This is a comprehensive lecture and laboratory class which focuses on the operation, diagnosis and repair of automatic transmissions and transaxles. In order to help the student understand how an automatic transmission accomplishes multiple gear ranges, power flow through the transmission will be stressed. The operation of electronic transmission controls will be discussed and diagnostic procedures will be taught and implemented. In-car transmission service and repairs will also be discussed and performed. The laboratory component of the course includes various activities that follow the guidelines of the National Technicians Education Foundation (NATEF). A library/internet research written project concerning some aspect of automatic transmission/transaxle operation will be assigned and is an integral component of this course.
