AST 1095 - Automatic Transmissions Credits: 4
Hours/Week: Lecture 1 Lab 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. This course requires completion of or to be concurrently enrolled in AST 1005 , AST 1055 , AST 1065 , AST 1075 , and AST 1085 .
Prerequisite(s): Course placement into ENGL 0950 and RDNG 0950 or above OR completion of RDNG 0940 with a grade of C or higher OR course placement into ESOL 0051 and ESOL 0052 and ESOL 1033 OR completion of ESOL 0041 with a grade of C or higher and ESOL 0042 with a grade of C or higher and ESOL 0043 with a grade of C or higher; AND Arithmetic placement score of 64 or higher or elementary algebra placement score of 76 or higher or minimum placement score/ACT score placement into MATH 0070 or above or completion of MATH 0030 or MATH 0060 with a grade of C or higher AND instructor consent. 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 placement retesting or registering for a MATH course.
