The Allison Bus Series of transmissions are designed for medium duty and heavy duty buses. Each type is available in 5 or 6 speeds with a retarder as an option. There are six models in the Bus Series. The main differences between them are listed below.

In 2015, Allison introduced a new model in the Bus Series. Part of the xFE (extra fuel economy) line, the B3400 xFE incorporates optimized gear ratios and features the FuelSense® Max electronic control package. New gear ratios also allow the torque converter to lock up at lower speeds. The xFE transmissions boast an up to seven percent improvement in fuel economy over baseline models.[1]
