential issues, let's briefly cover the types of transmissions found in the 1999 Dodge Durango. This model year typically featured either a four-speed automatic or a five-speed manual transmission, depending on the engine and trim level. The automatic transmission was more common. Knowing which transmission you have is crucial for accurate troubleshooting. Your owner's manual will specify this information.
Common 1999 Dodge Durango Transmission Problems
Several issues plague the transmissions in 1999 Dodge Durangos. These include:
1. Slipping Gears
A common symptom is the transmission slipping or failing to engage gears smoothly. This can manifest as delayed engagement, a feeling of the engine revving without corresponding acceleration, or sudden gear changes. Causes can range from low transmission fluid to worn-out clutches or internal components.
2. Hard Shifting
Rough or harsh shifting is another frequent complaint. This can indicate issues with the valve body, solenoids, or low fluid levels. Hard shifting can worsen over time, potentially leading to more severe transmission problems.
3. Transmission Fluid Leaks
Leaks are a significant concern, as low transmission fluid can lead to overheating, damage to internal components, and eventual transmission failure. Regularly check your transmission fluid level and condition. Look for leaks under the vehicle, paying close attention to the transmission pan and surrounding areas.
4. Overheating
Overheating is a symptom of various problems, including low fluid levels, a clogged transmission cooler, or internal mechanical issues. Overheating can severely damage the transmission.
5. Complete Transmission Failure
In severe cases, the transmission may completely fail, leaving you stranded. This usually occurs after neglecting smaller problems or due to severe internal damage.
Troubleshooting Your 1999 Dodge Durango Transmission
Before considering a repair or replacement, perform these troubleshooting steps:
1. Check Transmission Fluid Level and Condition
This is the first and most important step. Use the dipstick to check the fluid level while the engine is running. The fluid should be bright red; dark, burnt fluid indicates a problem.
2. Inspect for Leaks
Carefully check for leaks around the transmission pan, cooler lines, and seals.
3. Listen for Unusual Noises
Strange noises, such as whining, grinding, or banging, can indicate internal problems requiring professional attention.
Repair vs. Replacement
Repairing a 1999 Dodge Durango transmission is possible, depending on the extent of the damage. Minor issues, like low fluid or a minor leak, might be easily fixable. However, significant internal damage often necessitates a rebuild or replacement.
Factors to consider when deciding between repair and replacement:
- Severity of the damage: Minor issues are usually cheaper to repair.
- Cost of repair vs. replacement: A major rebuild might be as costly as a replacement.
- Age and condition of the vehicle: Replacing the transmission might not be worthwhile in an older vehicle.
- Availability of replacement parts: Finding parts for older vehicles can sometimes be challenging.
