The automatic transmission is the difficulty in assembly of vehicle maintenance and repair is one of the largest, but also the most difficult to explore. People to the car is becoming more and more high, the requirements of all aspects of performance that will guide the car toward digital, intelligent direction. At present domestic maintenance technology is relatively backward, and to change the status quo, prompting the development of automobile technology, this paper takes a typical three kinds of passat type automatic transmission is analyzed, this paper first introduces the development history and classification of automatic transmission, and then discusses in detail the structure and working principle of three kinds of typical transmission, finally expounds the automatic gearbox fault diagnosis and elimination method. And summarize the basic principle and the structure characteristic of this kind of transmission.
