The story

Founded by Anthony A. Martino in 1957.1

Anthony A. Martino started repairing automatic transmissions from leased space in an Esso shop in Philadelphia. In 1957, he founded the Anthony A. Martino Company, or AAMCO in Philadelphia, under the name AAMCO Auto and Truck Repair. This name was chosen not only to reflect the initials of the founder, but also to make it appear higher in the Yellow pages listings of the day. Along with partners Richard Silva and Walter D'lutz', Martino opened several other shops in the Philadelphia area. Owing to the complexity and failure rate of automatic transmissions of the day, Martino quickly decided to drop the "Auto and Truck Repair", and focus solely on transmissions, where the company would stay focused until 2007.

In 1962, Robert Morgan approached Martino with the concept of a national chain of transmission repair stores branded as AAMCO. Martino was receptive to the idea, and the shops operated in cooperation with Silva and DeLutz were rebranded as AAMCO. The first franchise was not sold until 1963, when an AAMCO shop was opened by Ivan and Jack Ginninger in Newark, New Jersey.

In March 2006, AAMCO merged with Cottman Transmission, and American Capital purchased AAMCO and moved the headquarters from Philadelphia to nearby Horsham, Pennsylvania.

Owing in part to the increased reliability of automatic transmissions, and thus the lengthened repair cycle, in the mid-2000s, the company rebranded to AAMCO Transmissions and Total Car Care. Today, AAMCO is the world's largest franchisor of transmission specialists and car repair shops, operating over 600 franchise stores in the United States, Canada.

AAMCO is also known for its distinctive television and radio commercials, which end with a voice saying "AAMCO, double-A [car horn beeps twice] M-C-O."

The company has made heavy use of celebrity spokespeople in its advertising, and was one of the first to use a celebrity spokesperson in a television ad. Zsa Zsa Gabor was the company's first paid spokesperson.
