Upgrading the 68RFE Transmission A Complete Guide

The 68RFE transmission is a popular choice among diesel truck enthusiasts, particularly those who own Dodge Ram trucks equipped with Cummins engines. While the 68RFE is known for its reliability and performance, many owners seek upgrades to enhance its capabilities, improve towing capacity, and extend its lifespan. In this article, we will explore various upgrades you can consider for the 68RFE transmission, and how they can improve your driving experience.

Understanding the 68RFE Transmission

The 68RFE is a six-speed automatic transmission that was introduced in the Dodge Ram trucks to handle increased torque and power from the Cummins 6.7L diesel engine. It features a unique design that combines hydraulic and electronic controls to provide smooth gear shifts. While the transmission is robust, there are inherent limitations when it comes to performance under heavy loads or high horsepower scenarios. This is where upgrades become significant.

1. Tuning the ECU One of the first upgrades many choose is to reprogram the Engine Control Unit (ECU). Advanced tuning can optimize the transmission's shifting patterns and increase power output, making it more responsive under load. By adjusting parameters such as shift points and pressure, drivers can experience significant improvements in throttle response and overall performance.

2. Upgraded Torque Converter The factory torque converter is designed for general use, but it's a potential weak point in high-performance applications. Upgrading to a high-performance torque converter can improve how power is transferred from the engine to the transmission. It allows for higher stall speeds, which can enhance acceleration and towing capabilities.

3. Better Cooling Solutions Heat is the enemy of any transmission, and the 68RFE is no exception. Adding an external transmission cooler can significantly reduce operating temperatures, especially during heavy towing or off-road use. Lower temperatures help maintain the integrity of the transmission fluid and can extend the life of the components.

4. Stronger Clutches and Bands Over time, the clutches and bands within the 68RFE can wear out, especially under heavy use. Upgrading to reinforced clutches and bands can provide better holding power and improve the overall performance of the transmission. This upgrade is often essential for those pushing their trucks to higher horsepower levels.

5. Valve Body Modifications The valve body controls fluid flow within the transmission and plays a critical role in shifting. Upgrading or modifying the valve body can lead to crisper, quicker shifts, reducing the chance of slippage. Some performance valve bodies are designed specifically for racing applications, providing even more aggressive shifting characteristics.

Installation Considerations

When considering upgrades to your 68RFE transmission, it’s crucial to factor in the installation. While some upgrades can be performed as DIY projects, others may require specialized tools and expertise. It’s often advisable to consult with professionals who specialize in transmission work to ensure proper installation and tuning.

Conclusion

Upgrading the 68RFE transmission can significantly enhance your driving experience, especially for those who engage in towing, off-roading, or performance driving. With a range of available options from ECU tuning to stronger components, owners can tailor their upgrade path to fit their specific needs and driving habits. By investing in these upgrades, you not only improve performance but also extend the transmission's lifespan, ensuring it can handle whatever challenges lie ahead on the road. Whether you're looking to boost horsepower, enhance towing capacity, or simply enjoy smoother, more engaging drives, upgrading your 68RFE transmission is a rewarding endeavor.
