Drivable short-term, but fix now to avoid damage.
This code means the transmission control module detected an intermittent (on-and-off) electrical fault in shift solenoid A, which helps control gear changes. Because it comes and goes, it's often caused by loose or corroded connectors, chafed wiring, or a solenoid that's beginning to fail. Diagnosis usually involves wiggle-testing the wiring and checking the connector, then replacing the solenoid if needed.
$150 – $600
Varies by vehicle and root cause.
Usually for short trips, yes, but the intermittent nature makes it unpredictable. The transmission could shift harshly or slip without warning, so get it checked soon rather than relying on it.
Expect roughly $150 to $600. A connector or wiring repair can be inexpensive, while a solenoid replacement or fluid service adds to the bill.
It can be. Even an intermittent shift fault can leave you in limp mode unexpectedly and may progress into a constant failure if left alone.
Intermittent codes usually come from loose connections, chafed wiring, or a solenoid that only acts up under certain conditions like heat or vibration, which is why the symptoms come and go.
