Allison Transmission manufactures fully automatic transmissions and propulsion systems for commercial vehicles and other demanding equipment applications. Its transmissions are used in delivery trucks, vocational vehicles, buses, and specialized equipment.
Truck Equipment Atlas connects Allison’s company background with individual transmission profiles, related equipment, and educational guides. These resources help drivers, owner-operators, fleet managers, technicians, and equipment buyers understand Allison products and their role within a complete vehicle powertrain.
History and Background
Allison traces its origins to 1915, when James A. Allison founded the Speedway Team Company in Indianapolis to support his racing activities. The business expanded into engineering and manufacturing, later becoming the Allison Engineering Company.
The company became part of General Motors and developed equipment for aviation, military, and transportation applications. Allison entered the commercial transmission field in 1947, supplying transmissions for buses before expanding its automatic transmission offerings for commercial trucks.
Allison became independent from General Motors in 2007. Today, its portfolio includes conventional automatic transmissions, electric hybrid propulsion systems, and fully electric propulsion solutions. Indianapolis remains the location of its global headquarters and a major engineering and manufacturing campus.

Technology and Product Development
Allison’s conventional automatic transmissions use torque-converter technology and automatic shifting to support vehicle operation across changing loads and speeds. Their suitability depends on the exact transmission model and the vehicle’s intended work.
Allison’s technology portfolio also includes electronic controls, fuel-management features, connected services, and electrified propulsion equipment. Available functions vary by product generation and vehicle configuration.
When comparing transmissions, review engine compatibility, operating weight, gearing, power take-off requirements, and maintenance documentation. Identifying the installed model is essential when selecting parts, fluids, or service procedures.
