TEXTBOOK Automotive Technology A systems Approach

COURSE DESCRIPTION; A study of the operation, hydraulic principles, and related circuits of modern automatic transmissions and automatic . Diagnosis, disassembly, and assembly procedures with emphasis on the use of special tools and proper repair techniques.

COURSE LEARNING OUTCOMES; Utilizing appropriate safety procedures, the student will preform general transmission and transaxle diagnosis; preform and transaxle maintenance and adjustments, and preform in-vehicle and off-vehicle automatic transmission and transaxle repair.

PERFORMANCE OBJECTIVES: . By the end of the semester, the student will be able to perform the following tasks in the classroom and lab.

1. The student will demonstrate proper procedures involving the operation of an automotive shop to the standards of the industry and instructor.

2. The student will demonstrate knowledge of proper procedures of shop cleaning and toolroom care according to standards of the instructor and the Industrial Division.

3. The student will demonstrate knowledge of correct safety procedures in the automotive lab in accordance with shop safety and dress code standards.

4. The student will demonstrate the knowledge and the ability to service the automatic transmission to compare with manufacturer's recommended specifications.

5. Identify and accurately implement automotive nomenclature and trade terms that are used by automotive manufacturers and craftsmen in the field.

6. Identify all hand and power tools used by craftsmen of the field that are needed to

1 properly perform repairs on automotive and light duty diesel transmissions automatic and standard using shop manual procedures.

7. Show the ability to accurately measure tolerances to compare with manufacturers' recommended specifications.

8. Accurately describe the shift cycle of the automatic transmission three speed and three speed overdrive to instructor's standards.
