Allison Transmission Truck Parts
Allison Transmission is the world's largest manufacturer of fully automatic transmissions for medium- and heavy-duty commercial vehicles, with a track record stretching back over a century. Their transmissions are engineered for demanding vocational and on-highway applications, offering smooth shifting, reduced driver fatigue, and lower maintenance compared to manual and automated manual alternatives. Allison automatics use a torque converter rather than a dry clutch, which provides better low-speed maneuverability and eliminates clutch replacement costs.
