What does a governor pressure sensor do?

What does a governor pressure sensor do?

Governor Pressure Electronic transmissions use the vehicle speed sensor signal for vehicle speed. Governor pressure causes a transmission to upshift, and throttle pressure causes it to downshift. Governor pressure works on one end of the valve, and a spring assisted by throttle pressure works on the other.

What does the governor pressure sensor and solenoid do?

Governor pressure sensors and solenoids help keep automatic transmissions running smoothly. For that reason, the governor pressure sensor and solenoid repair kit is also known as an auto transmission governor repair kit.

How much does it cost to replace a pressure control solenoid?

The average total cost to diagnose and replace one ranges between $150 and $400. Depending on the make and model of your vehicle, expect to pay between $15 – $100 for a single transmission shift solenoid. A pack can cost $50 to $300.

What would be noticed when a good shift solenoid is activated?

Those engine sensors determine when it’s time to shift gears based on speed. When the shift solenoid is activated, the plunger will open certain valves in the valve body to allow transmission fluid to enter. That puts pressure on the clutches and bands that cause the transmission to actually shift gears.

What affects shift valves to cause a downshift?

As vehicle speed increases, the governor pressure (affected by vehicle speed) increases until it overcomes throttle pressure and causes an upshift. A downshift occurs when throttle pressure overcomes governor pressure. This is because of the increased engine load. These two pressures control shift valve movement.

What is code P1762?

P1762 Governor Pressure Sensor Offset Volts Too Low Or High.

What is code P1763?

P1763 Governor Pressure Sensor Volts Too High.

Where is the pressure control solenoid located?

In most cases, solenoids are located inside of the oil pan, connected to the valve body. Depending on what you drive, the technician may be able to replace just the failed shift solenoid.
