Allison Transmission is the world leader in commercial duty automatic transmissions and our Torqmatic™ series of fully automatic powershifting transmissions is specially designed for the unique demands of city and surburban buses. The 2000 Series™ transmission is the ideal solution for smaller buses providing optimum performance and fuel economy.

Allison fully automatic powershifting transmissions combine torque converter operation with “closed loop” adaptive controls to provide the smoothest possible ride. Continuous electronic monitoring and adjustment enable the electronic control unit to “learn” how the vehicle is driven, ensuring perfect shifts that self-adjust to changes in load, terrain and traffic conditions.

Allison transmissions maintain constant power delivery to the wheels during gear changes, so acceleration is brisk and stead, even on steep grades. So your drivers can keep to their route times and your passengers are happy. Drivers enjoy easy, stress free operation and can give more attention to their passengers.

The electronically controlled output retarder in an Allison transmission allows smooth progressive stopping and the seamless transition between the retarder and service brakes ensures greater control at low speeds. Even on heavily congested city routes with constant stopping and starting, the exceptionally smooth shifts of an Allison transmission can go completely unnoticed by the passengers. They can just sit back and enjoy the trip.
