Drivable short-term, but fix now to avoid damage.
This code means the output speed sensor signal is dropping out intermittently, so the transmission control module loses reliable speed data on and off. It's most often caused by loose or corroded connectors, chafed wiring, or a sensor that's beginning to fail. Repairs usually involve carefully inspecting the wiring and connectors and replacing the sensor, and it's typically fixable without major transmission work.
$150 – $450
Varies by vehicle and root cause.
For short trips, usually yes, but it's risky because the fault is unpredictable. The transmission could drop into limp mode without warning, so get it checked soon.
Expect roughly $150 to $450. Intermittent faults can take extra diagnostic time to trace bad wiring or connectors, which may add to the labor cost.
It can be, mostly because it's unpredictable. The signal cutting in and out can cause sudden rough shifts or limp mode, so it's worth fixing promptly.
Because the fault only appears now and then, the problem may not show up while the technician is testing. They often have to wiggle-test wiring and connectors to catch it.
