Torque Converter Operation and Components - AUSV 2520

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 face-to-face, but due to the COVID-19 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 https://youtu.be/5piYEX-jRt4

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.
