☠️ Twisted Punisher™ Big Block E4OD Performance Transmission

650 HP Rated | Ford Big-Block / 385-Series Pattern

Ford E4OD • 1989–1998

351M • 400 • 370 • 429 • 460 • 385-Series Based Builds

High Performance • Modified Big Blocks • Street Trucks • Heavy-Duty Use

The Twisted Punisher™ Big Block E4OD is our 650 HP build for modified Ford big-block applications.

This is where we step past the Pro and start replacing the hard parts that become weak points as horsepower and torque go up.

The Punisher gets a Raybestos GPZ clutch package, increased clutch capacity, 6-pinion steel forward planetary, steel overdrive planetary, hardened heavy-duty input shaft, 45-element intermediate sprag, TransGo E4OD-HD2 performance valve-body setup, and a billet single-disc lockup converter.

Rated up to 650 HP.

🔥 RAYBESTOS GPZ CLUTCH PACKAGE

The Punisher uses Raybestos GPZ performance frictions in the main clutch packs.

GPZ is built for high-stress truck and performance applications where the transmission still needs to handle vehicle weight, heat and load.

✔️ GPZ Forward Frictions

✔️ GPZ Direct Frictions

✔️ GPZ Intermediate Frictions

✔️ GPZ Overdrive Frictions

✔️ High-Static Low / Reverse Frictions

✔️ Graphitic Coast Clutches Where Applicable

🔧 INCREASED CLUTCH CAPACITY

✔️ High-Capacity Forward Clutch

Forward clutch is set up for increased capacity and correct clutch clearance.

✔️ High-Capacity Direct Clutch

Direct clutch is set up for increased holding capacity.

✔️ Increased Intermediate Clutch Capacity

✔️ Increased Overdrive Clutch Capacity

Pressure plates are machined or selected where required to fit the increased clutch stack while maintaining proper clearance.

✔️ Heavy-Duty Intermediate Band

🔩 PUNISHER™ HARD PARTS

This is where the Punisher makes the jump from the Pro.

Steel overdrive planetary installed in the OD section.

✔️ Hardened Heavy-Duty Input Shaft

The Punisher gets an upgraded hardened input shaft for the increased power and shock load of modified big-block applications.

⚙️ TRANSGO E4OD-HD2 PERFORMANCE VALVE BODY

✔️ TransGo E4OD-HD2 Reprogramming Kit

The Punisher moves away from the Pro's tow/haul Tugger calibration and uses the TransGo E4OD-HD2 performance setup.

Includes:

✔️ Pressure regulator boost valve

✔️ 1-2 shift valve spring

✔️ 2-3 shift valve

✔️ Shift-firmness calibration plate

✔️ Line-to-lube update

✔️ OD housing spiral-lock snap ring

✔️ Converter feed updates

The valve body is completely cleaned, checked and set up for shorter, positive shifts under power while retaining automatic operation in Drive.

✔️ Gear Command™ on Applicable Early E4ODs

On applicable 1989–1995 E4OD applications, first and second gear can be held when manually selected while retaining automatic operation in Drive.

Gear Command is not available on 1996-up applications.

⚡ E4OD SOLENOID PACK

✔️ Solenoid Pack Inspected & Tested

The correct solenoid pack is matched to the transmission year and configuration.

Solenoid operation is checked during the build. Failed or out-of-spec units are replaced.

🔩 CENTER SUPPORT & CLUTCH FEED UPDATES

The center support and case are checked closely during teardown.

✔️ Center Support Checked for Case-Lug Wear

✔️ Center Support Sealing Updates

✔️ Intermediate Clutch Feed Sealing Updates

✔️ Direct Clutch Feed Sealing Updates

✔️ One-Piece Rear Case Bushing Where Applicable

Anything worn, cracked, damaged or out of specification is replaced.

🚙 BILLET PERFORMANCE TORQUE CONVERTER INCLUDED

✔️ Billet Single-Disc Lockup Converter

Every Twisted Punisher™ Big Block E4OD includes a billet single-disc lockup torque converter.

The converter is matched to the actual combination based on:

• Engine
• Horsepower
• Camshaft
• Vehicle weight
• Rear gear
• Tire size
• Intended use

A factory 460 and a modified 429, stroker 460 or other 385-series performance build do not automatically use the same converter.

🔥 Billet Triple-Disc Lockup Converter Available

For higher torque, boosted combinations, aggressive use or customers wanting additional lockup capacity, a billet triple-disc converter is available as an upgrade.

❄️ HIGHLY RECOMMENDED DEEP ALUMINUM PAN UPGRADE

For a 650 HP big-block E4OD, we HIGHLY RECOMMEND adding our:

🔥 High-Capacity Deep Aluminum Cooling Pan

✔️ Adds approximately 5–7.5 quarts of fluid capacity

✔️ Finned cast-aluminum construction

✔️ Magnetic drain plug

✔️ Temperature-sender port where applicable

✔️ Additional fluid capacity for better heat control

Exact pan and added capacity vary by application.

OPTIONAL UPGRADE. NOT INCLUDED.

🧊 COOLER REQUIREMENT

A properly sized auxiliary transmission cooler is REQUIRED.

The cooler and cooler lines must be flushed and checked for unrestricted flow before installation.

If the previous transmission put metal or clutch material into the cooling system, replace the contaminated cooler.

The optional deep aluminum pan adds fluid capacity, but it does not replace the need for a properly sized external cooler.

🛠️ BIG-BLOCK / 385-SERIES APPLICATIONS

The Punisher uses the Ford big-block / 385-series E4OD bellhousing pattern.

Primarily Ford applications originally equipped with the:

7.5L / 460 EFI

Including applicable:

• F-250
• F-350
