INDIANAPOLIS, May 20, 2025 – Allison Transmission, a world leader in commercial vehicle transmissions, is excited to announce that its 3000 Series™ automatic transmission is now available in the CNG-powered Mack Granite® for waste management customers. This latest release follows the successful launch of the Allison 4500 Rugged Duty Series™ transmission with the Mack Granite CNG in 2023.

“This expanded powertrain option gives our customers more flexibility to optimize their trucks specifically for lighter duty waste applications,” said Jonathan Randall, president, Mack Trucks North America. “By offering the Allison 3000 paired with the L9N, we're delivering a solution that reduces acquisition costs while maintaining the reliability and performance Mack customers expect, particularly for light-duty roll-off applications where a higher GVWR isn't necessary.”

Allison transmissions pair seamlessly with different fuel types, including diesel, compressed natural gas (CNG) and other alternative fuels. Allison-equipped natural gas vehicles maximize performance while reducing emissions and engine noise levels, leading to a better experience for drivers, customers and the general public.

"Pairing Allison transmissions with natural gas engines leverages our torque converter to ensure peak performance and fuel efficiency. Unlike manuals and AMTs, our automatics maintain seamless, full-power shifts, enabling vehicles to travel farther in less time. This allows refuse fleets to achieve sustainability goals without sacrificing productivity," said Rohan Barua, Vice President, North America Sales, Global Channel and Aftermarket, Allison Transmission. "The CNG-powered Mack Granite will optimize fleet productivity, improve fuel economy and reduce emissions. We are proud to partner with Mack on this initiative."

The 3000 Series™ is designed to make medium and heavy-duty vehicles more fuel efficient and easier to operate. They are engineered to meet the demands of various applications including distribution, refuse, utility services, fire and emergency, transit buses and more. 3000 Series™ transmissions can accommodate engines with power ratings ranging from 210 to 450 horsepower (157-336 kW) and torque capacities up to 1,250 lb-ft (1,695 N·m).
