How Car Transmissions Work: Manual, Automatic, and Cvt

How Car Transmissions Work: Manual, Automatic, and Cvt is a free, self-paced learning path in Engineering & Robotics, written at General Public / 9th Grade reading level. Across 15 structured stations, you will work through the core ideas step by step, each with a short quiz to check your understanding. By the end you will be able to identify the relationship between torque plus rotational speed; calculate gear ratios for basic mechanical systems; analyze engine speed requirements during operation.
