Ford 5R110W Street Diesel Performance Transmission | 6.0L & 6.4L Power Stroke | 2003–2010

TWISTED TORQUE STREET SERIES | 450 HP / 650 LB-FT TORQUE

The Twisted Torque 5R110W Street Diesel is built for stock-powered 6.0L and 6.4L Power Stroke trucks. Daily drivers, tow rigs, work trucks and Super Dutys that put in long hours hauling and pulling trailers.

Rated up to 450 horsepower and 650 lb-ft of engine torque, our Street build retains the factory clutch configuration while upgrading friction materials, replacing worn internals and addressing known 5R110W factory problems.

Every transmission starts with a complete teardown. We inspect the case, pump, drums, shafts and planetary assemblies before rebuilding it with new clutches, steels, bushings, seals and all-new internal electronics.

STREET DIESEL BUILD SPECIFICATIONS

CLUTCHES & STEELS

• New Raybestos performance friction clutches — application dependent
• New steel clutch plates throughout
• Forward, Direct, Intermediate, Overdrive, Coast & Low/Reverse clutch packs rebuilt
• New bonded apply pistons and seals
• Clutch drums inspected for wear and damage
• Clutch pack clearances measured and set to specification

FACTORY UPGRADE: Raybestos performance frictions are selected for improved heat resistance and clutch holding characteristics during daily driving, towing and hauling.

PUMP & PRESSURE REGULATOR

• Complete pump teardown, inspection and reconditioning
• Updated hardened steel pressure-regulator valve
• Pressure-regulator bore inspected and repaired as needed
• Converter clutch regulator circuit inspected and updated as required
• TransGo pump vent correction
• New pump bushings
• Pump gears, alignment and clearances checked

FACTORY UPGRADE: The updated pressure-regulator valve and pump repairs address known sticking valves, pressure loss and pressure spikes that can lead to slipping and burned clutches.

VALVE BODY & SHIFT CONTROL

• Complete valve-body teardown and cleaning
• TransGo 5R110W shift correction updates
• Updated metal pressure-switch plugs with O-ring seals
• Converter clutch control valve inspected
• Shift valves, manual valve and separator plate inspected
• Valve bores checked for wear and leakage
• Valve body checked for proper valve movement

FACTORY UPGRADE: The factory pressure-switch plugs can crack or leak, causing clutch apply-pressure loss. Updated metal plugs and seals help prevent these failures.

ELECTRONICS & SOLENOIDS — ALL NEW

• New shift-pressure control solenoids
• New electronic pressure-control solenoid
• New torque converter clutch solenoid
• New internal transmission wiring harness
• New transmission fluid temperature sensor
• Input, turbine and output speed sensors inspected and replaced as needed
• Electrical connectors and solenoid operation checked

We replace the internal solenoids and wiring harness rather than reuse aging electronics in a freshly rebuilt transmission.

DRUMS, BUSHINGS & INTERNAL UPDATES

• New transmission bushings throughout
• New seals, gaskets and O-rings
• Updated Forward drum sealing rings
• Updated one-piece Direct drum bushing
• Updated heavy-duty Low/Reverse retaining ring
• Factory input and intermediate shafts inspected
• Planetary gear assemblies and one-way clutches inspected
• Thrust bearings and washers inspected and replaced as needed
• Transmission endplay checked and set to specification
• New transmission filter

FACTORY UPDATES: The updated Forward sealing rings help reduce pressure leakage, while the one-piece Direct drum bushing improves drum support.

The heavy-duty Low/Reverse retaining ring helps prevent the factory ring from dislodging and damaging the transmission case.

OEM-STYLE TORQUE CONVERTER — INCLUDED

• Stock OEM-style diesel torque converter
• Factory stall speed
• Factory-style lockup operation
• Matched to the 6.0L or 6.4L Power Stroke application

Billet-cover performance converter upgrades are available for customers needing additional converter strength.

HORSEPOWER & TORQUE RATING

450 HP | 650 LB-FT TORQUE

Designed for factory-powered and mildly modified Power Stroke trucks operating within the advertised horsepower and torque limits.

Factory engine ratings for reference:

• 6.0L Power Stroke — up to 325 HP / 570 LB-FT
• 6.4L Power Stroke — up to 350 HP / 650 LB-FT

Both horsepower and torque must remain within the Street build's limits. Trucks with aggressive tuning, larger injectors, upgraded turbos or higher torque output should consider our Pro or Punisher Diesel builds.

TRANSMISSION TUNING & CALIBRATION

The Ford 5R110W is electronically controlled, and proper tuning plays an important role in shift timing, clutch apply pressure and torque converter lockup. Our transmissions are built to work with factory-compatible programming, but trucks running aftermarket engine tunes or modified power levels may require transmission tuning adjustments.

Excessive line pressure, aggressive shift settings or improper converter lockup can damage even an upgraded transmission. Please advise our team of any existing tuning or engine modifications before ordering. Custom tuning is not included.
