Loss of governor pressure would cause which symptom?

Loss of governor pressure would cause which symptom?

• A. High main pressure
• B. No upshifts
• C. No downshifts
• D. Low main pressure

Answer: (B)

Governor pressure serves as the hydraulic signal that prompts upshifts as vehicle speed increases. If that pressure is lost, the transmission cannot reach the threshold that triggers shifting to higher gears, so it stays in the lower gear and there are no upshifts. This doesn’t directly cause high or low main hydraulic pressure, and downshifts are driven by other signals, not the loss of governor pressure.
