Grove vehicle equipped with an Allison transmission.


Allison fully automatic transmissions (“Allison Automatics”) are designed to meet the demands of vehicles that require on- and off-road performance as well as precise control. Specialty Series transmissions are configured for worldwide use in crane and military wheeled vehicles. Allison Transmission provides the ability to easily operate in any environment, from city streets and highways to muddy slopes and combat environments.

Our transmissions are engineered and designed for reliability and durability – which means you don’t have to worry about how Allison Automatics will perform in any terrain or setting.

See how the numerous features of Allison Automatics help you get the most benefit and value from your vehicle.

Experience the Benefits

Allison designs and builds transmissions with the goal of helping you, the customer, efficiently run your operation. We aim to push performance in ways that help you get work done smarter and more effectively.

Allison Automatics offer features that increase performance and improve maneuverability while reducing maintenance costs and downtime.

Maximum performance and improved maneuverability

Allison’s Continuous Power Technology™ allows our fully automatic transmissions to simply and smoothly deliver uninterrupted engine power to the wheels. This means superior acceleration, a smooth drive, effortless shifting, precise traction control and improved maneuverability – even in harsh or rugged conditions. It also helps the driver control the vehicle at low speeds. 

Compare this performance to a manual or automated manual transmission (AMT) – which can have much slower launch and difficulty maintaining momentum when shifting. With an Allison Automatic, the ease of operating your vehicle and the increased safety will be evident – inching will be simple, and the rollback experienced with a manual clutch will be a distant memory.

Reliable, efficient operation

Allison transmissions are known for performing reliably and will help keep your vehicle in service.

Whether you’re driving on a smooth surface, a gravel road or up and down hills, an Allison Automatic is the most efficient and effective solution on the market. Equipped with maximum Power Take-Off (PTO) and built for easy integration with the crane and other special equipment, Allison Automatics are designed to get more work done while making the driver’s job easier.

Lower costs, easier maintenance

Allison makes transmission care easy and less costly. Since Allison Automatics don’t have a starting clutch, you won’t have routine clutch damage or need replacements – a major cost and downtime concern with manual transmissions and AMTs. 

Routine oil and filter changes are the only regular maintenance required with an Allison Automatic. And if ever needed, our global network of authorized service locations will provide you with the Allison service you expect. 

With Allison’s Prognostics feature, you can quickly monitor oil life, filter life and transmission health to take the guesswork and hassle out of scheduling routine vehicle maintenance. This saves time and money while providing maximum protection for the transmission.

Gear selector technology

Work Smarter

Allison Automatics offer both intelligence and strength. We have a number of Smart Controls – electronic control features that can help increase performance, improve maneuverability, reduce maintenance costs and improve overall safety. Features include:

  • Adapting to conserve fuel by reducing load on the engine when a vehicle is stopped
  • Automatically selecting neutral when the parking brake is applied
  • Avoiding unwanted shifts out of neutral when the PTO is enabled
  • Choosing the optimum shift points based on load and terrain

When Manitowoc, a leading manufacturer of lifting equipment for the construction market, introduced a new six-axle, all-terrain crane, they chose to equip it with an Allison Automatic.
"The Allison 4500 SP is a strong, reliable and cost effective drivetrain solution. Its capabilities are proven even in the most arduous conditions and the electronic controls allow it to adapt to its surroundings and provide self-diagnostics for easier maintenance. An integral retarder offers enhanced braking on hills and greater safety for the operator when moving a heavy vehicle."
