What does a governor pressure sensor do in a transmission?
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 may cause hard shifting?
Causes of rough shifting include: Transmission Fluid Low or Poor Condition – Vehicles low on transmission fluid or that are operating with worn out or contaminated fluid are likely to experience hard shift conditions.
What is governor pressure is and what is the purpose of a governor?
The pressure governor receives a signal from a pressure transducer mounted on the discharge side of the pump. As the transducer senses a change in pressure, the pressure governor sends a signal to the engine ECU to increase or decrease engine speed to maintain the desired discharge pressure.
Why is my truck having a hard time shifting?
Transmission Fluid Low or Poor Condition – Vehicles low on transmission fluid or that are operating with worn out or contaminated fluid are likely to experience hard shift conditions. Lack of adequate lubrication within the transmission can cause several problems, including hard shifting.
Can a bad torque converter cause hard shifting?
Yes, it can. A malfunctioning torque converter will not function efficiently and may cause hard shifting of your manual transmission when you shift gears. When the torque converter slips out of gear or delays a shift, it is often because the torque converter’s fin or bearing is damaged.
How do I know if my transmission pressure sensor is bad?
Top Signs of a Failing Transmission Position Sensor
- Car fails to move out of park. When your vehicle is unable to shift out of neutral or park, this is a clear indication that there is a serious problem somewhere in the transition system.
- Transmission shifts into the wrong gear.
- Vehicle becomes locked in a single gear.
What causes transmission not to shift into overdrive?
Possible causes of no overdrive include a faulty transmission range switch, valve body, faulty overdrive brake, or faulty ECM. Faults codes should be read out with a scanner, and statuses read.
What happens when a pressure control solenoid goes bad?
A bad or failing transmission pressure control solenoid can cause slipping, which can result in the transmission overheating. If left unrepaired, the slipping will ruin (burn or fry) the friction clutches and bands causing transmission failure.
