Allison Transmission Holdings, Inc. ALSN

Company Overview

Allison Transmission Holdings, Inc. is a U.S.-based manufacturer of fully automatic transmissions and electrified propulsion systems primarily serving commercial-duty vehicles. The company operates in the transportation and industrial machinery sectors, supplying propulsion solutions for medium- and heavy-duty trucks, buses, motorhomes, construction equipment, defense vehicles, and energy applications. Allison is best known for its automatic transmission systems used in vocational and commercial vehicle markets where durability, reliability, and performance under demanding operating conditions are critical. Revenue is primarily generated through sales of transmission systems, replacement parts, support equipment, service offerings, and emerging electrification technologies.

The company’s principal business lines include on-highway transmissions, off-highway propulsion systems, defense vehicle propulsion solutions, and electrified vehicle systems. Allison serves original equipment manufacturers (OEMs), distributors, fleet operators, and government customers across global commercial vehicle markets. A significant strategic advantage is its established installed base of transmissions, which supports recurring aftermarket parts and service revenue. Founded in 1915 as part of General Motors and later spun off through private equity ownership before becoming publicly traded in 2012, Allison evolved from a defense and industrial transmission manufacturer into a global commercial propulsion technology company with increasing focus on electrification and hybrid propulsion platforms.
