🔥⚙️ TWISTED STREET™ 4L80E PERFORMANCE TRANSMISSION

UP TO 500 HP STREET, TOWING & WORK-TRUCK BUILD

The Twisted Street™ 4L80E is built for daily drivers, tow vehicles, work trucks, mild performance engines, and LS swaps that need more than a stock replacement.

This is an upgraded street build with better clutches, added direct-clutch capacity, corrected hydraulics, new internal electronics, and an OEM-style lockup converter.

🔥 POWER & USE

✔ Rated for up to 500 Horsepower

✔ Daily driving and work-truck use

✔ Mild towing and hauling

✔ Stock and mildly upgraded engines

✔ Mild LS swap applications

✔ Firm, street-friendly shifts

✔ Available in 2WD and 4WD

Final rating depends on vehicle weight, engine torque, tuning, gearing, tire size, converter, and use.

⚙️ COMPLETE STREET BUILD

🔧 COMPLETE MASTER OVERHAUL KIT

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

This restores proper sealing, oil control, and internal clearances

.

🔥 HIGH-ENERGY CLUTCHES & NEW STEELS

Upgraded friction material handles more heat and load than standard replacement clutches while maintaining smooth street engagement.

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

🔥 INCREASED DIRECT-CLUTCH CAPACITY

The direct clutch is set up for added holding power where clearance allows.

This helps prevent clutch slip during Third-gear operation, towing, and heavy throttle.

🔥 HEAVY-DUTY INTERMEDIATE BAND

A new wide heavy-duty band improves holding power and durability during loaded operation.

🔥 UPDATED 34-ELEMENT INTERMEDIATE SPRAG

The updated sprag is stronger than early factory designs and helps prevent sprag and intermediate clutch failure.

⚙️ TRANSGO SHIFT-CORRECTION SYSTEM

Corrects common pressure and shift-timing problems while maintaining firm, controlled street shifts.

🔧 STREET 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 as needed to improve line pressure, clutch apply, shift timing, and converter lockup.

🔥 SONNAX UPDATES AS NEEDED

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, delayed engagement, clutch slip, and converter problems.

🔧 UPDATED PUMP

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

Hardened pump rings and recommended pump updates improve pressure control and reliability.

🔧 CENTER-SUPPORT UPDATE

The center support and retaining hardware are inspected and updated as needed to prevent movement inside the case.

🔧 NEW INTERNAL ELECTRONICS

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

Electronics are matched to the transmission year and vehicle application.

⚙️ OEM-STYLE LOCKUP CONVERTER INCLUDED

✔ OEM-style gas lockup converter

✔ Approximately 2,000–2,200 RPM stall

✔ Smooth street engagement

✔ Matched to the engine and vehicle

✔ Built for daily driving, towing, and mild performance

Actual stall speed depends on engine torque, camshaft, vehicle weight, gearing, and tire size.

Billet-cover and higher-stall converter upgrades are available for modified engines, turbo or supercharged combinations, and more aggressive LS swaps.

🔥 WHY UPGRADE FROM STOCK?

✔ Better clutch holding power

✔ Increased direct-clutch capacity

✔ Stronger intermediate sprag and band

✔ Improved line-pressure control

✔ More dependable converter lockup

✔ New internal electronics

✔ Common valve-body wear repaired

✔ Firm shifts without race-transmission harshness

🌡️ COOLING RECOMMENDATIONS

An external transmission cooler is strongly recommended for towing, hauling, and heavy vehicle use.

Cooler lines and heat exchangers must be properly flushed or replaced before installation. Contamination from the previous transmission can damage the new build.

🚗 COMMON APPLICATIONS

✔ GMC Sierra 2500 and 3500

✔ Chevrolet Suburban 2500
