There's no question that Delta Transmission in Antioch has staying power. In business since 1958, the shop boasts over 40 years combined experience in automotive repair. Owner Chester Kniss' fascination with working on cars began when he was a child. He obviously never outgrew this “car thing” and was able to take what he loved to do and turn it into a successful career. He still enjoys what he does, and it shows.

As the name implies, Delta Transmission specializes in transmission service, repair and custom rebuilds. Whether your transmission just needs to be serviced or whether a complete re-do is called for, they're the experts. They also do brake work on most vehicle makes and models.

Delta Transmission has remained small and family-owned throughout its history. Their core values remain the same; to give honest, professional service at a fair price. They're never too busy to answer questions or explain a procedure and enjoy sharing their knowledge and educating their clients.
