This paper presents industrial application of structural optimizations for automatic transmission of vehicles to achieve light weight and low radiated noise design. Optimization problems are formulated using types of size and shape optimization method and its purpose is to obtain optimal thickness distribution of the automatic transmission casing that minimizes mass and/or sound pressure radiated from automatic transmission. The optimization results show that the optimization method successfully found the optimization thickness distributions of automatic transmission casing that reduce mass and sound pressure.
