Drivable short-term, but fix now to avoid damage.
This code means the transmission control module detected a general shift malfunction, where commanded gear changes aren't happening correctly. It can be caused by faulty shift solenoids, low or dirty transmission fluid, internal mechanical wear, or electrical problems. Typical fixes range from servicing the fluid and replacing solenoids to repairing wiring or, in worse cases, internal transmission work.
$200 – $1500
Varies by vehicle and root cause.
It's best to keep driving to a minimum. A shift malfunction can leave you stuck in one gear or cause slipping, so get it diagnosed quickly to avoid bigger transmission damage.
Costs vary widely, from about $200 for a fluid service or solenoid up to $1,500 or more if internal transmission repair is needed.
Yes, it's serious. A general shift malfunction affects how the transmission operates and can lead to expensive repairs if ignored, so prompt attention is important.
Not always. Sometimes it's caused by low fluid, a bad solenoid, or wiring, so a proper diagnosis is key before assuming the worst.
