Built for Power, Precision, and Reliability
When the road demands more, Go Powertrain delivers. The Performance Transmissions are enhanced automatic transmission units specifically engineered for high-demand and high-output vehicle applications. Whether you're towing heavy loads, navigating tough off-road terrain, pushing limits on the track, or tackling heavy-duty work, our transmissions are built to handle it all—with strength, precision, and confidence.
Each unit in the RR Series is a custom-built solution, tailored to meet the unique demands of your specific application. We don’t believe in one-size-fits-all. Instead, we work to ensure that every transmission we ship is optimized for performance, durability, and longevity. The builders include high-energy friction materials, precision-tuned hydraulic systems, and hardened components, all designed to enhance shift quality and maintain integrity under extreme conditions.
We stand behind the performance transmissions with a 3-Year Unlimited Mileage Warranty, offering not just bold performance—but peace of mind. From the street to the strip, from job site to trailhead, give you the edge when you need it most.
Let your customers drive harder and farther.
