P0980
Shift Solenoid C Control Circuit High
Transmission
Generic OBD-II
Medium
What it means
P0980 means the transmission control module has detected a high-voltage condition (an open or short to power) in the control circuit for shift solenoid 'C'. That solenoid helps engage and release specific gears, so the fault can cause erratic or delayed shifts, slipping, or a protective limp mode. It's an electrical circuit fault rather than internal mechanical damage.
Medium
Can I keep driving? Usually driveable, but erratic shifting or a stuck-gear limp mode can strain the transmission — get it fixed before long trips.
Common symptoms
What you'll notice
- Improper or erratic gear shifting
- Delayed or prolonged shifts
- Slipping or inability to engage certain gears
- May default to limp/failsafe mode
- Check-engine light on
Common causes
Most likely first
- Open or short-to-power in the shift solenoid 'C' circuitLikely
- Failed shift solenoid 'C'Common
- Damaged wiring or corroded connectorsCommon
- Failed transmission control module (TCM)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and check transmission fluid level and condition.
- Inspect the solenoid 'C' wiring and connector for opens or a short to power.
- Measure the solenoid resistance against spec; replace if out of range.
- Repair the high-voltage circuit fault, then clear and road-test.
- If wiring and solenoid are good, suspect the TCM.
FAQ
Quick answers
Is it safe to drive with P0980?+
Short trips are usually fine, but erratic shifting and limp mode add wear, so repair it promptly.
Can I just clear P0980?+
It returns until the circuit fault or solenoid is repaired; the transmission may keep entering failsafe mode.
