Automatic Transmission Rebuilders Association

Founded in 1954, the Automatic Transmission Rebuilders Association (ATRA) is an international trade association for the professional automatic transmission repair industry. Located in Oxnard, California, ATRA has over 2000 members worldwide who consist of repair specialists, students, schools, and suppliers.


Why We Think ATRA Membership Is Important

Technicians become ATRA-certified by studying and passing ATRA exams in three areas of transmission diagnosis and repair. They must have at least two years of experience in the business and must pledge to follow the ATRA member code of ethics and comply with the "golden rule" warranty. Members receive a great deal of support from ATRA, which they pass on to their customers.
