What is ATRA?

Founded in 1954, the Automatic Transmission Rebuilders Association (ATRA) is an international trade association for the professional automatic transmission repair industry.

Located in Oxnard, CA, the ATRA has 2300+ members worldwide. Our membership consists of more than 2000 rebuilders, technical subscribers, students and schools, supporting the training, research and improvements to vehicles driven by the motoring public.

Every ATRA Rebuilder Member must adhere to ATRA’s Code of Ethics…ATRA’s standards for providing honest, professional service. So, when you take your car to an ATRA Rebuilder Member, you’re assured of polite, professional service, at an honest price.

And not just automatic transmission repair: most ATRA members also provide diagnostic and repair service for manual transmissions, clutches, differentials, driveshafts, drive axles, and transfer cases. Which all boils down to one inescapable conclusion: If your car starts but doesn’t move, you need to call your nearby ATRA Rebuilder Member…right away!
