GMC, the Allison-branded automatic gearbox, produced by GM, was created to ensure increased operation characteristics and fuel efficiency, adaptability, ease of use, and durability.

GMC representatives claim that the transportation capacity of heavy goods with the help of a trailer is one of the most relevant features for Sierra customers and Allison’s solution became an excellent addition to Sierra’s design. The closer gear spacing of this gearbox enables the engine to work in an optimal range with different loads and road surface conditions.
