Upgrading the 68RFE Transmission Enhancing Performance and Reliability

The 68RFE transmission, commonly found in Dodge Ram trucks, has gained a reputation for both its versatility and its challenges. While it’s designed to handle a broad range of applications, from daily driving to towing heavy loads, many enthusiasts and truck owners seek ways to upgrade this transmission to enhance its performance and reliability. In this article, we will explore various upgrades available for the 68RFE transmission and how they can significantly improve both performance and durability.

Understanding the 68RFE Transmission

The 68RFE is a six-speed automatic transmission that was introduced as part of the Chrysler 6-speed family in 2006. It is designed for use in Ram trucks with a Cummins diesel engine, offering improved fuel efficiency and better torque management compared to its predecessor, the 48RE. However, while the 68RFE is versatile, it can have shortcomings, especially when it comes to handling increased power and heavy towing applications.

As with any transmission, the 68RFE is not without its problems. Common issues include overheating under heavy loads, slipping in higher gears, and failure due to excessive torque. These issues become more pronounced when the vehicle is modified for higher horsepower, making upgrades essential for those who use their trucks for towing, off-roading, or performance driving.

Upgrades to Consider

1. Improved Cooling Solutions One of the top upgrades for the 68RFE is to enhance its cooling system. Upgraded transmission coolers or auxiliary cooling systems can help keep transmission temperatures down, especially during strenuous driving conditions. This is vital to extend the life of the transmission and prevent overheating—a common issue when towing or hauling heavy loads.

2. Aftermarket Transmission Valve Bodies Upgrading to an aftermarket valve body can significantly improve the performance of your 68RFE. A high-performance valve body provides quicker shifts and can handle more power, reducing the chances of slipping and increasing overall responsiveness. This upgrade is particularly beneficial for vehicles that have been modified for additional horsepower.

3. Heavy-Duty Torque Converters If you’re pushing the limits of your 68RFE’s power capabilities, investing in a heavy-duty torque converter is essential. An upgraded torque converter will improve torque multiplication and reduce slip, enhancing acceleration and overall performance. It can also reduce the chances of damage to other internal components by providing a more stable power transfer.

4. Stronger Clutches and Bands Upgrading the clutches and bands within the transmission is another effective way to improve durability. High-performance clutches can handle increased torque better than stock units, reducing the risk of slipping and extending the life of the transmission. Consider a full clutch kit designed for higher performance applications.

5. Transmission Control Modules (TCM) Upgrading the TCM can provide improved shift firmness and response, tailoring the transmission performance to better match your driving style. Some aftermarket TCM options allow for tuning capabilities, enabling you to fine-tune shift points and firmness to suit your needs.

6. Performance Programming Last but not least, utilizing a performance chip or programmer can drastically improve the overall transmission performance. By adjusting shift points, firmness, and torque management, you can ensure that your 68RFE is optimized for the power output of your engine.

Conclusion

Upgrading the 68RFE transmission is an effective way to enhance the performance and reliability of your Dodge Ram truck. Whether you are towing heavy loads, cruising off-road, or simply seeking a more responsive driving experience, the right modifications can make a significant difference. By investing in improved cooling solutions, high-performance valve bodies, heavy-duty torque converters, and other upgrades, truck owners can ensure their vehicles are equipped to handle demanding tasks while enjoying a stronger, more reliable performance. With proper care and the right enhancements, the 68RFE can continue to serve its purpose effectively for years to come.
