Twisted Punisher™ Ford C4 2WD Transmission

Rated 550–650 HP Depending on Application

High-Performance Street • Street/Strip • Modified & Stroker Small-Block Ford Builds

The Twisted Punisher™ C4 takes our Pro build to the next level for higher-horsepower street and street/strip applications.

We start with the increased clutch capacity and performance setup used in the Pro, then step up the hard parts where the C4 needs it. The Punisher gets a 300M billet input shaft, billet C-ratio servo, wide performance intermediate band and a more aggressive TransGo calibration.

Standard configuration is still a forward-pattern automatic. Put it in Drive and let it shift, or manually select the gears when you want more control.

🔥 PUNISHER CALIBRATION

The standard Punisher keeps the C4 automatic and forward pattern.

Put it in Drive and let it shift automatically. Pull it down into gear when you want to control the shifts yourself.

Compared with the Pro, the Punisher gets more line pressure, quicker shift timing, a wide performance intermediate band and billet C-ratio servo. The valve body, servo and band are set up to work together, not just thrown into the transmission as separate upgrades.

Reverse-pattern full-manual and transbrake valve bodies are available as options for builds that need them.

💪 300M BILLET INPUT SHAFT

The Punisher comes standard with a:

0.839" 26/24-Spline 300M Billet Steel Input Shaft

This is standard in the Punisher, not an add-on.

The late C4 26/24 configuration gives us the 26-spline converter-side setup and the stronger shaft we want for this build.

⚙️ BILLET C-RATIO SERVO

The Punisher steps up to a Billet C-Ratio Intermediate Servo.

The larger apply area gives us more holding force on the intermediate band and works with the wide performance band and increased line pressure for a quicker, more positive 1–2 shift.

This is the complete billet C-ratio servo piston setup, not just a billet servo cover.

⚠️ TORQUE CONVERTER NOT INCLUDED

Please select a torque converter from the available options if one is needed.

The Punisher is built around the late-model 26-spline converter-side input configuration.

If you purchase a converter with your transmission, we will supply the correct converter to match the C4 being built.

For higher-horsepower, stroker, boosted or street/strip combinations, stall speed needs to be matched to the engine, cam, vehicle weight, rear gear, tire size and intended use.

Flexplate is NOT included.

⚠️ PLEASE CONFIRM 157T OR 164T

You MUST verify whether your current application uses a:

• 157-Tooth Application
• 164-Tooth Application

Do not go by vehicle year alone.

If the engine, transmission, bellhousing or drivetrain has been changed, tell us what is currently installed in the vehicle.

🚗 APPLICATION

Rated 550–650 HP Depending on Application

Built for properly matched:

• Modified 289 / 302 Ford Small Blocks
• Performance 351W Applications
• Stroker Small-Block Ford Builds
• Naturally Aspirated Performance Builds
• Mild Boost / Power-Adder Applications
• Classic Ford Street Cars
• Mustangs, Falcons, Fairlanes, Mavericks & Cougars
• Street Rods & Restomods
• High-Performance Street
• Street / Strip

550–650 HP is application dependent.

A light street car on a radial is not the same load as a heavy car on a sticky tire leaving hard at the track. Vehicle weight, engine torque, tire, rear gear, converter, power adder and how the car is being used all matter.

If you're at the upper end of the rating, give us the complete combination so we can build it accordingly.

🔥 AVAILABLE PERFORMANCE UPGRADES

The standard Punisher does not need every race part we offer. These are available when the combination calls for them:

• Billet Front Oil Pump – $699
• 8-Pinion 2.20 Ratio First Gear Planetary – $671.95
• 26-Spline Billet Aluminum Bolt-Together Torque Converter – $1,095
• C4 Reverse Pattern Full Manual Valve Body – $399
• Full CNC Billet Aluminum TransBrake Valve Body – $599
• Billet CNC 1350 U-Joint Slip Yoke – $109.95

The 8-pinion planetary uses a 2.20 first-gear ratio, and we also have the billet pump and CNC billet transbrake valve body available for builds moving beyond the standard Punisher setup.
