Allison automatics have been moving earth, in mines, construction sites, quarries, gravel pits for more than fifty years. They've proven to be durable and reliable in the most arduous duty cycles.
The technologically advanced electronic controls can be programmed for specific situations and offer self diagnostic ability for easier maintenance, programmable settings to customise the transmission to specific operating requirements, and a secondary shift that permits even more precise control of the job at hand.
