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.

  • Automatically selecting neutral when the parking brake is applied
  • Choosing the optimum shift points based on load and terrain
