Answer:
In manual transmissions, the driver has full control over gear shifting, allowing for precise control of acceleration and deceleration on mountain roads.
Automatic transmissions, on the other hand, shift gears automatically, making it easier for drivers to focus on navigating the mountain roads without worrying about gear changes.
Step-by-step explanation:
Manual transmissions provide better engine braking, which can be advantageous when descending steep mountain roads, whereas automatic transmissions may require the use of additional braking techniques.
