Allison Transmission Holdings, Inc.
A maker of fully automatic transmissions for medium- and heavy-duty commercial vehicles and U.S. defense tactical trucks, Allison builds the gearboxes that power buses, delivery fleets, and military vehicles around the world. It traces its roots to 1915, when Indianapolis racing enthusiast James Allison founded the Speedway Team Company to maintain his race cars at the Indianapolis 500 he helped create; after his death, General Motors bought the firm and it later became the independent Allison Transmission. Its transmissions are known for smooth, fuel-efficient shifting in stop-and-go work, and it is also developing electric propulsion systems under the eGen Flex and eGen Power names.
