AAMCO Transmissions is geared for transmission repair. The company is a leading franchiser of transmission fix-it facilities, with about 900 independently owned and operated shops throughout the US, Canada, and Puerto Rico. In addition to transmission work, AAMCO locations provide automotive cooling and electrical system repairs, as well as other general maintenance services. The company was established in 1963 by Robert Morgan and MAACO founder Anthony Martino. Today it operates alongside sister franchiser Cottman Transmission under holding company American Driveline Systems, itself a subsidiary of investment firm American Capital.
