Richardson William J. Wegeng Allison Transmission Div. GMC ABSTRACT Allison Transmission has developed a family of two new automatic transmission products, the 1000 Series and the 2000 Series, for the light and medium duty commercial markets. This technical paper will introduce these products by reviewing the early development efforts which helped define the transmission attributes that they should bring to market. This included the analysis of Allison's product portfolio and industry rating requirement trends, and the extensive market research which identified the key product attributes and led to the concept selection. There is also a review of the 1000 Series and 2000 Series product features as well as a discussion on the development of their respective vocational ratings. Future papers will provide greater detail on the various technical aspects of this new product family's design. INTRODUCTION Allison Transmission began as the Allison Engineering Company, an engineering and manufacturing company, in 1915. Wholly owned by James Allison, the Allison Engineering Company focused on design, development, and manufacturing of automotive racing engines and aircraft engines. Purchased by Ge
