The P0980 diagnostic trouble code is an indication that there is an issue with the shift solenoid C control circuit.
Shift solenoids and speed sensors are used in an automatic transmission to change gears. The transmission control module (TCM) collects information from the speed sensors and sends a signal to the shift solenoids indicating whether an upshift or downshift is necessary. The transmission control module (TCM) constantly monitors the shift solenoids and speed sensors and will perform resistance checks to ensure they are working properly. If the resistance check performed by the transmission control module (TCM) is not within the predetermined specification the faulty shift solenoid will be disabled, the P0980 diagnostic trouble code will be stored, and the check engine light will come on indicating there is a problem.
A diagnostic trouble code is normally considered serious when it causes driveability issues or a change in performance. Severe driveability problems will exist while this code is stored in the powertrain control module (PCM). It may also be impossible to operate the vehicle at all. For this reason, the P0980 diagnostic trouble code is considered extremely serious and should be diagnosed and repaired as soon as possible.
Repair or replace shift solenoid wiring that is frayed, broken, or shorted
Repair or replace shift solenoid connectors that are damaged or corroded
Replace or rebuild faulty transmission
Replace faulty transmission control module (TCM)
If the shift solenoid is located on the outside of the transmission, this tends to be an easy fix. Internal shift solenoids are more difficult to fix and sometimes require removing the transmission from the vehicle. At times, the best fix for the P0980 diagnostic trouble code is to replace the transmission.
