Dodge 68RFE Transmission

Everything You Need to Know About the Dodge 68RFE Transmission

The 68RFE is a six-speed automatic transmission developed by Chrysler for heavy-duty Ram trucks equipped with the 6.7L Cummins Turbo Diesel engine. Introduced for the 2007 model year, it was designed to handle the increased torque demands of diesel-powered pickups used for towing, hauling, and commercial applications.

While the 68RFE is capable of handling demanding workloads, its longevity depends on proper maintenance, driving habits, towing conditions, and build quality. For trucks that regularly tow heavy loads or produce increased horsepower, upgraded internal components can improve durability and reliability.

At Gears Transmission, we diagnose, rebuild, and upgrade 68RFE transmissions using premium components and proven rebuilding practices. Whether your truck is stock or heavily modified, we can build a transmission to match your needs.
