  1. Instructor won’t stop droning on! Too Much Information! Automatic Transmissions ZZZ • Students have all the basic knowledge they need • Last subject I teach this year Boring Lecture!

  2. Automatic TransmissionsAre you ready to discover and explore?! NEW! • Flipped Classroom: How does that fluid filled thing called a torque converter work? • Graphic Organizer: What a strange Rubik’s Cube this planetary gear set is! • WebQuest: What sorcery is behind shifting an automatic transmission?

  3. Flipped Classroom: How does that fluid filled thing called a torque converter work? • Students will be able to identify torque converter parts, describe its operation, as well as diagnose torque converter failures.

  4. The Task Set Before You: • Watch some TV!* • http://www.youtube.com/watch?v=EqPQln_gpdc • http://www.youtube.com/watch?v=wrGGCTkpND4 • http://www.youtube.com/watch?v=QOjHd45kecA • http://www.youtube.com/watch?v=q2fRCITXn4o Optional: • http://www.youtube.com/watch?v=29-9LRtkGTM *All TV watching to be done on students own time in the comfort of their house with popcorn.

  5. Now Start Implementing!* • Label a torque converter diagram with part names. • Draw a table showing which parts are similar to clutch components. • Brainstorm advantages and disadvantages of a torque converter. • Trace the path of vortex and rotary fluid flow. • Trace fluid flow through the stator at lock up and freewheeling. • Answer some questions. *All implementing to be done on classroom time under the guidance of their instructor with popcorn. ̽ ̽All popcorn to be provided by the student.

  6. Label Parts

  7. Coupling Speed Is the stator locked or freewheeling? _____________ Stall Speed Is the stator locked or freewheeling? _____________

  8. So... has the mystery been revealed? • Informal evaluation of student will be through their final question answers. • Formal evaluation of student will be through their torque converter test.

  9. 2. Graphic Organizer: What a strange Rubik’s Cube this planetary gear set is! • Students will be able to identify and compare the 8 possible outputs from a planetary gear set.

  10. Get Graphic Organizing! Include for the 8 different gear set scenarios : • What is held, driven and drive? • Is it forward or reverse? • Is it overdrive or reduction? • Is it usable or not? • Is it maximum overdrive or maximumreduction? Mandatory Bonus Learning: Calculate the actual gear ratios with teeth numbers given & include a drawing representing the size of gears involved.

  11. So... did you solve the puzzle? • Student’s graphic organizer will be evaluated based on a rubric.

  12. WebQuest: What sorcery is behind shifting an automatic transmission? • Students will be able to implement the knowledge of automatic transmission shifting they have learned to be able to diagnose and repair an improperly shifting transmission.

  13. Your Quest, Should You Choose to Accept It*: • Follow the automatic transmission shifting WebQuest • Read the WebQuest and select a group or work alone. • Watch linked videos and webpages to gain understanding of shift control. • Read description and operation for transmission specific information. • Prepare a graphic organizer of all the ECM and TCM inputs and outputs involved in shifting. • Answer questions on how this transmission shifts. • Look at the DTC list for shift solenoids. • Pick one DTC and explain it to the class (use rubric for required information). • Highlight on the electrical schematic the steps in the diagnostic flow chart. • Go through case study of improperly shifting transmission. *FYI, if you don’t accept it you will most likely fail the course.

  14. So... did you slay the dragon? • Informal evaluation through presentation of graphic organizer (rubric for grading) • Informal evaluation through transmission shifting questions • Formal evaluation through case study (rubric for grading) • Diagnostic steps • Correct diagnosis • Correct repair
