Allison Transmission MD 9 Speed

Allison Transmission Plans To Offer Its Medium-Duty, Fully Automatic 9-Speed Transmission Globally.

ALLISON MD9 2000 SERIES TRANSMISSION

“Right now is an exciting time to be part of Allison and our industry as a whole,” said David S. Graziosi, president and CEO of Allison Transmission. “There is more rapid change in our industry and more Allison initiatives underway today than at any point during the last decade.”

With its deep first gear ratio and excellent ratio coverage, the Allison 9-speed transmission provides fuel savings as the highly efficient gear train allows the torque converter to lock up early in first gear. Additionally, the 9-speed includes an optional integral engine stop-start system that provides immediate transmission engagement and vehicle hold while the engine is restarted. Providing value for a variety of applications, the 9-speed transmission is ideal for distribution trucks, rental and lease trucks, and school buses.

“With the new 9-Speed transmission, Allison continues to demonstrate its commitment to help achieve standards regarding fuel efficiency and emissions,” said Randy Kirk, senior vice president of product engineering and program management with Allison Transmission. With its industry-leading ratio coverage and Allison fuel-saving technologies such as FuelSense® 2.0, xFE, and Dynactive Shifting, the Allison 9-Speed transmission provides significant fuel savings. Other exciting features include higher engine and GCW ratings, optimized skip shifting, lifetime filter, integral cooler, input retarder, and integrated engine stop-start system with vehicle hold. The 9-speed provides value for a variety of applications including distribution trucks, rental and lease trucks, school buses, specialty trucks, and defense vehicles.

“With this new transmission, Allison continues to demonstrate its commitment to help achieve standards regarding fuel efficiency and vehicle emissions,” Graziosi said.

The Allison 9-speed model leverages the durability of the Allison 2000 Series 6-speed transmissions, which have accumulated more than 100 billion miles globally. It was designed to utilize the same vehicle manufacturer’s interfaces as its 6-speed predecessor, providing ease of integration into vehicles currently released with the Allison 2000 Series.

The Allison 9-Speed model leverages the proven durability of the Allison 2000 Series™ six-speed commercial transmissions, which have accumulated well over 100 billion miles globally. It’s been designed to utilize the same vehicle and engine 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 range steps, allowing for a smoother start. They’ll also enjoy improved acceleration, which can lead to more productivity.
