Automatic Transmissions
“Proven Reliability in Critical Situations”
Allison fully automatic transmissions are designed to perform under the most demanding conditions. The Continuous Power Technology in every Allison transmission delivers more power to the wheels than other technologies, enabling faster acceleration compared to manual or automated manual transmissions (AMT). This results in higher daily transport capacity.
More loads per day translate into greater productivity—and ultimately, better results. That’s productivity. Allison’s reliability ensures your fleet spends more time on the road and less in the garage.
No matter your task, Allison helps you do it better.
Allison is ideal for off-highway vehicles. The Off-Road Series (ORS) is a new generation of smaller, lighter, and more robust transmissions designed for off-road applications between 44,500 kg and 81,000 kg.
Ideal applications for Allison transmissions include:
- Construction and civil works
- Self-propelled cranes
- Dump trucks
- Military vehicles
- Oil fields
