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 reduce fuel consumption and increase productivity.

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 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 to further reduce costs, emissions and fuel consumption.

Improved maneuverability

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 and maneuvering the vehicle. With an Allison Automatic, there are no hesitations or jerks during gearshifts. The smooth acceleration allows vehicle operation to be easy and stress free while keeping your load protected. The ease of operating your vehicle and the increased safety will be evident – inching will be simple, and rollbacks a distant memory.

Reliable, efficient operation

Allison has worked for decades to build some of the most reliable transmissions in the world. They’re built to last and are known for performing reliably.

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 and automated manual transmissions (AMTs). And with an Allison Automatic, you’ll experience reduced brake wear as a result of 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 you time and money while providing maximum protection for the transmission. That means less downtime, lower life cycle costs and, best of all, greater in-service time for vehicles in your fleet.

Gear selector technology


Allison Automatics offer both intelligence and strength. We have a number of Smart Controls – electronic control features that can help increase efficiency, lower fuel consumption, reduce maintenance costs and improve overall 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 
  • Choosing the optimum shift points based on load and terrain 
  • Limiting vehicle acceleration rate, when desired by the fleet, to manage aggressive driving

Customer Profiles

We’ve told you why we think Allison Automatics are premium – now you can hear it straight from the customer.

Read this customer profile for more information on how Allison Automatics are playing key roles in the success of companies everywhere.

Steep hillsides, narrow dirt tracks, green valleys and ancient forests abound 150 km north of Auckland. In this rain-sodden forest, Douglas Logging employs a Scania G44 8x8 truck equipped with an Allison automatic transmission to get the job done every time, under some of the harshest logging conditions imaginable. On forestry tracks graded up to 40 percent, the Allison-equipped trucks have proven to be the safest, most efficient way to move felled timber from areas that normal logging trucks can’t reach.
"The Allison-equipped Scania goes places where no normal log truck would ever dare venture – enabling us to quickly move logs out of inaccessible areas to a skid site where we can load them onto a normal truck. It certainly calls for a good deal of trust in the Allison transmission; any snatching or jerks in the take-up when close to the edge could spell disaster. The Allison Automatic doesn’t jump or lurch and is very predictable.”

–Karl Thompson, Logging Contractor for Douglas Logging (Whangerei, New Zealand)
