Experience the Benefits

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

Superior comfort and safety

When it comes to operating a fleet of city buses, there’s nothing more important than delivering your passengers to their destination, each and every day. We’re focused on supplying seamless-shifting transmissions that provide safety and comfort.

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 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 bus. This is especially important in heavy traffic situations and narrow roadways when maneuvering ease is critical. The smooth, seamless power also results in greater bus efficiency. This means shorter route times to meet stringent bus schedules.

 Lower costs, easier maintenance

Allison transmissions are known for performing reliably in tough duty cycles. This means keeping your Allison-equipped buses on the road and in service.

To take the guesswork and hassle out of scheduling routine vehicle maintenance, our Prognostics feature 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 needed, our global network of service locations will provide the Allison authorized service you expect.

Better fuel efficiency

With an Allison Automatic, you can achieve an optimum level of fuel economy. Our transmissions offer several fuel-saving features that allow the transmission to shift at optimum points based on terrain, load and operating conditions. To reduce the impact of aggressive driving practices, Allison automatics can control the rate of vehicle acceleration and further conserve fuel.  And when the bus is stopped, the transmission automatically lowers fuel consumption by reducing the load on the engine.

 

Greater life cycle value

With transmissions, it comes down to overall value. When you factor in maintenance, operating costs and increased productivity, Allison Automatic-equipped buses create an advantage for our customers. Overall, our transmissions demonstrate a greater value across the life cycle of the bus.

Work Smarter

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

The Pinellas Suncoast Transit Authority (PSTA) provides public transportation services to around 40,000 riders a day in Pinellas County, Florida, which includes the St. Petersburg, Clearwater and nearby beaches on the Gulf of Mexico.
"We're seeing about 6.2 miles per gallon versus our regular transit vehicles at just about 3.65. It's a significant fuel savings, especially when you base that on somewhere around 3,000,000 miles annually."
Billy Johnson, PSTA Maintenance Superintendent
