COURSE CURRICULUM
COURSE TITLE: AUTO TRANSMISSION-MECHANISM DIAGNOSIS AND
TESTING
(COURSE CODE:3360202)

Diploma Programme in which this course is offered Semester in which offered

Automobile Engineering Sixth

1. RATIONALE
This course is designed to develop the deeper understanding in the students about the
troubles occurring in automobile transmission and chassis system and its probable
causes. They will be exposed to systematic method of working using standard trouble
shooting procedure rather than taking adhoc remedial measures. This will make the
learning more interesting and would develop desired skills for proper maintenance of
different component of auto transmission mechanisms.

2. COMPETENCY

The course content should be taught and implemented with the aim to develop required
skills in the students so they can acquire the following competency:
 Remedy automobile transmission systems based on diagnosis and testing
using suitable instruments and tools.

3. COURSE OUTCOMES

The theory should be taught and practical should be carried out in such a manner that
students are able to acquire different learning outcomes in cognitive, psychomotor and
affective domain so that they can demonstrate the following course outcomes.

i. Identify probable faults/troubles and their causes in automobile transmission systems.

ii. Use suitable instruments, tools and service manuals for diagnosis and testing of
automobile transmission systems
iii. Remove automobile units by using proper tools and procedures: gear box, brakes,
suspension, final drive, etc.
iv. Disassemble, inspect, and repair various automobile units by using proper tools and
procedures: gear box, differential, brakes, suspension, steering, etc.
v. Follow safety rules for repair and maintenance of various transmission systems of
automobile vehicle.
