COURSE CONTENT

Student Learning Outcomes:
At the conclusion of this course, the student should be able to:

1. Demonstrate shop safety regarding working procedures and hazardous materials and waste handling.

2. Research and identify correct procedures and specifications for maintenance and repair of manual transmission and drive train systems.

3. Perform diagnosis, service, and maintenance procedures in a timely manner to industry standards.

 

Objectives:

At the conclusion of this course, the student should be able to:

1. Diagnose fluid usage, level, leakage, and condition concerns, drain and fill manual transmission/transaxle and final drive unit.

2. Diagnose clutch noise, binding, slippage, pulsation, and chatter, and determine necessary action.

3. Inspect, clutch pedal linkage, cables, automatic adjuster mechanisms, brackets, bushings, pivots, and springs and perform necessary action.

4. Inspect and replace hydraulic clutch slave and master cylinders, lines, hoses, and release bearing, lever and pivot; and perform necessary action.

5. Inspect and replace pilot bearing or bushing, release bearing, clutch pressure plate assembly and clutch disc.

6. Inspect flywheel and ring gear for wear and cracks, measure runout; and determine necessary action.

7. Diagnose noise, hard shifting, jumping out of gear, and fluid leakage concerns and determine necessary action.

8. Disassemble, clean, inspect and reassemble transmission/transaxle components.

9. Measure endplay or preload (shim or spacer selection procedure) on transmission/transaxle shafts and perform necessary action.

10. Diagnose constant velocity (CV), and universal joint noise and vibration concerns, and determine necessary action.

11. Inspect, service, and replace shafts, yokes, boots, and CV joints.

12. Diagnose final drive noise and vibration concerns and determine necessary action.

13. Inspect and replace companion flange, pinion seal, and measure companion flange runout.

14. Inspect ring gear, measure runout, and determine necessary action.

15. Remove, inspect, reinstall, and adjust drive pinion, seals, ring gear, spacers, sleeves, and bearings.

16. Measure and adjust drive pinion depth, and pinion bearing preload.

17. Check ring and pinion tooth contact patterns, gear backlash, and perform necessary action.

18. Inspect and flush differential housing, and refill with correct lubricant.

19. Inspect and replace drive axle shaft seals, bearings, and retainers.

20. Remove and replace drive axle shafts.

21. Disassemble, inspect, and reassemble transfer case and components.
