This video is intended for students in the online AUSV 2520 Automatic Transmissions class at Weber State University in Ogden, Utah. This class is normally taught facetoface, but due to the COVID19 Pandemic in 2020, I am attempting to offer the class material online. Suggested quiz questions are shown below the video timeline. You should have watched the following Planetary Gear Set video first    • Planetary Gear Set Operation  AUSV 2520  

Questions for Teachers:
1. What is the function of the fluid coupling portion of a torque converter? (Why is it there?)
2. What torque converter part(s) is connected to the engine?
3. What torque converter part(s) is connected to the transmission input shaft?
4. Under what conditions are maximum heat generated inside a torque converter?
5. How is the fluid in the torque converter cooled?
6. Where does the cooled fluid go before returning to the transmission's oil pan?
7. What does stall speed mean?
8. Can stall speed be obtained while driving at freeway speeds?
9. What is the function of the Tow/Haul mode in relation to the torque converter?
10. What is the function of the torque converter clutch?
11. Is heat generated inside the torque converter when the torque converter clutch is applied?
12. How is the transmission oil pump driven?
13. What torque converter part(s) is connected to the stator shaft?
14. What is the function of the stator?
15. What are the four functions of a modern torque converter?
16. Tell me one thing you learned or found interesting in this assignment?

ABOUT US:
Weber State University (WSU) Automotive Technology Department Automatic Transmission Lab. A technical description and demonstration of the basic components and operation of a torque converter in an automatic transmission or transaxle. Components from the Allison 1000 Transmission were used in the majority of this video.

We teach current vehicle technologies to our automotive students at Weber State University and online. For more information visit: http://www.weber.edu/automotive
