Allison Transmission is an American manufacturer of commercial-grade automatic transmissions and hybrid propulsion systems.

Allison began in 1909, when James A. Allison, along with three business partners, helped finance and build the Indianapolis Motor Speedway. In 1911, the first 500-mile race in Indianapolis took place on the new Allison circuit. In addition to funding several racing teams, Jim Ellison created his own racing team in 1915 and quickly gained a reputation for his work on racing cars and automotive vehicles in general.

When World War I began, Allison suspended the race, and Allison Experimental Company began processing parts, tools and wizards for the engine of the Liberty aircraft, the main powerplant used in US military operations. After the war, Allison entered the car in the 1919 Indy 500 and won. It was the last race in which the Ellison team participated, when he drew the attention of his company to aviation technology. The company's expertise in aviation was a major factor in the decision of General Motors to buy the company after the death of Jim Ellison in 1928.

Shortly after the sale of General Motors in 1929, Allison engineers began work on a 12-cylinder engine to replace outdated Liberty engines. The result was a V1710 12-cylinder aircraft engine, thanks to which the company, now known as the Allison Engine Company, became the main force in aviation.

By the end of World War II, General Motors formed the Allison Transmission company to use the experience of engineers to work in a new field — power transmissions for tracked military equipment. The new division has developed a transmission that combines range change, steering and braking.

After World War II, Allison Transmission turned its attention to civilian traffic. Allison designed, developed and manufactured the world's first automatic transmissions for heavy vehicles, including delivery trucks, city buses and locomotives.
