🔥 Twisted Street™ 200-4R Performance Overdrive Conversion Package

Rated 350–450 HP

Built for Classic Muscle Cars • G-Bodies • Restomods • Street Rods

Reliable Overdrive • Firm, Positive Shifts • Built the Twisted Torque™ Way

Built Specifically for Your Vehicle

The Twisted Street™ 200-4R is built for customers looking for 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 combination.

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 build and calibrate your transmission for the way YOU drive—not the way everyone else does.

Transmission includes NEW Lock-Up Torque Converter.

Installation and conversion accessories available separately or as a complete conversion package.
