Drivable short-term, but fix now to avoid damage.
This code means the transmission computer found an electrical problem in the shift solenoid C circuit, such as an open, short, or out-of-range resistance. It's often caused by damaged wiring, a corroded connector, or a failed solenoid coil. Repairs usually involve testing the circuit, fixing wiring or connectors, or replacing the solenoid, and it's commonly fixable without major transmission work.
$150 – $600
Varies by vehicle and root cause.
For short trips, usually yes, but it's not ideal. An electrical fault can cause slipping or limp mode, which is unsafe in traffic, so have it checked as soon as possible.
Most repairs run $150 to $600. Fixing a wire or connector is on the cheaper end, while replacing the solenoid costs more depending on your vehicle and labor.
Yes, it's best to address it quickly. Electrical faults that affect shifting impact safety and can worsen, so treat this as a high-priority repair.
It means the issue is in the solenoid's wiring or coil rather than fluid or mechanical parts. The computer detected a circuit problem like a short, open, or bad resistance reading.
