Drivable short-term, but fix now to avoid damage.
This code means the transmission control module detected an intermittent (on-and-off) electrical problem in the shift/timing solenoid circuit, which controls when and how the transmission changes gears. It's often caused by a failing solenoid, corroded or loose connectors, chafed wiring, or low and dirty transmission fluid. Repairs usually start with inspecting the wiring and connectors, checking fluid, and replacing the solenoid or its harness if needed.
$150 – $700
Varies by vehicle and root cause.
For short trips you usually can, but you shouldn't rely on it. The intermittent signal means the transmission could shift harshly or drop into limp mode without warning, so get it diagnosed soon and avoid long drives until it's fixed.
It depends on the cause. A wiring or connector repair can run around 150 to 300 dollars, while replacing a shift solenoid typically lands between 250 and 700 dollars including labor. A faulty control module would cost more.
It can be. While the immediate fault is electrical and often inexpensive, ignoring it can lead to slipping, overheating, and real transmission damage that costs far more to repair, so it's worth addressing promptly.
Because it's an intermittent fault, the issue may only appear with heat, vibration, or certain gear changes. Loose connectors, partially broken wires, or a solenoid that fails only under load are common reasons the code sets and clears on its own.
