Transit + City Bus

For more than 100 years, Allison Transmission has been leading the charge in innovative propulsion solutions. No matter your fleet—conventional diesel, CNG, electric hybrid or fully electric—you can trust Allison to drive you into the future.


We know every route is important, so each product that comes off our line delivers the industry’s most reliable customer support network. No matter your needs, we’ll be there every mile.


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.


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.


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.


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 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. 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.


FuelSense® 2.0 provides impressive fuel savings for the demanding duty-cycles of construction applications. This innovative technology solution uses a unique set of software and electronic controls to deliver quantifiable fuel savings of up to 6%, all while maintaining the traditional Allison advantages of quality, reliability, durability and productivity.


With xFE, Allison has taken fuel economy to the next level. xFE is another in a string of innovative, fuel-saving ideas from Allison, a leader in bus transmission technology. New gear ratios allow the torque converter to lock up at lower speeds, improving fuel economy by up to seven percent in xFE-equipped vehicles. This seven percent improvement in fuel economy is in addition to the already greater efficiency created by Allison’s FuelSense®, a unique package of software and electronic controls that supports an advanced array of features. The combination of these packages provides a substantial fuel economy advantage.


Allison Automatics get the most out of medium- and heavy-duty vehicles equipped with natural gas engines—both compressed (CNG) and liquefied natural gas (LNG). This allows these vehicles to maximize performance while using the cleaner and quieter natural gas engine. Our torque converter’s superior control at low speed and multiplication of engine torque give natural gas engines superior launch, while our electronic controls and gearbox designs allow for full-power shifting.
