Code P0983 Description
The P0983 code indicates that there is a problem with the Shift Solenoid 'D' Control Circuit being too high. The shift solenoid is responsible for regulating the flow of transmission fluid to activate gear changes in an automatic transmission. When the control circuit is reading as high, it means that there is an electrical issue causing the solenoid to stay open or closed when it shouldn't be, leading to improper gear shifting.
Common Causes of P0983
- Faulty shift solenoid 'D'
- Wiring issues or short circuits in the control circuit
- Corroded or damaged connectors
- Low transmission fluid levels
- Faulty transmission control module
Symptoms of P0983
- Harsh or delayed shifting
- Slipping gears
- Vehicle stuck in one gear
- Illumination of the Check Engine Light
- Decreased fuel efficiency
How to Fix P0983
- Begin by diagnosing the issue by using a scan tool to read the code and identify the specific cause of the problem.
- Inspect the wiring and connectors for any damage or corrosion, repairing or replacing as needed.
- Test the shift solenoid 'D' to determine if it is functioning properly, replacing it if necessary.
- Check the transmission fluid levels and top off if low, ensuring it is at the correct level.
- Clear the diagnostic trouble codes and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P0983
The cost to repair a Shift Solenoid 'D' Control Circuit High issue can vary depending on the specific cause of the problem and the labor rates in your area.
