Allison used the Atlanta Truck show to announce plans for its new nine-speed fully automatic transmission due in 2020.

The new nine-speed transmission has a deep first gear ratio, includes an integral engine stop-start system\ and is scheduled to be released to coincide with the USA Environmental Protection Agency’s Phase 2 GHG and Fuel Efficiency Standards.

“This nine-speed product launch represents the first in a number of new products which will demonstrate Allison’s ongoing commitment to addressing the global challenge of improved fuel efficiency and reduced greenhouse gases,” said Allison’s senior vice-president of product engineering, Randy Kirk.

Kirk added the new nine-speed will reach up to seven per cent greater fuel efficiency than the current base six-speed model.

“The new nine-speed will set a new benchmark for fuel savings,” he said. “Customers can also expect up to 10 per cent greater fuel economy or more when compared to a competing transmission.”

The new transmission marks the first of its kind for the medium-duty market, specifically distribution trucks, rental and lease trucks, and buses, Kirk said.

Kirk said that drivers can also look forward to better comfort due to smaller steps, a smoother start, and improved acceleration with the new transmission and that the new gearbox will succeed the company’s six-speed transmission when it is released.

Allison claims the new nine-speed leverages track record of its current 2000 Series 6-speed, which they say, has accumulated more than 100 billion miles in-service globally and to keep things simple for OEMs it has been designed to utilise the same interfaces as the six-speed predecessor
