The 68RFE transmission, commonly found in Ram trucks, is built for heavy-duty performance, but like any mechanical component, it can experience wear and tear over time. Recognizing the early warning signs of transmission trouble can save you from costly repairs or unexpected breakdowns. Here are the top signs your 68RFE transmission needs attention.
1. Delayed or Slipping Shifts
If you notice delays when shifting gears or experience slipping, where the transmission struggles to stay in gear, this could indicate worn clutch packs or solenoid issues. Slipping shifts often feel like a loss of power or a sudden increase in engine RPMs without corresponding acceleration.
What to Do:
Schedule a transmission diagnostic test to pinpoint the cause. Catching these issues early can prevent further damage.
2. Overheating
Towing heavy loads or driving in hot climates can push the 68RFE beyond its cooling capacity, leading to overheating. Overheated transmissions degrade fluid quality, which accelerates wear and tear.
Signs of Overheating:
- Burning smell coming from under the hood.
- Warning lights on the dashboard, such as the transmission temperature indicator.
What to Do:
Install a transmission cooler or upgrade to high-performance transmission fluid designed to handle extreme temperatures.
3. Leaking Transmission Fluid
Spotting red or brown fluid under your truck is a clear indication of a leak. Transmission fluid leaks can occur due to a damaged pan gasket, seals, or cooler lines.
Why It Matters:
Low fluid levels reduce lubrication and cooling, leading to excessive wear on transmission components.
What to Do:
Inspect the source of the leak and replace worn-out seals or gaskets. Ensure you’re using the correct type of transmission fluid when refilling.
4. Erratic or Harsh Shifting
Abrupt or irregular shifting patterns could mean problems with the transmission’s valve body, sensors, or solenoids. The 68RFE relies on these components for smooth and accurate gear changes, and any malfunction can lead to jerky performance.
What to Do:
A professional scan with a diagnostic tool can help identify specific error codes related to the transmission control module (TCM).
5. Shuddering Under Load
When towing or climbing hills, a shuddering or vibrating sensation can occur due to torque converter issues. This is often caused by degraded lock-up clutch material or insufficient transmission fluid pressure.
Why It’s Serious:
If ignored, a failing torque converter can lead to catastrophic transmission damage.
What to Do:
Consult a transmission specialist for an inspection and consider a torque converter replacement or rebuild.
6. Unusual Noises
Grinding, whining, or clunking noises from the transmission are never a good sign. These sounds may indicate worn gears, a failing pump, or insufficient fluid levels.
Common Noises and Their Causes:
- Whining: Fluid issues or failing pump.
- Grinding: Worn gears or synchronizer issues.
- Clunking: Loose or damaged internal components.
What to Do:
Have a mechanic inspect the transmission to identify and address the root cause of the noise.
7. Check Engine Light
Modern vehicles, including those with the 68RFE transmission , are equipped with sensors that detect irregularities. If the check engine light comes on, it could point to a transmission-related issue, such as a solenoid failure or overheating.
What to Do:
Use an OBD-II scanner to retrieve the error codes. Transmission-related codes (e.g., P0700) should be addressed promptly to avoid worsening the problem.
8. Poor Towing Performance
If your truck struggles to tow loads it previously handled with ease, it could be a sign of transmission wear. Loss of torque, slipping, or overheating are common culprits when towing performance declines.
What to Do:
Upgrade components such as the valve body, torque converter, or clutch packs to improve durability and handling for heavy loads.
9. Reduced Fuel Efficiency
A failing transmission can negatively affect fuel efficiency, as the engine works harder to compensate for improper gear shifts or torque converter issues.
Why It Happens:
A slipping transmission or malfunctioning torque converter reduces energy transfer efficiency, leading to increased fuel consumption.
What to Do:
Addressing the root cause, such as worn internal components, can restore proper fuel efficiency.
10. Metal Shavings in Transmission Fluid
Routine fluid changes are essential for maintaining a healthy 68RFE transmission. If you find metal shavings in the fluid during maintenance, it indicates internal wear.
What It Means:
Metal particles typically come from worn gears, bearings, or clutches and signal that the transmission is breaking down internally.
What to Do:
Flush the system and consult a transmission expert to determine whether a rebuild or replacement is necessary.
Preventative Measures to Extend Your 68RFE’s Lifespan
- Regular Maintenance: Stick to the recommended fluid change intervals and use high-quality transmission fluid.
- Install a Transmission Cooler: Prevent overheating, especially if you frequently tow heavy loads.
- Upgrade Key Components: Consider aftermarket upgrades like reinforced valve bodies or heavy-duty torque converters for improved reliability.
- Drive Smart: Avoid aggressive driving habits, such as hard acceleration or abrupt gear changes, which can strain the transmission.
Final Thoughts
The 68RFE transmission is a reliable unit, but like any mechanical system, it needs proper care to perform at its best. By recognizing these warning signs early and taking the appropriate action, you can avoid costly repairs and keep your truck running smoothly. If you’re unsure about the severity of an issue, don’t hesitate to consult a professional transmission technician.
