A P0782 trouble code means that the Powertrain Control Module (PCM) has detected a problem with the shift function between gears 2 and 3. Some other transmission related trouble codes that can also occur alongside this code include P0780, P0781, P0783, P0784, P0785, P0786, P0787, P0788, and P0789.
What is code P0783 mean?
The P0783 code means that the PCM has detected an abnormal 3-4 shift function, which is necessary to decrease and increase speed, maximize engine performance, and optimize the vehicle’s fuel efficiency.
What is code po974?
P0974 code definition
The P0974 code is generic powertrain code related to the transmission, including pressure faults and sensor failures. In this case, the engine control module (ECM) has detected a fault with a high voltage reading from the shift solenoid A control circuit.
How do I fix code P0783?
What Repairs Will Fix P0783?
- Change the transmission fluid and filter.
- Replace faulty solenoid(s)
- Repair or replace a faulty transmission pump.
- Repair or replace defective transmission valve body.
- Transmission flush to clean passages.
- Cleaning corrosion from connectors.
- Repairing or replacing wiring.
How do I fix error code P0740?
Repairs that can fix the P0740 code may include:
- Replacing the torque converter clutch solenoid.
- Replacing the torque converter or clutch.
- Adding or replacing transmission fluid and filter.
- Replacing the powertrain control module.
- Overhauling the current transmission.
- Replacing the transmission with a brand new one.
Where is the transmission shift solenoid located?
Transmission Shift Solenoid Location
The Transmission shift solenoids are located inside the valve body of your automatic transmission. They are integrated into the valve body, and on some car models, you can see them without removing the valve body, while on others, you have to remove the valve body to reach them.
What does shift solenoid B do?
Shift solenoids open and close valves in the valve body to allow transmission fluid to reach your clutches and bands for a smooth shift. A malfunctioning shift solenoid “B” can potentially interrupt this process and cause a variety of transmission problems, which can make your vehicle undrivable.
