Circle D Transmission

Circle D Transmission has been serving the greater Houston area since 1976. We help guide people just like you with their transmission repair by providing an up-front and honest approach, a professional diagnosis and accurate & timely repairs all backed by our outstanding reputation. We also offer rear differential repair, transfer case replacement, clutch replacement and preventative transmission maintenance. 

Circle D Transmission also has a performance division that specializes in GM and Ford 6 speed automatic transmissions - 6L80, 6L90 and 6R80. Our goal was to take the factory transmission and transform it so that it is able to handle the horsepower revolution present today.  We offer two different options, you can ship your transmission to us for a custom CDT rebuild or you can purchase a CDT Rebuild Kit and have a professional install it for you. Multiple kits are available to choose from for different horsepower levels.
