Course Description

Introduces manual transmissions/transaxles, the study of power flow and diagnosis of manual transmission systems. Includes proper repair procedures, component identification and service procedures performed on school-owned vehicles and components. Audit available.

Addendum to Course Description

This course is designed for students with no previous industry experience. Students will develop the skills, knowledge and attitudes necessary to perform, repairs on import and domestic cars and light trucks. This course will prepare students for Advanced Automatic and Manual Drivetrain (AM132), where they will practice learned skills on customer vehicles to diagnose and repair manual transmission and transaxle with limited supervision. This is the skill level necessary for employment at an apprentice level.

The broader purpose of this course is to provide students, at the beginning of their first year in the automotive program, with authentic experience in basic industry skills and concepts, to ensure their success in later courses and on-the-job. These skills include tool use, fastener tightening, ASE (Automotive Service Excellence) style test taking, professionalism and responsible customer service.

Course material will be presented in a lecture/laboratory format and include videos, handouts and hands-on lab experience in the shop on donated vehicles. Students are required to read assigned materials, take notes and be responsible for the information in the textbooks and lab manuals and electronic service information located at each of the work areas throughout the automotive labs.

Intended Outcomes for the course

Upon completion of the course students should be able to:

  • Perform manual drive train inspection, maintenance, diagnosis and repairs.
  • Access and utilize repair information in a rapidly changing technology.
  • Develop and implement strategies and processes to solve manual drive train repair problems.
  • Perform manual drive train repairs to professional and ethical standards.
  • Communicate professionally with employers, customers and co-workers using industry standard language and following industry standard protocols.

Outcome Assessment Strategies

Students will be assessed on the following course work for Drivetrain Systems I:

•Performing a complete manual transmission/transaxle inspection and service.
•Remove and reinstall transmission/transaxles.
•Inspect transmission/transaxles and perform necessary action.
•Diagnose noise, hard shifting, jumping out of gear, and fluid leakage concerns; determine necessary action.
•Remove and replace transaxle final drive.
•Perform drive shaft and half shaft, universal and constant-velocity (CV) joint diagnosis and repair.
•Perform drive axle diagnosis and repair on a rear wheel-drive axle.
•Perform ring and pinion gears and differential case disassembly and assembly.
•Perform four-wheel drive/all-wheel drive component diagnosis and repair.

 Demonstrate professional skills and attitudes throughout AM-131 by:

•Maintaining good attendance.
•Following safe shop procedures.
•Demonstrating respect for other students and school property.
•Participating and completing all required activities.

 Demonstrate preparedness for ASE testing by taking all AM 131 ASE style written exams.
 

Course Content (Themes, Concepts, Issues and Skills)

Critical to the effective diagnosis and repair of any automotive system is an understanding of how and why certain components work. On today’s automobile, this is often more useful for the technician than the ability to perform a particular adjustment or replacement. A technician must also have the ability to determine which repairs are in their own and customer's best interest. To develop this background understanding of automotive manual transmission/transaxle systems, students will explore the following concepts:

Health and safety:

•Hazards of chemicals used in cleaning and lubrication of the manual transmission/transaxle assembly.
•The importance of shop cleanliness.

Professional business and personal conduct:

•Customer safety.
•Repeat repairs.
•Communication with customers.
•Customer satisfaction as business strategy.
•Teamwork in the work place.
•Cooperative problem solving.
•Work absence and attendance.

Physical laws:

•Energy transfer.
•Heat and friction.
•Hydraulic theory.

Specific system and component operation:

•Clutch assemblies, hydraulic, cable and rod-level mechanisms.
•Bell housing , clutch cover and clutch disc.
•Flywheel, starter ring gear, pilot bearing and input shaft.
•Transmission/transaxle assemblies, Forward gears and reverse.
•Transmission/transaxle shift linkages, bushings, bearings and gaskets and seals.
•Drive shafts, half shafts, universal joints and constant-velocity joints.
•Drive axles (front wheel drive), ring and pinion gears and differential case assembly.
•Limited slip differential, lubrication and theory.
•Four-wheel drive/all-wheel drive component theory.

Skills:

In Manual Drive Train and Axles, students will build an inventory of the following repair skills to prepare for a career as an apprentice technician.

•Drivetrain diagnosis.
•Clutch diagnosis and repair.
•Transmission/Transaxle diagnosis and repair.
•Drive shaft, drive axle, universal joint and constant velocity joint diagnosis and repair.
•Drive axle diagnosis and repair, ring and pinion gears and differential case assembly.
•Limited slip differential diagnosis and repair.
•Four wheel drive/all wheel drive component diagnosis and repair.

Related Instruction

Computation
Hours: 10

1. Perform manual drive train inspection, maintenance, diagnosis and repairs to industry standards.
 

Students measure transmission components using precision instruments, such as micrometers and dial indicators, and compare results with manufactures/industry specifications.

Students perform transmission/differential analysis/testing, using gear ratio analysis, case spread, endplay, etc…, and compare readings to manufacturers/industry specifications.

Assessment:  Feedback is immediate, direct and pass/no pass for classroom or lab assessed activities.  Homework and exams are “A-F” grades with direct feedback delivered within 1 week.

Communication
Hours: 5

1.  Develop and implement strategies and processes to solve manual drive train repair problems.
2. Communicate professionally with employers, customers and co-workers using industry standard language and following industry standard protocols.

Students verbally explain power flow of various manual transmissions in all gear ranges.  Students practice power flow at home and with peers in/out of class in preparation of assessment with instructor.

Assessment:  Feedback is immediate, direct and pass/no pass for classroom or lab assessed activities.  Homework and exams are “A-F” grades with direct feedback delivered within 1 week.

Human Relations
Hours: 15

1. Perform manual drivetrain repair to the highest professional and ethical standards.
 

Students build on previous course work in human relations to continue the practice of human relations introduced through class discussions and homework.
Students work in teams to complete assigned lab projects.  Team work is focused on working in a diverse cultural environment, being sensitive to Others needs and diffusing difficult situations in a calm and respectful manner. 
Students work with lab partners, staff members, and their instructor to bring customer/school cars in /out of the shop for class lab projects.
