INDIANAPOLIS, March 10, 2026 – Allison Transmission Holdings, Inc. (NYSE: ALSN), a global leader in high-performance mobility and work solutions, announced a significant expansion in its long-standing partnership with Daimler Truck North America LLC (DTNA). The collaboration introduces two advanced fully automatic transmission offerings for DTNA's industry-leading Freightliner M2 106 Plus medium-duty truck.

The Allison 3414 Regional Haul Series™ (RHS) transmission paired with the Cummins X10 diesel engine in M2 106 Plus trucks will enter production in January 2027. Additionally, the Allison 9-Speed transmission paired with the Cummins B6.7 Octane engine in M2 106 Plus trucks will enter production in July 2026.

"When paired with the new Cummins X10 in an M2 106 Plus, the Allison 3414 RHS gives customers a lighter automatic option that helps the Freightliner M2 106 Plus meet the needs of medium duty tractor applications,” said Aaron Scates, vice president, Vocational and Medium Duty Market Development at Daimler Truck North America. “The Allison 9-Speed, paired with the Cummins B6.7 Octane, offers smooth, predictable shifting for customers choosing a gasoline configuration. Together, these transmissions broaden the range of powertrain options available to customers as they tailor the M2 106 Plus to their needs.”

The optimized powertrain pairing of the Allison 3414 RHS transmission with the Cummins X10 engine delivers proven performance and efficiency in medium duty tractor applications. The 3414 RHS is engineered to enhance vehicle handling and maneuverability and provides 25% faster acceleration when compared to competitive automated manual transmissions (AMTs). The fully automatic transmission has a torque capacity and gear ratio optimization that make it ideally suited for a diverse range of operating conditions in demanding duty cycles.

The Allison 9-Speed transmission paired with the Cummins Octane engine is designed to help fleets address the evolving efficiency requirements as well as offer a balance between torque delivery and fuel-saving capability for commercial truck applications.

"The expansion of our partnership with DTNA underscores a shared commitment to delivering powertrain solutions that best address our customers' needs," said Rohan Barua, Vice President, North America Sales, Global Channel and Aftermarket. "By integrating our 3414 RHS and 9-speed transmissions into the Freightliner M2 106 Plus platform, we are providing purpose-built technology designed to enhance productivity, efficiency and long-term value.”
