Course Description: This course provides theory and principles of operation in manual transmissions and transaxles, front and rear axles, drive lines and transfer cases. Shop practice includes diagnostics, testing, and repairing of each system.
Objectives
Upon successful completion of this course, the student should be able to:
- Identify the different types of manual transmissions and transaxles found in today's cars and light trucks.
- Tear down, inspect, and reassemble a manual transmission/transaxle, a transfer case, and a differential assembly.
- Diagnose and repair manual transmission/transaxle, transfer case, and differential concerns.
- Identify the different types of front and rear differential designs found in today's cars and trucks.
- Identify the different types of transfer cases and electronic differentials found in today's cars and trucks.
- Describe power-flow through each gear of a manual transmission, transfer cases, and a differential assembly.
