Introduction to automatic transmission and transaxles. Students will learn theory,
diagnosis and repair of automatic drivetrain components used on today’s light duty
vehicles. Subjects covered in this course are; torque converters, planetary gearsets,
hydraulic systems, electronic controls, valve bodies and CVT’s. Students will learn
to use specialized equipment necessary to diagnose and repair automatic transmissions
and transaxles. This class is structured to provide competency-based application of
NATEF automotive repair tasks in a working shop environment. This course will help
the student in taking the ASE technician certification examinations.

Students are responsible to be on time to class and will clock in and out each day. Each
accumulated five "lates" will result of subtraction of 6 hours (1 instructional day) from
the total 1750 hours required to graduate the program.
Student assessment will be documented by weekly quizzes, tests and practical application
exercises. A final test will be given at quarter completion. Students will be allowed to
discard their lowest (one) test score, which will not be calculated into the overall average.
Students absent on the day the test is given will not be allowed to make up the test.
Students will be advised of areas where improvements are needed on an ongoing basis.
All written work will be graded on a percentage of correct answers as follows:
Plan on studying a minimum of 2 hours per weeknight. Students will be required to
complete all homework assignments in a timely manner. Late work will not be accepted.
Student grades will be computed at the completion of each quarter for all courses;
AMM145 through AMM245 in the evaluation areas noted in "Evaluation Devices" noted
above. Advanced Auto Mechanics (AMM247) and Special Problems (AMM199) will be
evaluated on performance objectives. Leadership (AMM299) will be evaluated on
performance objectives and the students daily work log.
A 100-93 4.0 Point
A- 92-90 3.7 Point
B+ 89-88 3.3 Point
B 87-84 3.0 Point
B- 83-80 2.7 Point
C+ 79-77 2.3 Point
C 76-73 2.0 Point
BELOW 2.0 GPA:
C- 72-70 1.7 Point
D+ 69-67 1.3 Point
D 66-60 1.0 Point
F <60 0.0 Point
Each unit is designed with the intent that you will master specific NATEF
tasks/competencies that you will be required to perform in the shop/lab. These are
designated as unit performance objectives/competencies. Each performance
objective/competency is broken down into steps that enable you to perform the task. You
will receive a rating score between 0 and 4 on each of the competencies based on the
appropriate criteria scale:
Level 1 Exposure 1 = score of 60%
Level 2 Requires close supervision 2 = score of 70%
Level 3 Performs with limited supervision 3 = score of 80%
Level 4 Completes task independently 4 = score 90%
At course completion, your rating scores will be averaged together combined with the
designated evaluation devices to give you one final grade for the quarter.
OTHER SPECIAL INSTRUCTIONS/INFORMATION: All Students will be required
to posses a valid driver's license to remain in the program. If you lose your driver's
license for any reason, you will be allowed to finish the quarter and upon proof of valid
driver's license, will be able to re-enter at a later date.
LEARNING OUTCOMES EXPECTED OF STUDENTS AT THE COMPLETION
