AMS3137 AUTOMATIC TRANSMISSIONS
5 Credit Hours
This course is open to students on the college level in either the freshman or sophomore year and to area high school vocational students.
AMS3137 - Automatic Transmissions I (5 hrs.)
This course will enable the student to gain basic understanding and hands on experience utilizing industry standard procedures in the diagnosis and repair of the automatic transmission and transaxle systems. Topics presented throughout the course cover diagnoses, removal, repair, and installation of automatic transmissions and transaxles, both on and off the vehicle, including the disassembly of oil pumps, converters, gear trains, shafts, bushings, cases and friction and reaction units.
This course is designed to help the student increase their knowledge concerning entry-level skills contained in the sequenced competencies, for success, after graduation from the Automotive Technology Program.
Upon completion of this course, the student will be able to identify the principles and procedures needed for diagnosis and repair of automatic transmissions.

Based on classroom occupancy.
Course Time Frame:
The U.S. Department of Education, Higher Learning Commission and the Kansas Board of Regents define credit hour and have specific regulations that the college must follow when developing, teaching and assessing the educational aspects of the college. A credit hour is an amount of work represented in intended learning outcomes and verified by evidence of student achievement that is an institutionally-established equivalency that reasonably approximates not less than one hour of classroom or direct faculty instruction and a minimum of two hours of out-of-class student work for approximately fifteen weeks for one semester hour of credit or an equivalent amount of work over a different amount of time. The number of semester hours of credit allowed for each distance education or blended hybrid courses shall be assigned by the college based on the amount of time needed to achieve the same course outcomes in a purely face-to-face format.
