Allison Transmission

Allison's reputation for providing quality products began in 1915 in a small machine shop near the Indianapolis Motor Speedway. During World Wars I and II, the company produced U.S. Military trucks, tracked vehicles and airplane engines.

Allison's post-war efforts focused on power transmissions in medium and heavy-duty vehicles. Allison was the first to match a torque converter with a powershift transmission for the off-highway market.

In 1946, the company built the first V drive hydraulic transmission for transit buses. On-highway, the Allison Torqmatic blazed the trail for automatics in a variety of applications.

This tradition of innovative thinking has led to over 500 patents.
