List the three major components of a CVT transmission 2. What is the purpose of the forward clutch?  Use the "," and "." keys to step frame by frame through the video as necessary for the next three questions. 3. Is the CVT shown at timestamp 2.52 in under-drive, direct-drive, or over-drive mode? How can you tell? 4. Is the CVT shown at timestamp 3.29 in under-drive, direct-drive, or over-drive mode? How can you tell? 5. Is the CVT shown at timestamp 3.34 in under-drive, direct-drive, or over-drive mode? How can you tell? 6. What are some advantages of a CVT? 7. Are CVTs used in small cars or larger cars and trucks? Why? 8. What are some disadvantages of a CVT? 9. Tell me one thing you learned or found interesting in this video. ABOUT US: Weber State University (WSU) - Automotive Technology Department - Transmission Lab. GM Continuously Variable Transaxle (CVT) model VT25. How a belt-driven CVT Works. Ford, GM, Honda, Chrysler (JATCO), and Nissan CVTs are similar. CVTs allow the engine to operate at the RPM for peak efficiency while increasing and decreasing the transmission drive ratio to change vehicle speed. eCVTs are different and are demonstrated in another WeberAuto video here    • Understanding the Toyota RAV4 Hybrid   We teach current vehicle technologies to our automotive students at Weber State University and online.
