Company History and Business Evolution

Allison Transmission traces its origins to 1915 when James A. Allison founded the Allison Experimental Company in Indianapolis to support the fledgling aviation industry. The company quickly became known for precision machining and engineering, producing aircraft engines during World War I. In 1929, the company was acquired by General Motors and renamed the Allison Division. Over the following decades, Allison pioneered the first automatic transmission for heavy trucks in 1948, revolutionizing the commercial vehicle industry. Throughout the 1950s and 1960s, the company expanded its product line to include transmissions for military vehicles, notably the M1 Abrams tank, and introduced the world’s first fully automatic transmission for transit buses. The 1970s and 1980s saw Allison solidify its dominance in the transit and motorhome markets, while also venturing into off-highway applications for mining and construction. A pivotal moment came in 2007 when the Carlyle Group and Onex Corporation acquired Allison Transmission from General Motors, making it an independent entity. This move allowed the company to focus more aggressively on global expansion and technological innovation. In 2010, Allison Transmission returned to the public market with an initial public offering on the New York Stock Exchange (NYSE: ALSN). Since then, the company has made strategic acquisitions, including the purchase of Voith’s bus transmission business in 2013 and the integration of electric axle technology from AxleTech in 2021. Recent milestones include the launch of the eGen Series electric propulsion systems for transit buses and delivery trucks, as well as the introduction of the FuelSense 2.0 software that optimizes transmission shift patterns to deliver up to 6% fuel savings. Allison’s roadmap also includes a partnership with Wrightbus to supply eGen Power axles for zero-emission buses in the UK, and a multi-year contract with the U.S. Department of Defense to supply transmissions for next-generation armored vehicles. Today, the company employs approximately 3,700 people worldwide and generates annual revenues exceeding $2.5 billion. Its global service network includes more than 1,600 independent distributors and dealers, ensuring that customers receive timely support and parts anywhere in the world.
