The speed-sensitive signal to the control valve body is provided by which hydraulic pressure?

Explanation:
The pressure that serves as the speed-sensitive signal to the control valve body is governor pressure because the governor is designed to generate hydraulic pressure that increases with vehicle speed, providing a proportional input to the valve body to control shift points and line pressure. Main pressure is the system’s overall supply and isn’t inherently tied to speed, while modulator pressure and MPRV pressure relate to other functions and relief actions rather than signaling speed to the valve body.
