Allison Transmission has introduced its first nine-speed automatic gearbox at the IAA Commercial Vehicle Show 2018 in Hannover. The fully automatic transmission is suited for medium- and heavy-duty vehicles and is targeted for release in 2020. Already coach manufacturer Van Hool is providing their EX and TX range with Allison automatic gearboxes.

With its deep first gear ratio and industry-leading ratio coverage, 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 utilize the same OEM interfaces as its six-speed predecessor, providing ease of integration into vehicles currently released with the Allison 2000 Series. The new gearbox has smaller steps in gear shifting allowing for a smoother start. Also the acceleration is improved, Allison claims. Belgium coach builder Van Hool provide their customers with the opportunity to have an EX or TX model with an Allison six speed T525R Torqmatic gearbox in combination with a DAF/Paccar MX 11 or 13 litre engine.
“With this new nine speed transmission, we continue to demonstrate our 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.”
