Which condition is NOT typically associated with low transmission fluid?

Low transmission fluid can lead to a variety of issues within a vehicle's transmission system, but it does not typically result in excessive fuel efficiency. When transmission fluid levels are low, the transmission may struggle to perform effectively, which often results in poor shifting, strange noises (like grinding or whining), and can even cause the gears to catch or slip during operation.

In contrast, excessive fuel efficiency is generally not a consequence of low transmission fluid. In fact, low fluid levels can lead to less efficient power transfer and strained engine performance, which usually leads to decreased fuel efficiency rather than an increase. Thus, the correct choice highlights a condition not typically associated with the problems arising from low transmission fluid levels.
