This summary uses the existing diagnostic information shown in full below.
Your car's computer is having trouble controlling a part that helps change gears. It's like when a remote control can't make the toy car move because the signal is too strong.
The P0980 code indicates that the transmission control module has detected a high voltage condition in the shift solenoid C control circuit.
The shift solenoids in an automatic transmission are responsible for controlling the flow of transmission fluid to change gears. The 'C' solenoid is one of these solenoids, and a 'high' signal means that the voltage in its control circuit is higher than expected. This can indicate an electrical issue such as a short circuit or a problem with the solenoid itself.
• Harsh or erratic shifting
• Transmission stuck in one gear
• Check Engine Light illuminated
• Faulty shift solenoid C
• Wiring issues such as short circuits or damaged wires
• Malfunctioning transmission control module (TCM)
Shift Solenoid: A component that controls the flow of transmission fluid to change gears.
Transmission Control Module (TCM): An electronic component that controls the operation of the transmission.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors to the shift solenoid C for damage.
• Test the shift solenoid C for proper operation.
• Repair or replace damaged wiring or connectors.
• Replace the faulty shift solenoid C.
• Reprogram or replace the transmission control module if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Honda Accord
• Toyota Camry
• Ford F-150
• Regular transmission fluid changes
• Routine inspection of transmission wiring
• Avoiding harsh driving conditions
Transmission Control Issue
• Avoid driving until the issue is diagnosed to prevent further damage.
• Consult a professional mechanic for a thorough inspection.
Transmission components may be covered under powertrain warranty; check with your vehicle manufacturer.
This code has been associated with electrical issues in transmission systems, particularly in vehicles with high mileage.
Moderate – Addressing this issue promptly can prevent further transmission damage.
Driving with transmission issues can lead to unsafe driving conditions. Address the issue as soon as possible.
• Vehicle at operating temperature
• Transmission in drive
The shift solenoid C is located inside the transmission, usually accessible by removing the transmission pan.
Q: Can I drive with a P0980 code?
A: It's not recommended to drive with this code as it can cause further damage to the transmission.
Q: How serious is the P0980 code?
A: While not immediately critical, it should be addressed soon to avoid transmission damage.
