Twisted Executioner™ 68RFE Transmission 850+ HP
Fits 2007.5–2018 Ram 2500 / Ram 3500
Rated 850+ HP / 1,500+ lb-ft
Maximum Effort. Full Billet. Built for Extreme Diesel Power.
At this level, the factory 68RFE platform is completely inadequate
Common failures at 800+ HP include:
• Input shaft torsional failure
• Intermediate and output shaft twist
• Overdrive clutch housing distortion
• 2C clutch collapse under load
• Hydraulic pressure loss and clutch slip
• Pump cavitation and fluid instability
• Converter clutch failure
• Internal component deflection
👉 The Twisted Executioner™ is engineered to eliminate these limitations

This transmission is designed for high-performance applications and requires proper tuning
• ECM tuning directly affects line pressure, shift timing, and converter operation
• Improper tuning can result in clutch failure, overheating, or transmission damage
👉 A built transmission will not correct a poor tune
Professional diesel tuning is required for optimal performance and reliability
We don’t rebuild transmissions — we engineer solutions
Every unit is:
• Fully disassembled, inspected, and measured
• Built with billet and reinforced components where failure occurs
• Calibrated for extreme torque and load conditions
• Designed to survive where stock and basic builds fail
👉 Built for customers who demand maximum strength and reliability
⚠ Core return required
Core must be complete and rebuildable
Core charge applies if no core is returned
