Founded in 1915 by automotive pioneer James A. Allison, the company originally supplied components to the early automotive and aviation industries before developing its first automatic transmission in the early 20th century. Over subsequent decades, Allison Transmission expanded its engineering capabilities and production footprint, becoming part of General Motors in 1929 and operating as a key powertrain business unit until its initial public offering in 2007. Since then, the company has pursued growth through new product introductions, strategic partnerships and investments in electric and hybrid technologies.
Today, under the leadership of President and Chief Executive Officer David Graziosi, Allison Transmission maintains manufacturing facilities in North America, Europe, India, China, Brazil and Mexico. The company’s global sales and service network spans more than 100 countries, supported by regional technical centers and a network of factory-authorized distributors. Through ongoing research and development efforts, Allison continues to advance powertrain innovation to serve evolving customer demands in a diverse set of transportation markets.
