About Circle D Transmission

When you choose Circle D for your 6L90 transmission rebuild, you can be confident that we’ll get the job done right. Our team combines decades of industry knowledge and experience with a passion for the latest technology, development, and research, making us innovators and leaders when it comes to transmission rebuilds. Since our founding in 1976, we’ve specialized in Ford and GM rear-wheel drive high performance transmissions. Whether it’s for a custom show vehicle or street and strip, we can get your horsepower to the pavement where it belongs.

What sets Circle D apart from our competitors is that transmission rebuilds aren’t just a business for us—they’re also our passion. Each of our team members loves what they do and it shows in our service. Even before you submit your order for a 6L90 transmission rebuild, our experts are here to answer all of your questions, and we’ll continue to provide support and assistance once your transmission rebuild is complete.

 Over the years, the Circle D business has evolved from its humble beginnings as a two bay shop into the premier destination for Houston horsepower junkies seeking transmission rebuilds. These days, you’ll also find our high performance transmission parts and rebuild services for transmissions available for purchase on our website, giving customers from across the country access to the same 6L90 performance rebuilds as Houston locals. 

Despite our growth, we’re still a small, family-owned business and we’re thrilled to know that our transmission rebuilds and parts are being used in cars near and far.
