When it comes to construction applications, Allison fully automatic transmissions (“Allison Automatics”) fit operating requirements better than other transmissions because they’ve been engineered specifically for the way you work.

Our longstanding worldwide presence in the construction dump/tipper sector, as well as our prominent position in concrete mixers, demonstrates that Allison understands the construction industry. There are few hills too steep or terrain too tough for an Allison Automatic.

Robustness and maximum vehicle uptime are vital in construction and off-road businesses. Allison Automatics excel in these difficult conditions. Designed and built for high performance and low maintenance, Allison automatic transmissions have been shown to achieve faster work cycles and extended service intervals.

See how the numerous features of Allison Automatics help you get the most benefit and value from your transmission. You’ll understand why Allison has been trusted by the construction industry for decades to move gravel, earth and other materials while performing in the toughest conditions.

Experience the Benefits

Allison’s commitment to understanding and satisfying your goals is what drives us to constantly analyze, refine and improve our transmissions. We aim to push performance in ways that help you get work done smarter and more effectively.

With Allison Automatics, we offer features that maximize productivity, increase construction site safety and deliver renowned durability.

Greater productivity

Whether you’re driving on a smooth surface, on a gravel road, up or down hills or in the worst terrain imaginable, an Allison Automatic is a proven and effective solution.

Our transmissions are designed to accelerate faster, which means more earth moved or loads hauled per day. A better performing vehicle equals a higher performing driver – and that means an improved bottom line.

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 and 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 a much slower launch and difficultly maintaining momentum when shifting.  The ease of operating your vehicle and the increased safety with an Allison Automatic will be evident – inching will be simple, and the rollback experienced with a manual clutch will be a distant memory.

Lower costs, easier maintenance

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

Routine oil and filter changes are the only regular maintenance required with an Allison Automatic. 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 you time and money while providing maximum protection for the transmission.

And if ever needed, our global network of authorized service locations will provide the Allison authorized service you expect.

Improved safety

Allison has been perfecting our transmissions for decades to facilitate outstanding driver safety.

From combating vehicle rollback – a major concern with manual transmissions – to providing superior vehicle control and maneuverability, Allison Automatics help reduce accidents and improve driver awareness, comfort and safety.

Better fuel efficiency

With an Allison Automatic, you can achieve an optimum level of fuel economy and performance. Allison Automatics are designed to carry more tonnage per gallon/liter of fuel and give you a choice of operating modes to best suit your driving conditions.

Our transmissions offer load-based shift schedules to automatically enhance fuel savings or add more power when needed. In ‘economy mode,’ the transmission shifts at lower engine speeds to provide fuel savings, and upshifts at higher speeds for greater acceleration when required for the vehicle load and road conditions.


Work Smarter

Allison Automatics have both intelligence and strength. We offer a number of Smart Controls – electronic control packages that can help increase productivity, lower fuel consumption, reduce maintenance costs and improve safety. Features include:

  • Adapting to conserve fuel by reducing the 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 Power Take-Off (PTO) is enabled
  • Choosing the optimum shift points based on load and terrain
  • Limiting vehicle acceleration rate, when desired by the fleet, to control aggressive driving
