Transmission Rebuild Kits

2010–2018 Dodge Ram 2500 & 3500 6.7L Cummins 68RFE Heavy-Duty Transmission Rebuild Kits

Eliminate slipping gears, prevent catastrophic clutch failure under heavy fifth-wheel loads, and upgrade your common-rail automatic transmission to handle serious horsepower with premium 2010–2018 6.7L Cummins 4th Gen transmission rebuild kits from Full Force Diesel. Heavy-duty Ram 2500 and 3500 trucks equipped with the factory 68RFE six-speed automatic transmission are notorious for burning up internal clutches, flexing weak OD drums, and struggling under the immense torque output of tuned 6.7L diesel engines. When factory friction plates glaze over and line pressures drop, limp mode and slipping shifts are inevitable. Upgrading to an engineered, heavy-duty master rebuild kit or performance stage package transforms your transmission's holding capacity and long-term durability.

Advanced Internal Reinforcement: High-Energy Clutches and Billet Drums

Transitioning away from fragile factory components to heavy-duty upgraded internals completely secures your drivetrain's power transfer:

• High-Energy Friction Plates and Steels: Performance rebuild kits feature increased-capacity clutch packs manufactured from heavy-duty Raybestos, Alto, or BorgWarner friction materials. By adding extra clutches and thicker steel plates to the Underdrive, Overdrive, and 2C circuits, these kits drastically increase surface apply area and thermal mass to prevent slipping under heavy throttle.

• Reinforced Billet Overdrive Drums and Pressure Plates: Factory stamped-steel clutch drums are prone to flexing and distorting under high line pressures, leading to uneven clutch wear. Upgrading to heavy-duty billet aluminum drums and thick reaction plates eliminates structural deflection, ensuring flat, uniform clamping force across every shift.

Complete Hydraulic Control: Valve Body Upgrades and Zero-Cavitation Filters

Our selection of common-rail transmission components features comprehensive hardware solutions engineered to optimize fluid dynamics and line pressure:

• Billet Accumulator Pistons and Solenoid Plates: Factory plastic accumulator pistons are prone to cracking and scoring their bores, resulting in internal pressure leaks. Rebuilding with precision-machined billet aluminum pistons and upgraded separator plates stops cross-leaks and optimizes shift firmness.

• High-Flow Filtration and Deep Pans: To combat fluid aeration and heat soak during grueling towing sessions, these kits pair seamlessly with deep aluminum transmission pans and zero-cavitation filter kits, maintaining maximum fluid volume and lower operating temperatures.

At Full Force Diesel, we carry the rugged, street-tested mechanical hardware and machine-shop-certified components your 4th Generation inline-six needs to remain completely dependable.
