In 1915, James A. Allison founded the Speedway Team Company in Indianapolis to support his racing endeavors at the Indianapolis Motor Speedway. This venture would eventually evolve into Allison Transmission, now the world's largest manufacturer of fully automatic transmissions for medium and heavy-duty commercial vehicles. What began as a racing operation has transformed into a global leader in propulsion solutions, powering vehicles that build our cities, drive our commerce, and protect communities worldwide.
Today, Allison Transmission designs and manufactures a broad portfolio of conventional, electric hybrid, and fully electric propulsion systems that serve diverse industries including construction, defense, emergency services, mining, oil and gas, public transit, and more. With headquarters in Indianapolis, Indiana, and operations spanning the globe, Allison's products are specified by more than 2,500 of the world's leading vehicle manufacturers and are known for unmatched quality, reliability, and durability. The company continues its legacy of innovation, now spanning over a century, by developing advanced transmission technologies that improve the way the world works while maintaining its commitment to engineering excellence and customer-focused solutions.
