Understanding the 68RFE Transmission
The *68RFE transmission* is a six-speed automatic transmission specifically designed for heavy-duty applications in trucks. It is commonly found in Dodge Ram trucks with Cummins diesel engines. One of the key features of the 68RFE transmission is its ability to handle high torque loads, making it a reliable option for towing and hauling heavy loads.
Additionally, the 68RFE transmission utilizes a sophisticated electronic control system to optimize shifting performance based on driving conditions. This allows for smooth and efficient gear changes, enhancing overall driving experience.
Overall, understanding the inner workings and capabilities of the 68RFE transmission is crucial for truck owners who rely on their vehicles for demanding tasks.
Common Problems with 68RFE Transmission
One common problem with the 68RFE transmission is overheating. This can be caused by a variety of factors, such as towing heavy loads or driving in high temperatures. Overheating can lead to fluid breakdown and internal damage, so it’s important to address this issue promptly.
Another issue that 68RFE owners may encounter is clutch failure. The clutches in the transmission can wear out over time, especially if the vehicle is used for heavy-duty tasks. Regular maintenance and fluid checks can help prevent clutch failure, but if it does occur, it’s essential to have the transmission inspected and repaired by a professional.
One more common problem with the 68RFE transmission is solenoid failure. The solenoids are electrical components that control the flow of transmission fluid. If a solenoid fails, it can lead to erratic shifting, slipping gears, or transmission fluid leaks. Solenoid issues should be addressed promptly to prevent further damage to the transmission.
Upgrades and Modifications for 68RFE
When it comes to enhancing the performance of your 68RFE transmission, there are a variety of upgrades and modifications you can consider. One popular upgrade is installing a deeper transmission pan which helps to increase fluid capacity and improve cooling. This can be especially beneficial for trucks that tow heavy loads or operate in hot climates.
Another common modification is the addition of a aftermarket torque converter. Upgrading to a higher stall speed torque converter can improve the off-the-line performance of your vehicle and provide better towing capabilities. Additionally, installing a performance transmission cooler can help prevent overheating and extend the life of your transmission.
For those looking to take their 68RFE to the next level, there are also options for performance tuning. Upgrading the transmission control module (TCM) with a custom tune can optimize shift points, line pressure, and other parameters to maximize power and efficiency. Some tuners also offer the ability to adjust for tire size, gear ratio, and other modifications.
Maintenance Tips for 68RFE Transmission
Regular maintenance is crucial for keeping your 68RFE transmission in top condition and prolonging its lifespan. One important maintenance tip is to regularly check the transmission fluid level and condition. Low or dirty transmission fluid can cause serious damage to the transmission, so be sure to follow the manufacturer’s recommendations for fluid changes.
Another maintenance tip for the 68RFE transmission is to inspect and replace the transmission filter. A clogged or old filter can restrict fluid flow and lead to transmission issues. It is recommended to replace the filter every 30,000 to 60,000 miles, depending on your driving habits.
Lastly, avoid towing heavy loads or engaging in aggressive driving habits that can put excess strain on the transmission. By driving responsibly and maintaining your 68RFE transmission properly, you can ensure smooth operation and avoid costly repairs in the future.
Performance Tuning for 68RFE Transmission
When it comes to enhancing the performance of your Dodge 68RFE transmission, there are several upgrades and modifications that you can consider. One popular performance tuning option is to install a higher stall torque converter. This can help improve the overall drivability of your vehicle, especially if you have made other upgrades like adding more horsepower.
Another performance tuning option for the 68RFE transmission is to upgrade the valve body. This can help improve shift points and overall transmission performance. Upgrading the valve body can also help reduce the risk of clutch slippage, which can occur under high torque conditions.
Performance tuning for the 68RFE transmission can also involve reprogramming the transmission control module. This can help optimize the shift points and improve overall performance. By fine-tuning the transmission control module, you can make the most of any other modifications you have made to your transmission.
