🔥 Twisted Street™ 6L80E Performance Transmission

High-Energy Clutches & Steels • Super Duty Billet Cover Torque Converter INCLUDED

Stronger Than Stock. Daily Driver Ready. Built the Twisted Torque™ Way.

The Twisted Street™ 6L80E is our entry-level performance build for GM cars, trucks and SUVs that need more than a factory-style replacement without stepping into an aggressive race transmission.

Every transmission is completely torn down, cleaned, inspected and built in-house. We address the known 6L80E clutch, converter, pump and hydraulic wear areas, build the clutch assemblies with high-energy clutches and steels, and pair the transmission with a Super Duty billet cover torque converter at stock stall speed.

💥 Every Twisted Street™ 6L80E includes our Super Duty billet cover torque converter at stock stall.

Not optional. Not an add-on. It is part of the Street build.

⚙️ FITMENT & BUILD MATCHING

We do NOT sell one universal 6L80E for every application.

Every transmission is:

✔ Built to order

✔ Matched to your vehicle application

✔ Matched to your drivetrain

✔ Built around how the vehicle is actually used

The correct 6L80E configuration is determined by your VIN, year, make, model, engine and 2WD/4WD configuration.

VIN verification is required for proper fitment.

🔧 TWISTED STREET™ 6L80E BUILD

✔ High-Energy Clutches & Steels

The clutch assemblies are rebuilt using high-energy friction material and matching steels for increased heat resistance and holding capacity while maintaining street-friendly operation.

✔ 1-2-3-4 Clutch Assembly

Completely disassembled and inspected. The clutch pack is rebuilt and clutch clearance is checked during assembly.

✔ 3-5-Reverse Clutch & Drum

The 3-5-Reverse drum is inspected for known cracking and weld failure. The clutch pack is rebuilt and clearance is verified.

Drums that meet our build specifications are reused. Drums that do not meet specification are replaced.

✔ 4-5-6 Clutch Assembly

The 4-5-6 clutch pack is rebuilt with high-energy clutches and steels, and apply clearance is checked during assembly.

✔ Reconditioned & Recalibrated Valve Body

The valve body is inspected and corrected for hydraulic wear that can affect pressure control, clutch apply, shift operation and converter clutch operation.

✔ TransGo TCC Hydraulic Correction

The TCC regulator and clutch-select circuits are known areas of concern in the 6L80E. Our hydraulic correction addresses converter clutch regulation and clutch-select valve operation. TransGo specifically identifies these circuits as sources of TCC cycling/surge and clutch-select valve sticking.

✔ Pressure Regulator & Boost Valve Correction

The pressure regulator and boost circuits are inspected and corrected as required. Wear in these areas can cause improper line-pressure rise, soft or flaring shifts, burned frictions and TCC slip.

✔ Pump Inspection & Setup

The pump body, rotor, slide, vanes, pressure-regulator circuit and internal clearances are inspected for wear and proper operation.

We do not automatically replace a good OE pump simply so we can put “NEW PUMP” on a parts list.

If the pump does not meet our build specifications, it is replaced.

✔ Complete Bushing Kit

Bushings are replaced throughout the transmission to restore proper support and internal clearances.

✔ New Gaskets, Seals & Sealing Rings

The transmission receives a complete sealing service during assembly.

✔ New Transmission Filter

Installed with every build.

✔ OE Hard Parts Inspected & Measured

Drums, shafts, hubs, planetary assemblies, stator support and one-way clutch are cleaned and inspected for wear or damage.

Serviceable OE hard parts are retained when they meet our build specifications.

Anything that does not meet spec gets replaced.

💥 SUPER DUTY BILLET COVER TORQUE CONVERTER — INCLUDED

Every Twisted Street™ 6L80E includes a Super Duty billet cover torque converter.

The billet cover gives us a stronger converter foundation while retaining stock stall speed.

Why Stock Stall?

Because Twisted Street™ is built to be driven on the street.

Stock stall maintains:

✔ Predictable engagement

✔ Factory-style street manners

✔ Daily-driver drivability

✔ Proper operation with stock and mildly modified combinations

We're not throwing a high-stall converter into the package simply because the word “performance” is on the transmission.

The converter and transmission are built to work together.

⚙️ HIGH-ENERGY CLUTCHES STILL NEED PROPER PRESSURE

Putting better friction material into a 6L80E does not fix a worn hydraulic system.

Wear in the pressure regulator, boost, TCC and related hydraulic circuits can affect line pressure, clutch apply and converter clutch operation. TransGo's current 6L80 repair lineup specifically addresses the pressure regulator, boost valve, TCC regulator and clutch-select circuits for these reasons.

That's why Twisted Street™ addresses the pump and valve body along with the clutch assemblies.

Proper hydraulic operation and clutch clearance are part of the build — not something we try to hide with a longer parts list.

⚙️ WHAT TWISTED STREET™ IS BUILT FOR

Perfect for:

🔥 Daily-driven GM cars, trucks and SUVs

🔥 Stock and mildly modified engines

🔥 Common bolt-on modifications

🔥 Street-driven LS applications

🔥 5.3L, 6.0L and 6.2L GM combinations

🔥 Light towing and hauling within the vehicle's intended operating range

🔥 Customers who want more than a stock replacement while maintaining factory-style drivability

Vehicle weight, engine torque, tire size, tuning, towing requirements and intended use all matter when selecting the correct transmission.

⚡ TECHM ELECTRONICS PACKAGE — SELECTION REQUIRED

Every Twisted Street™ 6L80E order requires a TECHM electronics selection.

FULLY PROGRAMMED TECHM BY VIN — +$399

Provide your VIN at checkout and we will supply the TECHM programmed to your vehicle before shipment.

This eliminates the need for full dealer VIN programming after installation.

Required setup, reset or relearn procedures must still be completed when applicable.

VIN MUST BE PROVIDED AT CHECKOUT WHEN SELECTING THE FULLY PROGRAMMED TECHM OPTION.

BLANK TECHM — INCLUDED IN PRICE

Decline the pre-programmed option and the transmission will be supplied with a blank TECHM at no additional charge.

The blank TECHM must be programmed to the vehicle VIN after installation by a GM dealer or qualified repair facility using proper GM-compatible programming equipment.
