Drivable short-term, but fix now to avoid damage.
This code means the transmission computer detected an intermittent or unstable signal from shift solenoid D, meaning the fault comes and goes rather than staying constant. It usually points to a loose connector, chafed wiring, or a solenoid that's beginning to fail. It's commonly fixed by tracing and repairing the wiring or replacing the solenoid, and intermittent faults are often resolved without major transmission work.
$200 – $750
Varies by vehicle and root cause.
Often yes for a short while, but it's unpredictable. The transmission may behave normally then suddenly shift poorly or limp, so have it diagnosed soon rather than counting on it.
Repairs usually fall between about $200 and $750. Finding an intermittent wiring fault can take diagnostic time, while a solenoid replacement adds to the parts cost.
It can be. Even though the issue comes and goes, it can lead to sudden limp mode and signals a developing problem, so it's best to address it before it becomes constant.
Because the fault is intermittent, it may not be present when the car is in the shop. Technicians often need to wiggle-test wiring and connectors or monitor live data to catch it.
