Experience the Benefits

Allison Automatics are designed with features that improve passenger safety and comfort while delivering impressive fuel economy with proven reliability and durability.

Superior comfort and safety

When it comes to operating a fleet of coaches, there’s nothing more important than delivering your passengers and cargo to their destination. We concentrate on supplying transmissions that provide safety and comfort with seamless shifts. 

Without the distraction of manually changing gears, drivers are able to keep both hands on the wheel and focus on the traffic around them. While the smooth, seamless fully automatic shifting is safer, it’s also better for passenger comfort. With an Allison, there are no hesitations or jerks during gearshifts. The smooth acceleration and quiet operation ensure that passengers have a comfortable and relaxing ride.

Improved maneuverability and shorter route times

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 coach. This is especially important in heavy traffic situations and narrow roadways when maneuvering ease is critical.

The smooth, seamless power also results in higher coach efficiency. This means higher average speeds and shorter route times to meet schedules.

Lower costs, easier maintenance

Allison transmissions are known for their reliability. This means keeping your Allison-equipped coaches on the road and in service.

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.

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

 

Work Smarter

Allison Automatics have both intelligence and strength. We offer a number of Smart Controls – electronic control features that can help increase productivity, lower fuel consumption, reduce maintenance costs and improve overall coach 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 the success of coach fleets.

One of Singapore’s largest coach operators, Tong Tar Transport Service, has made a major shift in its bus operations with the introduction of the first buses equipped with Allison fully automatic transmissions in the company’s 44-year history. Recent advances in automatic transmission technology and associated electronics convinced Tong Tar to try Allison-equipped buses, which were found to be equal to manual buses in fuel efficiency and gear change control.
"The reliability of the Allison-equipped coaches has been excellent, and while we haven’t done any definitive comparisons in fuel consumption, they are certainly not using any more fuel than our manuals. We will definitely be looking to move our entire fleet to automatic transmissions, as a result of our experience with these new Allison-equipped buses."

–Philip Peh, direttore generale della Tong Tar Transport Service (Singapore)
