Allison automatics to be standard in Freightliner's natural gas trucks

The Cascadia 113 natural gas tractor will be powered by the Cummins Westport ISX12 G engine, paired exclusively with the Allison 4000-series transmission, Allison announced.

Allison 3000-series transmissions will be exclusive in Freightliner’s M2 112 and 114SD natural gas trucks powered by the Cummins Westport ISL G 8.9-litre engine.

“Allison transmissions are the ideal option for alternative fuel vehicles because of their torque converter technology that results in improved startability at the launch of the vehicle, full power shifts and better performance,” said Robert Carrick, vocational sales manager, natural gas, with Freightliner Trucks.

Allison says its fully-automatic transmissions are ideal for natural gas applications because there is no power interruption during gear changes, which is important given a natural gas engine’s longer torque response time.

“Natural gas technology is an exciting option in the commercial trucking market and we’re proud that Allison is a leader in this area. Customers anxious to experience the new Cascadia 113 Natural Gas tractor will be able to take advantage of all that natural gas engines have to offer while getting Allison’s renowned reliability, durability and performance,” said Jim Wanaselja, vice-president North American marketing, sales and service, for Allison Transmission.
