Drivable short-term, but fix now to avoid damage.
This code means the transmission's actual gear ratio in second gear doesn't match what the computer expects, usually a sign of slipping. It's often caused by low or degraded transmission fluid, worn clutches or bands, or a failing solenoid. Catching it early sometimes allows a fluid service or solenoid fix before more serious internal repairs are needed.
$200 – $2500
Varies by vehicle and root cause.
Short trips are usually possible, but it's not a good idea long term. Slipping in second gear can overheat and damage the transmission, so limit driving and get it checked soon.
It ranges widely. A fluid service or solenoid replacement may cost $200 to $600, but internal clutch or band repairs can run $1,500 to $2,500 or more depending on the transmission.
Yes, it can be. It signals the transmission is slipping in second gear, and ignoring it risks expensive internal damage, so it deserves prompt attention.
Absolutely. Low or worn-out fluid is one of the most common and cheapest causes, so checking and servicing the fluid is often the first step in diagnosis.
