Drivable short-term, but fix now to avoid damage.
This code means the transmission computer detected an electrical fault in the circuit for shift solenoid D, such as a short, open, or out-of-range signal. It usually points to a failed solenoid, damaged wiring, or a corroded connector rather than a mechanical transmission problem. It's commonly fixed by repairing the wiring or replacing the solenoid, and it often doesn't require major internal transmission work.
$200 – $750
Varies by vehicle and root cause.
For short trips, usually yes, but you shouldn't rely on it. An electrical fault in the shift solenoid can cause erratic shifting or limp mode, so have it checked promptly to avoid added wear.
Repairs typically range from about $200 to $750. A simple wiring or connector fix is on the lower end, while replacing the solenoid raises the cost.
It can be. The transmission may shift poorly or limp, and ignoring it risks more damage, so it's wise to address it soon even if the car still drives.
Not always. Because it's an electrical code, the problem can also be wiring, a connector, or the control module, so a proper diagnosis is important before replacing parts.
