In relation to an automatic transmission in a mobile water supply (MWS) apparatus, which statement is NOT true?

In a mobile water supply apparatus, automatic transmissions are designed to shift gears automatically based on the vehicle's speed and engine load. This feature allows the driver to focus more on the operation of the vehicle and its surroundings rather than constantly adjusting gears, which is a significant advantage in dynamic driving conditions often encountered in emergency scenarios.

Regarding the other statements, it is important to understand that while automatic transmissions can handle many driving conditions effectively—though certain challenging off-road conditions may still require driver intervention—they do indeed provide manual gear selection options in many modern vehicles. This allows a driver to override the automatic system when needed, offering versatility. Additionally, one of the primary benefits of automatic transmissions is that they require less driver input compared to manual transmissions, making vehicles easier to operate, especially during high-stress situations like firefighting.

By asserting that automatic transmissions cannot shift gears automatically, the statement misrepresents their fundamental function and purpose, which is to enhance the driving experience through automation and efficiency.
