Daimler Truck North America Integrates Allison Transmission’s 3414 Regional Haul Series™ with Low-Emissions Natural Gas Engine into Freightliner Cascadia

Allison’s 3414 Regional Haul Series™ now available in Freightliner Cascadia Day Cab trucks equipped with Cummins ISX12N engine.

INDIANAPOLIS, February 7, 2023 – Allison Transmission is pleased to announce that the Allison 3414 Regional Haul Series™ (RHS) paired with the Cummins ISX12N engine is now available for order in Daimler Truck North America’s (DTNA) Class 8 Freightliner Cascadia Day Cab (116 in. BBC) model.

“After initially introducing the Allison 3414 RHS into Cascadia models when paired with the DD13 diesel engine in early 2022, we determined that our customers were eager for additional powertrain options,” said Steve Mignardi, Vice President of Market Development On-Highway Segment at DTNA. “The 3414 RHS, combined with Freightliner’s Class 8 platform and a natural gas engine from Cummins, provides customers with an industry-leading solution that maximizes payload and performance while reducing emissions and engine noise levels.”

The award-winning 3414 RHS fully automatic transmission is designed to increase vehicle handling and maneuverability in urban duty cycles and provide leading performance and efficiency, all while improving fuel economy by up to 8% over the Allison 3000 Highway Series™ transmission. The lightest transmission in the segment, the 3414 RHS also provides 25% faster acceleration when compared to competitive automated manual transmissions (AMTs), while also eliminating downtime associated with AMTs through the avoidance of clutch replacements. The fully automatic architecture translates into more deliveries, reduced route times and more productivity, especially in frequent start-stop duty-cycles.

“Allison is proud to partner with DTNA to expand the options available to customers looking to optimize the productivity of their fleets, increase fuel efficiency and raise driver retention rates,” said Rohan Barua, Vice President, North America Sales, Global Channel and Aftermarket at Allison Transmission. “Our torque converter’s superior control at low speed and multiplication of engine torque give natural gas engines superior launch, while our electronic controls and gearbox designs allow for full-power shifting. This enables customers to reduce emissions, improve driver comfort through ease of operation and maintain industry leading performance.”
