Planetary Gear Set Operation - 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.
