How do modern manual transmissions differ from older designs?

Modern manual transmissions incorporate advanced technologies that significantly enhance their performance, efficiency, and usability. One such technology is the synchronizer, which facilitates smooth gear shifts by matching the speed of the gears during engagement. This eliminates grinding and improves the overall driving experience, making it easier for the driver to switch gears without needing to match RPMs precisely.

The use of synchronizers contrasts with older manual designs, which often required more skill and attention from the driver to shift smoothly. This improvement not only makes driving more accessible for those without extensive experience but also contributes to the longevity of the transmission by reducing wear on the components.

While it is true that some older designs may have had fewer features that improved efficiency and usability, the introduction of these advanced technologies in modern transmissions has led to higher performance levels and better fuel efficiency, making option B the clear choice.
