Drivable short-term, but fix now to avoid damage.
This code means the transmission control system detected a fault completing the shift between 4th and 5th gear. It's commonly caused by a faulty shift solenoid, low or dirty transmission fluid, or worn internal clutches, with wiring and control module problems also possible. Fixes range from a simple fluid service or solenoid replacement to more extensive internal transmission repair.
$150 – $2500
Varies by vehicle and root cause.
For short distances, usually yes, but don't rely on it. The transmission can be damaged further if you keep driving with shift problems, so get it inspected soon and avoid extended highway or heavy driving.
It depends on what's wrong. A fluid service or solenoid replacement may cost a few hundred dollars, while internal transmission repairs can run well over two thousand dollars.
Yes. While the car may still drive, a shift malfunction can lead to costly transmission damage if left unaddressed, so it's a higher-priority repair.
If the transmission can't shift into 5th gear, the engine stays at higher RPM at highway speeds. This hurts fuel economy and means the transmission isn't reaching its top gear until the fault is fixed.
