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 designed specifically to increase productivity while minimizing fuel consumption throughout your work cycle.

Greater productivity

Our transmissions drive greater productivity. Allison Automatics provide seamless and uninterrupted engine power to the wheels thanks to our Continuous Power Technology™, which results in precise maneuvering, smooth towing and easy operation in vehicles that perform a high number of stops and starts. Allison’s Smart Controls can manage the vehicle’s maximum average speed to optimize the cycle and minimize fuel consumption.

Allison believes durability is a key factor in productivity. The fact is, a vehicle sitting in the shop is costing you money – repairs are expensive and productivity is lost. That’s why Allison has worked for decades to build some of the most reliable transmissions in the world. They’re built to last and they don’t experience the same wear and tear as manual or automated manual transmissions (AMTs) with a starting clutch. Allison Automatics will help keep your vehicle in service.

Better fuel efficiency

With an Allison Automatic, you can achieve an optimum level of fuel economy and performance. Our transmissions select the optimum shift points based on load and terrain 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 only when required by the vehicle load and road conditions.

Choosing the Allison Automatic that best fits your expected duty cycle means you may be able to downsize your engine. This further reduces costs, emissions and fuel consumption. When paired with alternative fuels, Allison Automatics help lower emissions, reduce noise and improve vehicle performance. This makes our transmissions the clear choice for companies who are environmentally conscious.

Reliable, efficient operation

Allison’s Continuous Power Technology ™ allows our fully automatic transmissions to simply and smoothly deliver uninterrupted engine power to the wheels, letting the driver focus on handling the vehicle. It results in a smooth drive, effortless shifting, precise traction control and maneuverability – even in situations where tight turning and exact steering is required.

Allison transmissions are known for performing reliably, in many cases throughout the expected life of the vehicle, and will help keep your vehicle in service.

Lower cost, 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. And with an Allison Automatic, you can experience reduced brake wear due to the integral retarder.

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 packages that can help increase efficiency, minimize fuel consumption, 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
  • Choosing the optimum shift points based on load and terrain
  • Limiting vehicle acceleration rate, when desired by the fleet, to manage aggressive driving
