Complete Transmissions

2007.5–2009 Dodge Ram 2500 & 3500 6.7L Cummins Complete Transmissions

Eliminate catastrophic clutch slip, put an end to broken shafts and burnt-up clutches under heavy commercial loads, and completely bulletproof your drivetrain with premium 2007.5–2009 6.7L Cummins 3rd Gen complete transmissions from Full Force Diesel. Heavy-duty Ram 2500 and 3500 trucks working under severe commercial workloads, hauling heavy gooseneck trailers across mountain grades, or running high-output performance engine tuning quickly overwhelm factory automatic 68RFE or manual transmissions. Over thousands of miles of heavy-duty operation, stock internal components fatigue, line pressures drop, and factory friction plates fail under sustained high torque. Upgrading to a heavy-duty built complete transmission assembly ensures your truck can handle maximum towing power reliably.

Advanced Drivetrain Engineering: Built Automatic and Manual Assemblies

Transitioning away from a failing factory transmission to a heavy-duty, machine-shop-built complete assembly completely transforms your truck's power handling capability:

• Heavy-Duty Built Automatic Transmissions: Engineered with reinforced cases, high-capacity multi-disc torque converters, billet shafts, upgraded valve bodies, and heavy-duty friction clutches designed to handle extreme towing torque without slipping or overheating.

• Robust Manual Transmission Assemblies: Fully synchronized heavy-duty manual replacement transmissions built with upgraded internal gears, heavy-duty main shafts, and high-capacity clutch compatibility for total driver control under heavy loads.

Reinforced Internal Hard Parts and Torque Management

Our selection of complete transmission assemblies features rugged hardware engineered for a direct-fit, long-lasting installation:

• Billet Maraging Steel Shafts and Upgraded Drums: Built with high-strength rotating components that eliminate twisting, snapping, and spline stripping under high-boost, heavy-throttle towing conditions.

• Optimized Hydraulic Control and Cooling: Integrated valve bodies and deep-capacity cooling pans maintain high line pressure and lower operating temperatures to prevent thermal breakdown on long hauls.

At Full Force Diesel, we carry the rugged, street-tested mechanical hardware and machine-shop-certified components your transitional 3rd Generation inline-six needs to put maximum power down reliably.
