🔥💀 TWISTED PUNISHER DIESEL™ 4L80E TRANSMISSION

600–750 HP EXTREME-DUTY TOWING & PERFORMANCE BUILD

The Twisted Punisher Diesel™ 4L80E is built for high-output diesel trucks, severe towing, heavy RVs, large tires, and drivers pushing beyond the limits of our Pro build.

The Punisher adds billet input and forward-drive parts, five-pinion planetary gears, maximum-capacity clutch packs, stronger center-support retention, a deep aluminum pan, and a low-stall billet triple-disc converter.

🔥 POWER & USE

✔ 600–750 Horsepower

✔ High-output diesel engines

✔ Severe-duty towing and hauling

✔ Heavy work trucks and RVs

✔ Larger tires and heavier vehicles

✔ Firm, controlled performance shifts

Final rating depends on engine torque, vehicle weight, tuning, gearing, towing load, converter lockup, and operating temperature.

⚙️ COMPLETE PUNISHER DIESEL BUILD

🔧 COMPLETE MASTER OVERHAUL KIT

New gaskets, seals, sealing rings, bonded pistons, bushings, bearings, thrust washers, and wear items.

This restores proper sealing, oil control, and internal clearances.

🔥 HIGH ENERGY HD TWISTED™ CLUTCHES & STEELS

Our High Energy HD Twisted™ clutch and steel package is set up for maximum holding power and better heat control under high diesel torque.

New steels give the clutches a clean, flat surface to apply against.

🔥 MAXIMUM-CAPACITY DIRECT CLUTCH

The direct clutch is dual-fed and set up with increased clutch capacity where clearance allows.

This gives the transmission more holding power in Third gear and helps prevent direct-clutch slip under heavy throttle and towing load.

🔥 INCREASED FORWARD-CLUTCH CAPACITY

The forward clutch is set up for added holding power during loaded acceleration and high-torque street use.

💀 300M BILLET INPUT SHAFT

The billet input shaft replaces the factory shaft at one of the main load points in the transmission.

It provides added strength against high diesel torque, aggressive converter lockup, and heavy-throttle operation.

💀 BILLET FORWARD CLUTCH HUB

The billet forward hub provides stronger support for the forward-clutch assembly.

This upgrade becomes important once converter lockup, clutch pressure, and engine torque are increased.

🔥 FIVE-PINION FRONT & REAR PLANETARY GEARS

The stronger five-pinion geartrain spreads the load across more pinions than the factory four-pinion setup.

This improves strength for heavy trucks, RVs, larger tires, and repeated towing load.

🔥 HEAVY-DUTY INTERMEDIATE BAND

A new wide heavy-duty band provides stronger holding power and better durability under load.

🔥 UPDATED 34-ELEMENT INTERMEDIATE SPRAG

The updated sprag and inspected sprag race improve strength during high-load shifts.

Any worn or questionable race is replaced.

🔥 SPIRAL-LOCK CENTER-SUPPORT RETENTION

The upgraded center-support setup provides stronger retention and helps prevent support and snap-ring movement under increased pressure.

⚙️ TRANSGO HD2 SHIFT PACKAGE

The TransGo HD2 package increases clutch pressure and improves shift timing and converter control.

The setup is matched to the vehicle so shifts remain firm and controlled without unnecessary drivetrain shock.

🔧 PUNISHER VALVE BODY — TWISTED TORQUE™ SPEC

The valve body is taken apart, cleaned, inspected, and checked for worn valves and pressure loss.

Worn areas are repaired to improve line pressure, clutch apply, shift timing, and converter lockup.

🔥 SONNAX UPDATES

Sonnax valves and sleeves are used where wear is found in the pressure, boost, oil-feed, and converter circuits.

These repairs help prevent low pressure, clutch slip, delayed engagement, and converter lockup problems.

🔧 HIGH-PRESSURE PUMP BUILD

The pump is set up for increased pressure, proper converter feed, cooler flow, and lubrication.

Hardened pump rings and recommended pump updates improve pressure control and reliability under severe load.

🔧 NEW INTERNAL ELECTRONICS

New EPC solenoid, shift solenoids, TCC solenoid, internal wiring harness, and applicable sensors are installed.

This removes old electrical parts that commonly cause pressure, shifting, and converter lockup problems.

⚙️💀 LOW-STALL BILLET TRIPLE-DISC CONVERTER INCLUDED

✔ One-piece billet front cover

✔ Triple-disc lockup clutch

✔ Low-stall diesel setup

✔ Reinforced and furnace-brazed construction

✔ Heavy-duty bearings and upgraded turbine hub

✔ Increased lockup holding power

✔ Stall matched to the engine, turbo, gearing, and vehicle

The triple-disc lockup clutch provides more holding area and reduces converter slip under high diesel torque.

The converter and transmission are built as a matched package.

⚙️🔥 DEEP CAST-ALUMINUM PAN INCLUDED

✔ Additional fluid capacity

✔ Cooling fins

✔ Better heat control

✔ Added pan-rail support

✔ Serviceable drain plug

More fluid and better heat control help protect the transmission during towing and heavy use.

🔥 WHY STEP UP FROM PRO?

The Twisted Pro Diesel™ is built for upgraded engines, HD towing, work trucks, and RV use.

The Twisted Punisher Diesel™ adds the hard parts, clutch capacity, and converter holding power needed for serious diesel torque.

✔ 300M billet input shaft

✔ Billet forward clutch hub

✔ Five-pinion front and rear planetary gears

✔ Maximum-capacity direct clutch

✔ Increased forward-clutch capacity

✔ Spiral-lock center-support retention

✔ TransGo HD2 shift package

✔ High-pressure pump and valve body

✔ Low-stall billet triple-disc converter

✔ Deep cast-aluminum pan

🚨 TUNING & COOLING

Proper engine and transmission tuning are required at this power level.

A high-capacity external transmission cooler, unrestricted cooler lines, and clean heat exchangers are required for towing and severe-duty use.

The transmission cannot protect itself from incorrect tuning, uncontrolled torque, overheating, or converter lockup commanded at the wrong time.

🚗 COMMON APPLICATIONS

✔ Chevrolet and GMC diesel trucks

✔ High-output 6.2L and 6.5L diesel applications

✔ Hummer H1 diesel applications

✔ Heavy RV and motorhome applications

✔ Diesel conversions using a GM 4L80E

✔ Two-wheel-drive and four-wheel-drive builds

✔ Modified diesel trucks requiring a stronger overdrive transmission

Every transmission is built to order for the vehicle, engine, and intended use.
