Abstract: As the most important and basic performance, The excellent dynamical and economical performance often depends upon reasonable matching of power and transmission. genetic arithmetic has been adopted to reasonably match the power and transmission of automobile , during which the optimization design idea is applied. The result data from the optimizing calculation shows that the genetic arithmetic is a effective method. this research improves the dynamical and economical properties, avoids the de
