Allison Transmission Holdings Inc

Allison Transmission Holdings Inc. designs and manufactures propulsion solutions centered on fully automatic transmissions, electric hybrid propulsion, and fully electric propulsion systems for commercial and defense vehicles. Founded in 1915 and headquartered in Indianapolis, the company has built a large installed base that supports a meaningful aftermarket in service parts, fluids, remanufactured products, and support equipment. Its business is organized around on-highway, off-highway, defense, and aftermarket end markets, with sales reaching OEMs, body builders, distributors, dealers, and large end users. In 2026, the company expanded further into off-highway drivetrain and motion systems through the acquisition of the Acquired Off-Highway Business, broadening its exposure beyond traditional on-highway transmissions.
