Drivable short-term, but fix now to avoid damage.
This code means the transmission control module sees that shift solenoid B isn't performing correctly or appears stuck in the off position, so commanded gear changes don't happen as expected. It's often caused by a stuck or failed solenoid, debris from dirty fluid, or wiring and connector faults. Repairs usually involve a fluid service, cleaning or replacing the solenoid, and checking the circuit.
$150 – $650
Varies by vehicle and root cause.
Short trips are usually possible, but not wise. The transmission may not reach certain gears or may stay in limp mode, and continued driving can cause further damage. Get it diagnosed soon.
Most repairs land between $150 and $650. A fluid service and solenoid replacement are common, while valve body or wiring repairs can push the cost up.
Yes. A stuck-off solenoid can keep the transmission from shifting properly and, if ignored, may lead to expensive internal damage, so it deserves prompt attention.
It means the solenoid isn't opening or activating when commanded, often due to debris, wear, or an electrical fault, so it can't direct fluid to make the right gear changes.
