About Circle D Transmission

Why choose Circle D for your 8L90 transmission rebuild? The answer is simple: we’ll get the job done right. Our team has specialized in Ford and GM rear-wheel drive high performance transmissions since 1976.

Transmission rebuilds aren’t just our business—they’re also our passion. We love what we do and it shows in our service. 

The Circle D business has expanded over the years, from our beginnings as a two-bay shop to becoming the go-to destination for Houston locals who need transmission rebuilds. These days, you’ll also find our high-performance transmission parts and rebuild services for transmissions available for online purchase.

As a small, family-owned business, we’re thrilled to know that our transmission rebuilds and parts are being used in vehicles near and far. Contact our team today to learn more about our 8L90 performance transmission rebuild services or fill out our performance questionnaire to start the process.
