Allison Transmission was founded by James A. Allison when he and three business partners built the Indianapolis Motor Speedway. This track held the first Indianapolis 500 race in 1911.
The company began producing machine parts during World War I. After the war, the company changed course again, this time to aviation engineering.
Today Allison Transmission builds automatic transmissions for medium and heavy-duty commercial vehicles and hybrid-propulsion systems for buses. The company serves customers in more than 80 countries in the Americas, Europe, Africa, and Asia.
Allison Transmission trades publicly on the New York Stock Exchange under the ticker symbol ALSN, is #996 in the Fortune 1000, has 2,700 employees, and had $2.14 billion in revenue in 2014.
In May 2022, the company introduced a completely electric axle for first responders’ vehicles.
Allison Transmission maintains a corporate office in Indianapolis, Indiana.
