AST 1095 - Automatic Transmissions Credits: 4
Hours/Week: Lecture 1Lab 6
Course Description: This course covers automatic transmission theory, sub-assembly operation, and operational controls. Rebuilding techniques, service procedures and diagnosis are covered in group discussions and shop applications. Students must be able to perform physical tasks to complete course requirements.
Prerequisite(s): Concurrently enrolled in AST 1005 , AST 1055 , AST 1065 , AST 1075 , and AST 1085 . Assessment score placement in RDNG 0950 or above or completion of RDNG 0900 with a grade of C or higher; assessment score placement in ENGL 0090 or above or completion of ENGL 0080 with a grade of C or higher; Arithmetic assessment score of 64 or higher or elementary algebra assessment score of 76 or higher OR assessment score/ACT score placement into MATH 0070 or above OR completion MATH 0030 or MATH 0060 with a grade of C or higher.
Recommendation: We strongly encourage students who score below 64 to meet with an advisor or counselor to discuss their review and course options PRIOR to Math assessment retesting or registering for a MATH course.
