Understanding Your Transmission
Before troubleshooting, it's crucial to understand the type of transmission in your truck. 1999 Dodge Ram 1500s with the 5.9L typically came with either a 4-speed automatic or a manual transmission. This guide will primarily focus on the automatic transmission, as it's more commonly encountered and presents a broader range of potential issues.

Common Transmission Problems in the 1999 Dodge Ram 1500 5.9L
Several issues can plague the transmission in a 1999 Dodge Ram 1500 5.9L 4x4. These include:
1. Shifting Problems:
- Rough shifting: This could indicate low transmission fluid, worn clutches, or problems with the valve body.
- Slipping: A slipping transmission often manifests as a lack of power during acceleration, or the engine revving higher than expected for the vehicle's speed. This can point to low fluid, worn clutches, or internal transmission damage.
- Inability to shift: This severe issue could result from various problems, ranging from electrical faults to complete internal transmission failure.
2. Fluid Leaks:
Transmission fluid leaks are a serious concern. They can lead to low fluid levels, causing overheating and ultimately transmission failure. Inspect the pan, lines, and seals regularly for leaks.
3. Overheating:
Overheating is a symptom, not a problem itself. It signifies an underlying issue, such as low fluid levels, a clogged cooler, or internal problems within the transmission.
4. Electrical Issues:
The transmission relies on various electrical components for proper function. Problems with the shift solenoid, sensors, or wiring can cause a range of shifting problems.
Maintenance for a Longer Transmission Life
Regular maintenance is key to preventing transmission problems.
1. Fluid and Filter Changes:
The most crucial maintenance is regular fluid and filter changes. Consult your owner's manual for the recommended interval, but generally, it's advisable to change the fluid and filter every 30,000-60,000 miles, depending on your driving conditions and usage. Using the correct type of transmission fluid is also paramount.
2. Regular Inspections:
Periodically check the transmission fluid level and condition. The fluid should be clean and bright red; dark or burnt-smelling fluid indicates potential problems.
3. Cooling System:
Ensure the transmission cooler is clean and functioning correctly. A clogged cooler can lead to overheating.
Troubleshooting Steps
If you're experiencing transmission problems, here are some initial troubleshooting steps:
- Check the transmission fluid level: Low fluid is a frequent cause of issues.
- Inspect for leaks: Look for signs of fluid leakage around the transmission pan, lines, and seals.
- Check the fluid condition: Dark, burnt, or contaminated fluid indicates a problem.
- Listen for unusual noises: Grinding, whining, or humming sounds can point to internal transmission problems.
