Fire + Emergency  

For emergency responders, failure is not an option. Fire trucks and ambulances are among the vehicles that must quickly arrive at scenes that frequently involve matters of life and death. Allison Transmission has spent decades designing and building fully automatic transmissions (“Allison Automatics”) that perform at their best in critical situations.

Allison understands the challenges facing emergency responders and the kind of performance the profession demands. Our transmissions are engineered to deliver superior acceleration for fast response times and better maneuverability on crowded city streets.

See how the numerous features of an Allison transmission deliver unrivaled reliability and a faster, safer response during an emergency situation.

Experience the Benefits

At Allison, we push our products to perform in ways that help emergency responders be more effective in their job and improve safety in the most challenging situations.

Allison Automatics offer features specifically designed to increase vehicle and driver performance at the scene of life-threatening emergencies whether they occur on the highway, in congested urban settings or off-road.

Faster response

In emergency situations, seconds can mean everything. That’s why vehicle performance and acceleration are absolutely critical. Thanks to our Continuous Power Technology ™, Allison Automatics provide seamless and uninterrupted engine power to the wheels, which results in up to 35% faster acceleration and quicker trip times. 

Improved safety

Allison has perfected its transmissions to facilitate outstanding driver safety. With an Allison fully automatic transmission, a driver simply places the vehicle in “Drive” and goes – allowing greater opportunity to focus on maneuvering through traffic, and managing emergency sirens and controls.

Since drivers don’t have to worry about shifting or pressing a clutch, they can spend more time handling and maneuvering their vehicle. With an Allison Automatic, vehicle operation is easy and stress free – so drivers have more time to take proper safety precautions.

At the scene of an emergency, an emergency responder is concentrating on both vehicle operation and assisting victims quickly. In these situations, you can rely on Allison’s integral retarder to ensure prompt and effective braking by reducing overall braking distance, which is especially important for a heavy vehicle traveling at high speeds.

Reliable, efficient operation

In situations where lives are in danger, emergency vehicles must be dependable. So we know that reliability is a key factor for emergency responders. An emergency vehicle sitting in the shop is one less vehicle available to save lives. That’s why Allison has worked for decades to build some of the most reliable and durable transmissions in the world. Allison Automatics will help keep your vehicle in service.

Routine oil and filter changes are the only regular maintenance required with an Allison Automatic. With Allison Prognostics, you can take the guesswork and hassle out of scheduling routine vehicle maintenance. This Smart Control feature, available with most Allison transmissions, allows you to quickly monitor oil life, filter life and transmission health. This saves 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. 

So in those mission-critical situations where you and your response team are needed to perform, you can rest assured your Allison-equipped emergency vehicle will be ready to go. 


Work Smarter

Allison Automatics have both intelligence and strength. We offer a number of Smart Controls – electronic control packages that provide superior performance and improved 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 control aggressive driving 
  • Enhancing braking with Allison’s ABS and EBS-compatible integral retarder

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 emergency response.

During tough summer months, the frequency of forest fires rises as temperatures do. In the area that stretches between Hatay, the Mediterranean, the Aegean coastal regions and Istanbul, flames can spread rapidly due to windy conditions. That means response time is crucial to protecting people, property and environmental resources. The General Directorate of Forestry has strengthened its fleet by adding BMC 625 model fire trucks, all benefitting from the power, speed and maneuverability of Allison fully automatic transmissions.
"We pay strict attention to international standards in fighting forest fires. While aiming to protect forests and forest resources against multiple hazards, fires are the riskiest by far. The test drives we undertook demonstrated the benefits of having Allison fully automatic transmissions in our fire trucks. Thanks to fast and easy maneuvers, our operations are even more successful. Moreover, our drivers are able to really focus on driving the vehicles during emergencies, rather than shifting."

–Salih Büyüktepe, General Directorate of Forestry (Istanbul, Turkey)
