POWERMATIC A New Automatic for Chevrolet Transmission Heavy-Duty Trucks

THIS paper describes the development of a truck automatic transmission, from a statement of broad objectives through the growing pains, to road testing of the final product. Emphasis is placed upon original thinking that led to the decision to undertake such a project, compromises that suggested themselves throughout the various stages, and features tried and found wanting as well as those retained.

The finished product is described full though not in detail, stress being placed upon interesting and novel design features.
