About Circle D Transmission
Circle D has been a leader in the transmission industry since 1976, specializing in GM and Ford rear-wheel drive high performance transmissions. We stay at the forefront of our industry by keeping up with the latest technology, research, and development.
We entered the parts business after we purchased a Gen 5 Camaro for research and development on the 6L80 transmission for performance purposes. Our team’s goal was to transform the factory transmission to allow it to handle today’s horsepower revolution. Along the way, we received countless requests from other horsepower junkies asking about purchasing Circle D Transmission’s revolutionary performance kits for the 6L80.
Our performance parts retail service allows us to offer customers everywhere the same high quality 6L80 rebuild kits and performance parts that we use for our local customers. As a small, family-owned business, we’re thrilled to know that our transmission rebuild kits and parts are being used throughout the United States and even around the globe.
