Automatic Transaxle

Even in the remarkable developments in the industry, the self-healing, self-improvements, self-mending and self-repairing are not invented, if self-modifications exist. Of course various trials are performed, the functions and features mentioned above like living thing have not yet created by human being.
For example, the automatic transaxle construction for automobile, many a trials are tested and actually introduced as new technologies, almost of them are aimed at human's comforts by adjusting some defected functions, not repairing fundametal problems.
It might be a bad way to express like this, such kind of functions looks an excuse for cheating the users?

The reason why I describe like this here putting an emphasis on the performance of automatic trans-axles, it is the decisive mechanical element of the taste and of the dignity of the automobile in combinations with it's engine performance.
