Code Solutions P0980.
1. Inspect the wiring and connectors related to the shift solenoid “C” to check for any signs of damage, corrosion, or loose connections. Repair or replace any damaged components as needed.
2. Test the shift solenoid “C” with a multimeter to ensure it is functioning properly. Replace the solenoid if it is found to be faulty.
3. Check the transmission fluid level and condition. Low or dirty transmission fluid can cause shift solenoid issues. Top up or replace the fluid as necessary.
4. Clear the trouble codes in the vehicle’s computer system using a scan tool. Drive the vehicle and monitor if the P0980 code returns. If it does, further diagnosis may be needed.
5. Reset the transmission control module by disconnecting the battery for a few minutes and then reconnecting it. This may help in clearing any temporary issues causing the high shift solenoid “C” control circuit code.
