Built Specifically for Your Vehicle

The Twisted Street™ 200-4R is built for customers who want more than a basic rebuild.

Whether you're restoring a Grand National, cruising in a Monte Carlo SS, swapping overdrive into a Chevelle, or finishing an LS-powered restomod, every transmission is built to order for your specific application.

We don't believe in one-size-fits-all transmissions.

Before your transmission is assembled, we consider your:

✔ Engine Combination

✔ Horsepower

✔ Rear Gear Ratio

✔ Tire Size

✔ Vehicle Weight

✔ Intended Driving Style

This allows us to calibrate your transmission for the way you drive—not the way everyone else does.

Transmission Only. Lock-Up Torque Converter Included. Installation and conversion parts sold separately.

🔧 Twisted Street™ Build Features

✔ Twisted Torque™ Street Valve Body

Every valve body is calibrated in-house to provide:

• Clean, positive shifts
• Increased clutch holding power
• Improved line pressure
• Excellent street drivability

No harsh race-car shifts—just crisp, dependable performance.

✔ Blueprinted Pump Assembly

The pump is the heart of every automatic transmission.

Every pump is:

• Completely disassembled and inspected
• Fitted with a new pump bushing
• Upgraded with hardened pump rings
• Updated with a performance pressure regulator
• Built with a TV boost valve matched to your application
• Checked for proper clearances before final assembly

Because every vehicle is different, we select the proper boost valve—not simply install the same one in every transmission.

✔ High-Energy Clutch System

Built with:

• High-energy friction clutches
• Kolene steels
• Increased clutch capacity over stock

Designed to improve holding power while increasing durability for street performance and mild towing.

✔ Performance Servo & Wide Kevlar Band

These two components work together to improve 2nd gear holding power and shift quality.

Our Street™ builds receive a performance servo and wide Kevlar band selected for dependable street performance and long service life.

✔ Governor Calibrated for Your Vehicle

Unlike mass-produced rebuilds, we don't install the same governor in every transmission.

Governor calibration is matched to your:

• Engine combination
• Rear gear ratio
• Tire size
• Vehicle weight
• Driving style

This provides proper shift timing and overall drivability.

✔ Complete Internal Upgrade Package

Every Street™ build includes:

• Complete new bushing kit
• New bearings and thrust washers where required
• New sealing rings
• New lip seals throughout
• Hardened stator support

Every transmission is assembled with attention to hydraulic integrity and long-term reliability.

✔ Lock-Up Torque Converter Included

Includes a new lock-up torque converter with approximately a 1650 RPM stall speed, providing excellent street manners and comfortable highway cruising.

The factory dual-pattern bellhousing allows direct installation on most:

No adapter plate required for most GM applications.

Gear Ratios

✔ 1st – 2.74
