Allison Transmission announces its first nine-speed model.
“With this new transmission, Allison continues to demonstrate its commitment to help achieve standards regarding fuel efficiency and greenhouse gas (GHG) emissions,” said Randy Kirk, senior vice president of product engineering and product teams with Allison Transmission. “This release coincides with the timing of the Environmental Protection Agency (EPA) Phase 2 GHG and Fuel Efficiency Standards.”
With its deep first gear ratio, the Allison nine-speed transmission provides significant fuel savings as the highly-efficient gear train allows the torque converter to lock up early in first gear. Additionally, the nine-speed includes an integral engine stop-start system that provides immediate transmission engagement and vehicle hold while the engine is restarted.
The Allison nine-speed model leverages the proven durability of the Allison 2000 Series six-speed commercial transmissions, which have accumulated more than 100 billion miles globally. It’s been designed to utilize the same OEM interfaces as its six-speed predecessor, providing ease of integration into vehicles currently released with the Allison 2000 Series.
Drivers will experience even better comfort due to smaller steps, allowing for a smoother start. They’ll also enjoy improved acceleration, which can lead to more productivity.
