🔥 TWISTED TORQUE PRO™ 10R140 DIESEL

2020-UP FORD 10R140 • 6.7L POWER STROKE DIESEL

UP TO 750 HP / 1,500 LB-FT

TUNED • HEAVY TOWING • PERFORMANCE • HARD-WORKING DIESEL

The Twisted Torque Pro™ 10R140 Diesel steps beyond our Street™ build for modified 6.7L Power Stroke trucks making more power, towing heavier and working the transmission harder.

We start with the diesel-specific GPZ clutch system used in our Street™, then increase clutch capacity where the 10R140 needs it, step up the C-D-F and E-clutch feed hardware, and build the valve body in-house with Sonnax hydraulic corrections and our Twisted Torque performance calibration.

This isn't a stock rebuild with a shift kit thrown in it.

Every transmission is built in-house and matched to your truck, power level and intended use.

🔧 PRO™ DIESEL CLUTCH SYSTEM

✔ Raybestos GPZ Performance Frictions

✔ Diesel-Specific Steel Configuration

✔ 6-Friction C Clutch

✔ 6-Friction D Clutch

✔ Expanded-Capacity E Clutch

✔ Expanded-Capacity F Clutch

✔ Performance Clutch Clearances Set During Assembly

The Pro™ retains the higher-capacity diesel C and D clutch configuration and steps beyond Street™ with additional capacity in the E and F clutch sections.

The added clutch capacity gives us more friction area to handle increased torque, heavier towing and tuned applications.

━━━━━━━━━━━━━━━━━━━━━━

🔧 UPDATED C-D-F DRUM

STANDARD ON PRO™

✔ New Updated C-D-F Drum

✔ Updated Feed Bushing Design

✔ C-D-F Feed Passages Checked

✔ C, D & F Feed Circuits Checked

We're not waiting for a questionable early C-D-F drum to fail.

Pro™ receives the updated C-D-F drum as part of the build.

━━━━━━━━━━━━━━━━━━━━━━

🔧 UPDATED E-CLUTCH FEED SYSTEM

STANDARD ON PRO™

✔ Updated E-Clutch Feed Hub

✔ Updated E-Clutch Feed Shim / Hardware

✔ E-Clutch Feed Circuit Checked

✔ Feed Surfaces Checked For Leakage

✔ E-Clutch Drum Inspected

The E-clutch feed system is addressed during every Pro™ build to maintain positive clutch apply under increased load.

━━━━━━━━━━━━━━━━━━━━━━

🔧 TWISTED TORQUE PRO™ PERFORMANCE VALVE BODY

The Pro™ valve body is built and calibrated in-house.

We aren't buying somebody else's performance valve body and bolting our name to it.

✔ Complete Valve Body Disassembly

✔ Complete Cleaning

✔ Critical Hydraulic Circuits Vacuum Tested

✔ Clutch Control Valve Bores Inspected

✔ Valve Bores Sized / Corrected As Required

✔ Main Pressure Regulator Circuit Checked

✔ TCC Priority Circuit Checked

✔ TCC Signal Damper Circuit Checked

✔ LPC Signal Damper Circuit Checked

✔ Latch Valve Circuits Checked

✔ Solenoids Individually Tested

✔ Solenoid Strategy Recorded

✔ Twisted Torque Performance Hydraulic Calibration

Sonnax specifically provides the 105740-BST bore-sizing tool for 10R140 clutch-control valve bores damaged by solenoid movement, allowing the bores to be smoothed and checked for proper valve clearance during rebuilding.

━━━━━━━━━━━━━━━━━━━━━━

🔧 SONNAX SOLENOID STABILIZATION

STANDARD PRO™ UPGRADE

✔ Sonnax Solenoid Stabilization Clip Inserts

✔ Sonnax Solenoid Stabilization Retainer — Where Applicable

✔ Solenoid Alignment Checked

✔ Clutch Control Valve Movement Checked

The heavy linear-force solenoids in the Ford 10-speed family can lose proper support as the OE retaining system wears or collapses.

Sonnax developed the stabilization system to prevent solenoid movement that can cause loss of control pressure, poor shifts, clutch damage and valve-body casting damage. The updated retainer provides 32% more casting-to-solenoid support area and incorporates a positive stop to resist collapse.

━━━━━━━━━━━━━━━━━━━━━━

🔧 MAIN PRESSURE REGULATOR CIRCUIT

✔ Main Pressure Regulator Bore Vacuum Tested

✔ Regulator Valve & Bore Inspected

✔ Sonnax Main Pressure Regulator Repair As Required

✔ Oversized Sonnax Regulator & Bore Reconditioning As Required

For applicable early-design valve bodies, severely worn regulator bores can be reconditioned and fitted with the Sonnax 105740-20K oversized regulator system.

