Twisted Torque Punisher™ 10R140 Performance Transmission | 750 HP / 800 LB-FT
The Twisted Torque Punisher™ 10R140 is the top of our gas 10R140 lineup.
This build is for the truck that's well past stock. Blower, turbo, aggressive cam, heads, tuning, or a high-output naturally aspirated Godzilla.
The Punisher starts with the increased clutch capacity of our Pro™, then steps up to the SunCoast Category 3 clutch, Pro-Loc valve body and pump package.
This isn't a Pro with a higher HP number. The pump and hydraulic system are upgraded with the clutch system to handle the additional power.
6.2L Gas V8: 385 HP / 430 LB-FT
2020–2022 7.3L Godzilla: 430 HP / 475 LB-FT
2023-Up 7.3L Godzilla: 430 HP / 485 LB-FT
Every transmission is built in-house and matched to the engine, power level and intended use.

Pro™ adds clutch capacity. Punisher™ adds the Pro-Loc valve body and pump system to support it.
━━━━━━━━━━━━━━━━━━━━━━
✔ Raybestos GPZ High-Performance Frictions
✔ Performance Steel Clutch Plates
✔ Extra-Capacity Clutch Setup
✔ High-Capacity E Clutch Assembly
✔ High-Capacity F Clutch Pack
✔ Clutch Clearances Set During Assembly
The stock gas 10R140 uses 4 E and 4 F frictions. Raybestos confirms the standard gas RGPZ-281 configuration is 4A / 5B / 5C / 5D / 4E / 4F.
The Punisher uses SunCoast's extra-capacity setup. The F clutch is increased from 4 to 5 frictions, adding 25% more clutch count in that pack. The high-capacity E assembly uses a new machined OE drum, piston and backing plate rather than simply stacking thinner clutches into a stock drum.
━━━━━━━━━━━━━━━━━━━━━━
✔ Updated C-D-F Drum Assembly
✔ Updated Bushing Retention Design
✔ C-D-F Feed Passages Checked During Assembly
✔ Early C-D-F Drum Design Eliminated
The early drum doesn't go back in. We use the updated C-D-F assembly and check the clutch feed circuits during assembly.

This is one of the big differences between Pro™ and Punisher™.
✔ SunCoast Pro-Loc Valve Body
✔ Increased Main Line Pressure
✔ Increased Clutch Clamping Force
✔ Increased Lockup Apply Pressure
✔ Faster Clutch Apply
✔ Increased Cooler Charge Pressure
SunCoast modifies overall main line pressure by as much as 60 psi and incorporates a pressure bypass above 420 psi. Their system also reduces the pressure required to fully stroke the clutch regulator and increases converter lockup apply pressure.
We're not just commanding more pressure through a stock worn valve body. The valve body and pump are part of the Punisher build.
━━━━━━━━━━━━━━━━━━━━━━
✔ SunCoast 10R140 Pump
✔ Increased Pump Volume
✔ Built To Work With The Pro-Loc Valve Body
✔ Supports Increased Main Line Pressure
✔ Supports Increased Clutch Apply Pressure
✔ Increased Cooler Charge
The pump is part of the Category 3 package. We aren't adding extra clutch capacity and relying on an unknown high-mileage pump to feed it.

✔ Complete Teardown & Cleaning
✔ New Bushing Kit
✔ New Seals & Gaskets
✔ New Sealing Rings
✔ New Bonded Pistons As Required
✔ Bearings & Torringtons Inspected & Replaced As Required
✔ New Transmission Filter

The 10R140 changed during the 2023 model year.
2020–2022 / Early 2023: LC3P-style main control
March 1, 2023-Up: PC3P-style main control
The later valve body changed hydraulic circuits, shift calibration and TCC operation and does not retrofit back to the earlier design. We identify the core before ordering/building the hydraulic package.
━━━━━━━━━━━━━━━━━━━━━━
✔ Solenoids Tested
✔ Solenoid Strategy Recorded
✔ Internal Harness Inspected & Tested
✔ TSS / ISSA / ISSB / OSS Speed Sensors Checked
✔ Transmission Temperature Circuit Checked
Anything that doesn't pass inspection gets replaced.

Torque Converter Not Included.
At this power level, a properly matched new or professionally remanufactured performance converter is required.
If the converter is not purchased from Twisted Torque, proof of purchase is required for warranty coverage.
The original used converter cannot be reused.
Converter selection is based on engine combination, camshaft, boost, vehicle weight, gearing and intended use.

Call us before ordering.
We're stopping the advertised gas 10R140 line at 750 HP / 800 LB-FT rather than throwing a bullshit four-digit horsepower rating on stock shafts and planetary hard parts.

Street™ fixes the known problems.
Pro™ adds clutch capacity.
Punisher™ adds the SunCoast Category 3 Pro-Loc valve body and pump package to control that added capacity at higher power.
Boosted, cammed or high-output Godzilla, this is the end of our gas 10R140 lineup.
Built in-house by Twisted Torque.
