Transmission maker Allison  has announced two major OE contract wins with its 1000 Series and 2000 Series being announced as the  exclusive auto transmission fitment  for International’s new CV Series vocational trucks while GMC announced an Allison branded 10 speed automatic will be used in its Sierra pick up

In International the Allison 6-speed automatic is paired with the International 6.6L turbocharged diesel engine rated at up to 10.3 tonnes GVRW and capable of 16 tonnes GCWR.

Allison says the Inter fitted with its transmission features a Power Take-Off (PTO) option, close-ratios with double overdrive, to maximize fuel economy and full integration with the International 6.6L diesel V8 among other things.

Meantime, the availability of a 10-speed, fully automatic transmission in the new Sierra heavy-duty pick up is seen as as slap in the fact to Ford which is having trouble with its 10 speed auto in its HD F series models.

“Trailering is the most important consideration for Sierra Heavy Duty customers and the new features and technologies, including the Allison fully automatic transmission make it easier than ever to hitch a trailer and tow it confidently,” said Jaclyn McQuaid, GMC Vehicle Chief Engineer, Heavy Duty Trucks.

“The all-new 10-speed transmission with closer gear spacing allows the engine to operate in an optimal range at all times with varying load and terrain conditions.”

The Allison branded automatic transmission is manufactured by General Motors, but is branded Allison  to make it more attractive in the market.

“We are pleased that General Motors continues to expand the range of Allison products available for their customers with the Sierra,” said John Coll, senior vice president of global marketing, sales & service, Allison Transmission. “Allison Transmission and GM have a long history of collaboration and innovation.”