Its extended valve spool provides additional sealing area and improved valve stability while the O-ringed end plug prevents critical signal-pressure leakage.

The Sonnax repair restores hydraulic integrity. Twisted Torque's performance calibration is performed separately during the build.

━━━━━━━━━━━━━━━━━━━━━━

🔧 TCC PRIORITY CIRCUIT

✔ TCC Priority Valve & Bore Inspected

✔ TCC Priority Circuit Vacuum Tested

✔ Sonnax Oversized TCC Priority Valve Installed As Required

Wear in this circuit can leak secondary line and TCC signal pressure to exhaust, reducing converter feed pressure and contributing to overheated fluid and converter clutch problems.

Where required, the bore is reconditioned and fitted with the Sonnax 105740-76K oversized TCC priority valve.

The Sonnax replacement uses an outboard spool 250% longer than OE for improved sealing and stability.

━━━━━━━━━━━━━━━━━━━━━━

🔧 LATCH VALVE SYSTEM

✔ Both Latch Valves Inspected

✔ Latch Valve Bores Checked

✔ Latch Valve Stems Inspected

✔ Sonnax Stem Repair Installed As Required

✔ Oversized Latch Valve Repair Installed As Required & Where Applicable

The 10R140 uses two latch valves. Sonnax has documented stem damage caused by contact between the valve spring stem and retaining-clip exhaust opening, which can interfere with valve travel and contribute to clutch failure.

The current 105740-50K repair reinforces this area and prevents recurring stem and spring damage.

━━━━━━━━━━━━━━━━━━━━━━

🔧 TCC & LPC SIGNAL CONTROL

✔ TCC Signal Damper Circuit Checked

✔ LPC Signal Damper Circuit Checked

✔ Sonnax TCC Damper Repair As Required & Where Applicable

✔ Sonnax LPC Damper Repair As Required

The LPC signal damper repair addresses pressure-control leakage that can contribute to excessive line pressure and harsh shifting.

━━━━━━━━━━━━━━━━━━━━━━

⚠️ 2023-UP PC3P VALVE BODY

Ford changed the 10R140 valve-body design.

WE DO NOT TREAT EVERY 10R140 VALVE BODY THE SAME.

2023-up units with the PC3P-design casting are identified before machining and serviced using the correct generation-specific parts and procedures.

Several Sonnax early-design repairs specifically do not fit the 2023-later PC3P valve body, including:

✔ 105740-12K Main Pressure Regulator

✔ 105740-20K Oversized Main Pressure Regulator

✔ 105740-75K Oversized Latch Valve

✔ 105740-07K TCC Signal Damper

Twisted Torque identifies the valve-body generation before machining or hydraulic repair.

━━━━━━━━━━━━━━━━━━━━━━

🔧 PRO™ PUMP & PRESSURE SYSTEM

✔ Pump Completely Disassembled

✔ Pump Body Inspected

✔ Pump Cover Inspected

✔ Pump Gears Inspected

✔ Pump Clearances Checked

✔ New Pump Bushing

✔ Pressure Regulator System Checked

✔ Pump Feed Circuits Checked

✔ Converter Feed Circuit Checked

✔ Cooler / Lubrication Feed Circuits Checked

✔ Pump Replaced If Out Of Specification

✔ Twisted Torque Pro™ Hydraulic Calibration

We're not going to advertise a made-up fixed pressure increase.

The Pro™ pump and valve body are built together to maintain the hydraulic volume, clutch apply and converter control required by the increased-capacity clutch system.

━━━━━━━━━━━━━━━━━━━━━━

🔧 COMPLETE PRO™ OVERHAUL

✔ Complete Teardown & Cleaning

SOLENOID STRATEGY INFORMATION IS RECORDED WITH THE TRANSMISSION FOR INSTALLATION AND PROGRAMMING.

━━━━━━━━━━━━━━━━━━━━━━

⚠️ TORQUE CONVERTER NOT INCLUDED

A new or professionally remanufactured 10R140 diesel torque converter is required.

THE ORIGINAL USED TORQUE CONVERTER CANNOT BE REUSED.

For Pro™ applications, the replacement converter must be properly matched to the vehicle's power level, torque output and intended use.

If the converter is purchased elsewhere, proof of purchase for the replacement converter is required for warranty coverage.

Stock replacement and performance diesel converters are available separately.
