🔧 TWISTED STREET™ 700R4 PERFORMANCE TRANSMISSION

GM 700R4 / Hydraulic 4-Speed Overdrive

UP TO 400 HP

DAILY DRIVER • STREET PERFORMANCE • CRUISERS • TRUCKS • OVERDRIVE SWAPS

The Twisted Street™ 700R4 is built for stock and mildly modified GM cars and trucks making up to 400 HP.

The 700R4 is a good street transmission when it's built and set up right, but there are a few areas we don't leave stock. The 3-4 clutch, 2-4 band, sun shell, sprag, pump and hydraulic system all get attention during the build.

We upgrade those areas, correct the known hydraulic issues and set the transmission up for the vehicle it's actually going into.

This is not a stock rebuild with a shift kit thrown in it.

Every transmission is built in-house and matched to your engine, vehicle and intended use.

🔧 WHAT WE UPGRADE

CLUTCHES & STEELS

✔ High-Energy Performance Frictions

✔ New Performance Steels

✔ Increased 3-4 Clutch Capacity

✔ Clutch Clearances Set During Assembly

The 3-4 clutch is one of the weak areas in a 700R4. More clutch capacity doesn't mean much if the clearance and apply pressure aren't right, so we address both during the build.

2-4 BAND & SERVO

✔ Heavy-Duty Wide 2-4 Band

✔ Corvette 2nd Servo

✔ Increased Band Apply

The wider band gives us more holding area, and the Corvette servo increases apply force. That gives the transmission a cleaner 1-2 shift and better holding power in 2nd without making a street truck or car shift like a race transmission.

SPRAGS & HARD PARTS

✔ New Forward Sprag

✔ Hardened Heavy-Duty Sun Shell

✔ Hardened Stator Support

✔ Low/Reverse Roller Clutch Inspected and Replaced as Needed

✔ Input Drum Inspected for Wear and Bushing Fit

✔ Front and Rear Planetaries Inspected for Pinion, Gear and Thrust Wear

✔ Reaction Carrier and Sun Gear Inspected

The factory sun shell and forward sprag are two areas we don't want to gamble with in a performance build. The Street gets a new forward sprag and upgraded hardened sun shell instead of putting questionable used parts back in it.

⚙️ 10-VANE PUMP

Every Twisted Street™ 700R4 gets a 10-vane pump setup.

✔ 10-Vane Pump

✔ Pump Completely Disassembled and Inspected

✔ Rotor, Slide and Vanes Checked

✔ Pump Clearances Checked and Set

✔ Pump Rings Inspected and Replaced as Needed

✔ New Pump Bushing

✔ Pressure Regulator System Checked and Corrected

✔ Boost Valve Calibrated for the Build

The pump is the heart of the hydraulic system. If the pump and pressure-regulator circuit aren't right, the clutches and band aren't going to stay applied no matter how expensive the friction material is.

We build the pump for proper pressure rise and clutch/band apply, not just higher pressure for the sake of making it shift hard.

⚙️ VALVE BODY & SHIFT CALIBRATION

The valve body is completely gone through and recalibrated during the build.

✔ Performance Shift Calibration

✔ TV & Pressure-Rise Circuits Checked and Corrected

✔ 3-4 Clutch Feed Addressed

✔ Accumulator Circuits Recalibrated

✔ 2-3 and 3-2 Shift Timing Checked

✔ Converter Lockup Circuit Checked

✔ Separator Plate and Checkball Setup Checked

✔ Governor Inspected and Set Up for the Application

We use proven TransGo, Superior and other professional hydraulic corrections as needed for the year and valve body we're building.

We're not trying to make a Street transmission bang every gear.

The goal is good pressure, positive clutch and band apply, clean shifts and less slip. That's what keeps a 700R4 alive on the street.

🔩 BUSHINGS, BEARINGS & INTERNAL CLEARANCES

✔ Complete New Bushing Kit

✔ New Pump Bushing

✔ Drum and Case Bushing Fit Checked

✔ Bearings and Thrust Washers Inspected and Replaced as Needed

✔ Internal End-Play Checked and Set During Assembly

A worn bushing doesn't get reused because it "looks okay." Bushing fit, drum support and end-play matter in these units, especially once you start adding power and RPM.

🔥 INCLUDED TORQUE CONVERTER

✔ 1650 Stall Torque Converter Included

✔ Built for Stock and Mild Performance Engines

✔ Good Street Manners

✔ Smooth Engagement

✔ Good Choice for Cruisers, Daily Drivers and Light-Duty Trucks

Running a cam, different rear gear or something other than a basic stock/mild combination?

Give us the engine, cam specs, rear gear, tire size and vehicle use so we can match the converter to the vehicle instead of guessing at stall speed.

🚗 GOOD FOR

✔ Chevy 305 / 350 / 383 Small-Block Builds

✔ Mild Big-Block Chevrolet Builds

✔ Camaro / Firebird

✔ Corvette

✔ C/K Series Pickups

✔ Monte Carlo / El Camino

✔ Chevelle / Nova

✔ Classic GM Cars and Trucks

✔ Street Rods & Hot Rods

✔ Carbureted LS Swaps

✔ TH350 / TH400 to Overdrive Conversions

✔ Daily Drivers & Cruisers

Fitment varies by year, spline count, speedometer setup and application. We verify the transmission configuration when you order.

⚠️ TV CABLE SETUP MATTERS

The TV cable on a 700R4 is NOT just a kickdown cable.

It controls transmission pressure in relation to throttle position. If the cable geometry or adjustment is wrong, the transmission can run with low pressure and burn the 3-4 clutch and 2-4 band very quickly.

Correct TV cable geometry and adjustment are mandatory.

Incorrect setup can cause:

• Low line pressure

• Soft or slipping shifts

• Burned 2-4 band

• Burned 3-4 clutches

• Incorrect shift timing

• Excessive heat

• Transmission failure

Improper TV cable geometry or adjustment is an installation issue and is not covered as a transmission defect.

If you're using an aftermarket carburetor or throttle-body setup, make sure you have the correct TV cable bracket and geometry correction for that application.
