Which of the following indicates low governor pressure in an automatic transmission?

The indication of low governor pressure in an automatic transmission is most accurately represented by the failure to upshift after selecting low gear. In an automatic transmission, the governor pressure plays a crucial role in regulating the shift timing and smoothness. When this pressure is low, it can lead to issues such as the transmission not receiving the necessary signals to shift up from a lower gear when the engine reaches the appropriate RPM range.

This specific failure to upshift signifies that the system is not able to properly engage the higher gears due to inadequate fluid pressure, which is integral for effective transmission operation. Maintaining proper governor pressure ensures that shifts occur at the right times and under optimal conditions, preventing unnecessary strain on the transmission components.

Failure to downshift at high speeds, slipping during acceleration, and delayed engagement during gear shifts can often relate to other mechanical issues or fluid-related problems within the transmission system. These symptoms might suggest varying problems, such as a malfunctioning throttle valve or issues with the transmission fluid's condition, but they do not specifically indicate low governor pressure like the inability to upshift from low gear does.
