Overview:
A global power train manufacturer sought a turn-key transmission final test equipment solution that could be implemented in several manufacturing sites around the world. In addition to providing the best technical solution and price, the successful supplier had to be able to support this global program at several sites in both the eastern and western hemispheres. Assembly & Test Worldwide (ATW) successfully met this challenge by designing and building the most robust, dependable, and flexible transmission final test systems possible. These final test systems are being fully supported by ATW facilities in the China and North America. Additional support could also be provided by ATW facilities in India, Europe, and South America.
