Twisted Executioner™ E4OD Diesel Transmission 750HP
Fits 1990–1997 Ford F-250 / F-350 – 7.3L IDI & 7.3L Power Stroke
The Twisted Executioner™ E4OD is engineered for diesel trucks pushing serious power and torque — the kind of setups that destroy standard builds.
Rated for up to 750 HP and 1,200+ lb-ft of torque, this transmission is designed to survive heavy towing, aggressive tuning, and real-world abuse without repeated failure.
This is not a rebuild.
This is a fully engineered survival package.
Ideal for:
• High horsepower 7.3 Powerstroke builds
• Heavy towing under power
• Performance diesel trucks
• Fleet and work trucks under constant load
• Customers tired of replacing transmissions
If you’ve already been through one or two transmissions…
this is where that cycle ends.
• BILLET INPUT SHAFT (300M EXTREME DUTY)
Eliminates one of the most common catastrophic failure points under diesel torque
• BILLET INTERMEDIATE SHAFT
Prevents twisting and breakage under shock load and aggressive shifting
• UPGRADED HARDENED PLANETARY GEARSET
Improved strength and durability under sustained load and high horsepower
• REINFORCED DRUMS & APPLY COMPONENTS
Critical areas strengthened to handle increased pressure and torque
• MAX CAPACITY CLUTCH PACKS (ALL CLUTCH MODULES)
Increased clutch count for significantly higher holding power
• TWISTED TORQUE™ HD CLUTCHES AND STEELS
Engineered for heat resistance and long-term durability
• HEAT-TREATED / KOLENE® STEELS
Improved wear resistance and reduced heat breakdown
• WIDE HIGH PERFORMANCE BAND (KEVLAR OR EQUIVALENT)
Stronger apply and improved longevity under load
⚙️ HYDRAULICS & CONTROL
• VALVE BODY – MODIFIED & UPDATED THE TWISTED TORQUE™ WAY
Custom calibration for line pressure, shift timing, and clutch protection
• PUMP – MODIFIED & UPDATED THE TWISTED TORQUE™ WAY
Improved oil flow and pressure stability under heavy load
• INCREASED LINE PRESSURE STRATEGY
Prevents clutch slip and heat-related failures
• FULL HYDRAULIC SYSTEM OPTIMIZATION
Built to support high horsepower diesel applications
• NEW SHIFT SOLENOIDS
• NEW EPC SOLENOID
• NEW TCC SOLENOID
• NEW INTERNAL WIRING HARNESS
• NEW SENSORS WHERE REQUIRED
No reused electronics — no weak links.
• IMPROVED LUBE CIRCUITS
• ENHANCED COOLING FLOW THROUGHOUT TRANSMISSION
Because heat is what kills E4OD units — this build is designed to control it.
• BILLET MULTI-DISC LOCK-UP TORQUE CONVERTER
• Designed for diesel torque, towing, and high horsepower use
• Stall speed matched to your setup (tow, street, performance)
Because this build eliminates the weak points that destroy standard E4OD units:
✔ Billet shafts to prevent catastrophic failure
✔ Maximum clutch capacity for holding power
✔ Hydraulic calibration designed for diesel torque
✔ Brand new electronics throughout
✔ Cooling and lubrication improvements for longevity
Most failures come from:
• Input shaft breakage
• Clutch burnout
• Heat saturation
• Hydraulic inefficiency
This build addresses every one of those — directly.
If your truck is stock or lightly modified — this is overkill.
If you are pushing power, towing hard, or have already broken a transmission…
this is exactly what you need.
Performance application warranty applies.
(See full warranty details for high horsepower builds)
Each transmission is built specifically for your:
• Vehicle
• Engine setup
• Power level
• Intended use
You can keep replacing transmissions…
or you can fix the problem once.
This is the one you buy when you’re done playing around.
