Twisted Street™ 6R80 Performance Transmission | Up to 450 HP
F-150 • Mustang • Expedition • Navigator • Select Ford / Lincoln Applications • Coyote / Modular Swaps • Custom 6R80 Applications
Every Twisted Street™ 6R80 is built to the ordered year, engine, drivetrain configuration and intended use.
The Twisted Street™ 6R80 is our OEM+ performance build for stock and mildly modified vehicles needing a stronger, more thoroughly prepared transmission than a basic stock replacement.
✔ Daily Drivers
✔ Work Trucks
✔ Light Towing & Hauling
✔ Stock & Mild Performance Builds
✔ Naturally Aspirated Coyote Applications
✔ Mild EcoBoost Applications
✔ Coyote / Modular Swaps
✔ Larger Tire & Gear Combinations
EcoBoost applications are evaluated by torque as well as horsepower.
Tuned EcoBoost engines can produce substantial low-RPM torque even when peak horsepower remains within the Street power range. Higher-torque or aggressively tuned combinations may require a Twisted Pro™ or Twisted Punisher™ 6R80.
✔ Complete Master Rebuild Kit
✔ Twisted Torque™ HD / High-Energy Frictions
✔ Performance Steels
✔ Updated Bonded Pistons & Internal Seals
✔ Complete Bushing Replacement
✔ New Pump Bushing
✔ Bearings & Thrust Components Inspected / Replaced as Required
✔ Clutch Clearances Checked & Set During Assembly
✔ Internal Endplay Checked & Set
✔ NEW Lead Frame / Connector Plate on Every Street Build
✔ Solenoids Inspected & Tested
✔ Internal Electrical Connections Inspected
✔ New Application-Correct Filter
The lead frame is a common 6R80 failure area, so it is replaced as part of every Twisted Street™ build rather than reused.
✔ Pump Completely Disassembled & Inspected
✔ Pump Reconditioned & Updated
✔ Pressure Regulator Circuit Inspected & Updated
✔ TCC / Converter Regulator Circuit Updated
✔ Valve Body Completely Disassembled & Cleaned
✔ Valve Body Wear Inspected & Corrected as Required
✔ Solenoid / Lube Regulator Circuits Inspected
✔ Street-Oriented Shift Calibration
✔ Sonnax / TransGo Hydraulic Repairs Used Where Required
GEN 1 6R80
✔ TransGo T95165 Hydraulic / Shift Kit
GEN 2 6R80
✔ TransGo T95165A Hydraulic / Shift Kit
Pressure-regulator bores are not automatically reamed. The valve body is inspected first and the appropriate repair is performed based on condition.
Application-correct TransGo components are used for the standard hydraulic update. When excessive bore wear is present, the appropriate Sonnax / TransGo oversized repair is used where required.
✔ TransGo T95996-5K Cooler Flow Bypass Delete
✔ STANDARD ON EVERY TWISTED STREET™ 6R80
The T95996-5K eliminates the factory thermostatic cooler bypass function and provides continuous cooler circuit flow.
✔ 6R80 / 10R80 Forward-Facing Transmission Cooler Adapter
✔ 6R80 / 10R80 Straight-Out -8AN Cooler Adapter
✔ Complete 6R80 / 10R80 External Cooler Kit with Adapters & Fittings
Additional external cooling is strongly recommended for towing, performance and severe-duty applications.
✔ Application-Correct Remanufactured Lockup Torque Converter
✔ Stock / Street Stall
✔ Correct Pilot & Mounting Configuration
✔ Converter Matched to Engine & Application
✔ Performance Converter Upgrades Available
Converter configuration varies by engine and application. The correct converter is selected for the ordered engine and transmission configuration.
✔ Lead Frame Failure
✔ Valve Body Wear
✔ Pressure Regulator Circuit Wear
✔ TCC / Converter Wear & Contamination
✔ Hydraulic Pressure Loss
✔ Internal Clutch Wear
✔ Pump & Bushing Wear
✔ Delayed Engagement
✔ Harsh / Erratic Shifting
✔ Heat-Related Wear
For maximum transmission life:
✔ Proper Transmission Cooling
✔ External Cooler Recommended for Towing & Performance Applications
✔ Cooler & Cooler Lines Must Be Clean / Flushed or Replaced
✔ Proper PCM / Transmission Calibration
✔ Correct Tire Size & Gear Ratio Calibration
✔ Proper Converter Lockup Strategy
✔ Monitor Transmission Temperature During Heavy Use
Aggressive tuning, excessive sustained heat, contaminated cooler systems or improper calibration can damage any automatic transmission.
Before installation, verify:
✔ Engine Misfires
✔ Crankshaft Endplay
✔ Flexplate Condition & Runout
✔ Converter Pilot Fitment
✔ Transmission Cooler Flow
✔ Cooler & Cooler-Line Contamination
✔ PCM / Transmission Calibration
✔ Tire Size & Gear Calibration
✔ Driveline / Driveshaft Condition & Angles
Vehicle-side or installation problems must be corrected before the transmission is placed into service.

This is not a mass-produced stock rebuild.
Every unit is built to order around the vehicle, engine, drivetrain, power level and intended use.
OEM+ Strength. Daily-Driver Manners. Built the Twisted Torque™ Way.
Most factory 6R80 applications were already making respectable horsepower and torque before any modifications.
As a general reference:
3.5L EcoBoost F-150
Approximately 365 HP / 420 LB-FT in common factory 6R80 applications.
5.0L Coyote F-150
Approximately 360–385 HP / 380–387 LB-FT in common factory 6R80 applications.
5.0L Coyote Mustang GT
Approximately 412+ HP / 390+ LB-FT depending on model year.
That means our Twisted Street™ 450 HP rating provides additional capacity over most stock 6R80 combinations, while remaining focused on daily-driven, OEM+ and mildly modified applications.
The 3.5L EcoBoost can gain substantial low-RPM torque with relatively simple tuning and modifications.
A vehicle may still be near our Street horsepower range while producing considerably more torque than the original factory combination.
If your EcoBoost is tuned, boosted beyond stock, used for heavy towing, or producing substantially increased torque, tell us before ordering. We may recommend stepping up to a Twisted Pro™ or Twisted Punisher™ 6R80 even if your peak horsepower number appears to fit the Street build.
