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. • Questions for teachers: • 1. What are the three main pieces of a simple planetary gear set? • 2. How many underdrive gear ratios are possible with a simple planetary gear set? • 3. How many overdrive gear ratios are possible with a simple planetary gear set? • 4. How many reverse gear ratios are possible with a simple planetary gear set? • 5. How many direct gear ratios are possible with a simple planetary gear set? • 6. How many usable/practical gear ratios are possible with a simple planetary gear set? • 7. How is power typically transferred through a simple planetary gear set? • 8. How does the parking gear keep the vehicle from rolling in the park position? • 9. What does the term Compound simple planetary gear set mean? • 10. What is the function of the clutch packs in the Allison 1000? • 11. What component in a transmission causes clutch packs to apply? • 12. What component controls the valves in the valve body? • 13. What component controls the electronics in the valve body? • 14. Use the Allison 1000 clutch application chart download from below for the remainder of the questions • 15. Which clutches are used to provide first gear? Choose two: C1, C2, C3, C4, C5 • 16. Which clutches are used to provide second gear? Choose two: C1, C2, C3, C4, C5 • 17.
