ASEP 125 - GM ASEP Driveline Mechanical Theory and Repair
PREREQUISITES/COREQUISITE: ASEP 100 Introduction to the GM ASEP Program
CREDIT HOURS MIN: 3
LECTURE HOURS MIN: 2
LAB HOURS MIN: 2
TOTAL CONTACT HOURS MIN: 64
In the first course of a two-part sequence, students begin studying the mechanical theory, diagnosis, service, and repair of modern GM automatic and manual drivelines, including longitudinally and transversely mounted transmissions. Emphasis is placed on the proper use of precision measuring tools and GM-specific tools and equipment to diagnose, service, and repair the mechanical, hydraulic, and electrical systems of transmissions found in GM passenger vehicles and light-duty trucks. Students also continue required GM Center of Learning (service technician online training) modules and prepare for the nationally recognized ASE (Automotive Service Excellence) certification exams.
MAJOR COURSE LEARNING OBJECTIVES:
- Demonstrate safe shop practices and work habits while working with driveline equipment and lifts.
- Demonstrate usage of tools for driveline diagnosis and repair.
- Describe basic power flow of a GM vehicle driveline.
- Identify GM fluid properties utilized in vehicle equipment.
- Repair GM late model transmission/driveline components
- Diagnose NVH and other Driveline issues on GM vehicles
- Locate specifications for drivelines from repair databases.
COURSE CONTENT: Topical areas of study include -
- Powertrain tools and equipment.
- Transmission diagnosis
- Manual and automatic transmissions systems
- Transmission fluid checks
- NVH diagnosis
- Drive shaft service
- Drive axle service
- C/V Joint operation Wheel bearings
