Allison 1000 Series transmission brings superior performance of electronic controls from 6 to 11.8 tonne vehicle GVW. The engine and transmission communicate by a powerful microprocessor providing precise, perfectly timed shifts whatever the road or load conditions. Standard features include lock-up operation in second to fifth range and helical gearing for reduced transmission noise.
Allison 2000 Series transmission is designed for commercial trucks and smaller buses with gross weights up to 15,000 kilos (33,000lbs). The transmission increases torque capacity for higher powered vehicles within a lighter weight package. Adaptive technology ensures that optimum performance is maintained at all times. It also enables the transmission to compensate for variations in driving conditions, such as loads, drivers and traffic patterns. Standard features include the availability of close and wide ratio gearing and a turbine-driven PTO provision with optional neutral lock-up.
