🔥 Twisted Street™ 200-4R Overdrive Conversion Package

Rated 350–450 HP

Complete Street Overdrive Package for Classic GM Applications

Swapping a TH350, TH400, Powerglide or other 3-speed to overdrive? The Twisted Street™ 200-4R Conversion Package gives you our upgraded Street 200-4R, new lock-up converter and the main parts needed to complete the conversion.

Our Street 200-4R is a stock-based build with the factory problem areas addressed. We upgrade the friction material, rebuild and update the pump, install a mild TransGo or Superior shift kit and go through the valve body and hydraulic system.

Built for street use with a clean, firm shift. No race calibration and no unnecessary billet parts.

Rated 350–450 HP depending on engine torque, vehicle weight and intended use.

NEW 1650 RPM stock-stall lock-up torque converter included.

🔒 NEW 1650 RPM LOCK-UP CONVERTER

Stock stall works well for mild street combinations and keeps normal around-town driving and highway manners.

Higher-stall converters are available if your engine combination calls for one.

⚠️ 200-4R TV CABLE SETUP

The TV cable is not a kickdown cable.

It controls line pressure and shift operation. Incorrect TV cable adjustment or incorrect carburetor/throttle geometry can burn up a 200-4R.

That's why the conversion package includes the TV cable and geometry correction components for the application.

TV cable geometry and adjustment must be set correctly during installation.

⚡ 4TH-GEAR CONVERTER LOCK-UP

The package includes a simple 4th-gear lock-up wiring setup.

The converter can be wired for automatic lock-up in 4th gear or incorporated into a brake-switch/manual-switch setup depending on the vehicle.

BEFORE WE BUILD IT

We need:

• Year / Make / Model
• Engine
• Estimated horsepower
• Rear gear ratio
• Rear tire size
• Carburetor or EFI
• Naturally aspirated or power adder
• Intended use

This lets us make sure you're getting the right transmission and conversion components for the car.

GM MULTI-PATTERN BELLHOUSING

The 200-4R factory multi-pattern case fits many:

✔ Chevrolet

✔ Buick

✔ Oldsmobile

✔ Pontiac

Always verify application before ordering.

200-4R GEAR RATIOS

1st: 2.74

2nd: 1.57

3rd: 1.00

4th: 0.67 Overdrive

The 0.67 overdrive is a big advantage when converting an older 3-speed car. You keep a good 2.74 first gear and get the lower highway RPM of overdrive.
