Twisted Pro™ 700R4 performance transmission rated 500–550 HP.
The Twisted Pro™ 700R4 is our next step above the Street for cars and trucks making enough power to start putting real load on the factory 700R4 hard parts.
The Pro gets more clutch capacity, upgraded sprags, a reinforced input drum, HD planetary setup, additional pump upgrades and a stronger hydraulic calibration.
Built for 500–550 HP street and street/strip combinations that still need overdrive, converter lockup and normal automatic operation.
Every transmission is built in-house and matched to your engine, vehicle and intended use.
✔ High-Energy Performance Frictions
✔ New Performance Steels
✔ Extra-Capacity 3-4 Clutch Pack
✔ Increased Forward Clutch Capacity
✔ High-RPM 3-4 / Forward Clutch Spring Upgrade
✔ Clutch Clearances Set During Assembly
The 3-4 clutch is one of the weak areas in a 700R4. At the Pro level we increase clutch capacity and back it up with the pressure and hydraulic changes needed to keep it applied under load.
✔ Wide High-Energy Performance 2-4 Band
✔ Corvette 2nd Servo
✔ Performance 4th-Gear Apply
✔ Band & Servo Clearances Checked During Assembly
The Pro is calibrated for a quicker, firmer shift under throttle without making normal street driving unnecessarily harsh.
✔ New 29-Element Dual-Cage Forward Sprag
✔ New Low/Reverse Spring & Roller Assembly
✔ Reinforced Input Drum
✔ Heavy-Duty Hardened Sun Shell
✔ Hardened Stator Support
✔ Heavy-Duty 4-Pinion Steel Planetary Gear Set
✔ Input Shaft Inspected for Spline Wear, Twist & Damage
✔ Reaction Carrier, Sun Gear & Related Hard Parts Inspected
The Pro gets additional hard-part upgrades where the 700R4 starts taking a beating at higher power.
The factory input shaft is inspected and used only if it passes. Billet input shaft upgrades are available for higher-torque and severe-duty combinations.
✔ 10-Vane High-Capacity Pump
✔ New Pump Rotor & Slide
✔ New Pump Vanes
✔ Hardened Pump Rings
✔ New Pump Bushing
✔ Hardened Stator Support
✔ Performance Boost Valve & Pressure-Regulator Calibration
✔ Pump Clearances Checked & Set
The Pro pump is built to maintain stable line pressure at higher RPM and under heavier load.
We're not just cranking pressure up to make it shift hard. The goal is proper pressure rise and enough apply force to keep the clutch packs and band from slipping.
✔ Twisted Torque™ Performance Valve Body Calibration
✔ TV & Pressure-Rise Circuits Corrected
✔ Increased 3-4 Clutch Feed
✔ Performance Accumulator Calibration
✔ 2-3 & 3-2 Shift Timing Corrected
✔ Converter Lockup Circuit Checked & Calibrated
✔ Separator Plate & Checkball Setup Corrected
✔ Governor Calibrated for the Application
✔ TransGo, Superior and Sonnax performance corrections used as required
The Pro calibration is a step above Street with quicker apply, firmer shifts and better holding power under throttle while keeping normal automatic operation for street driving.
✔ Complete New Bushing Kit
✔ New Torrington Bearings
✔ New Thrust Washer Kit
✔ Wide Drum / Support Bushing Where Applicable
✔ Internal End-Play Checked & Set During Assembly
✔ Drum, Shaft & Planetary Clearances Checked
At this level we aren't putting worn bushings, bearings or thrust parts back into the transmission and hoping they live.
✔ 2300–2600 Stall Lockup Performance Torque Converter
✔ Street / Strip Friendly
✔ Good for Mild to Moderate Camshafts
✔ 4th-Gear Lockup for Highway Driving
✔ Higher Stall Options Available
Converter stall is matched to the combination.
Give us your engine, horsepower, cam specs, rear gear, tire size and vehicle use when ordering so we can match the converter correctly.
✔ Chevy 350 / 383 / 400 SBC Performance Builds
✔ Stroker Small-Blocks
✔ Mild Big-Block Chevrolet Builds
✔ Naturally Aspirated Performance Builds

✔ Monte Carlo / El Camino
✔ Chevelle / Nova
✔ Street Rods & Hot Rods
✔ Carbureted LS Swaps
✔ Street / Strip Cars
✔ Performance Overdrive Conversions
The TV cable on a 700R4 is NOT just a kickdown cable.
It controls transmission pressure in relation to throttle position. Incorrect cable geometry or adjustment can cause low line pressure, burned 3-4 clutches, band failure and rapid transmission damage.
Correct TV cable geometry and adjustment are mandatory.
Improper TV cable setup is an installation issue and is not covered as a transmission manufacturing defect.
The Pro isn't our Street transmission with a harder shift and a higher HP number.
The 29-element sprag, reinforced input drum, extra-capacity 3-4, HD planetary setup, upgraded pump and additional hydraulic work are there because that's where the load starts going as power increases.
Every Twisted Pro™ 700R4 is built in-house, pressure checked and tested before shipping.
