Course Description: This course provides theory and principles of operation in automatic transmissions/transaxles, to include diagnostic, testing and repair of each system.

Upon successful completion of this course, the student should be able to:

1. Perform tests on automatic transmissions and transaxles using pressure gauges and scan tools to identify external or internal transmission/transaxle problems.
2. Remove and replace both front and rear wheel drive automatic transmissions/transaxles.
3. Tear down and reassemble transmissions using industry specific publications and determine a "good" part from a "bad" part prior to reassembly.
4. Identify internal automatic transmission components using industry terminology and demonstrate an understanding of powerflow through the various planetary components.
5. Correctly identify transmission types and perform routine service procedures including fluid exchange and external adjustments.
