P0780 — P0780 — Shift Malfunction
Drivable short-term, but fix now to avoid damage.
What P0780 means
P0780 is a general shift malfunction code, meaning the transmission control module detected that a commanded gear change didn't happen correctly. It often appears alongside more specific solenoid or gear-ratio codes. The result is poor or unpredictable shifting that should be diagnosed before it gets worse.
Common symptoms
- Erratic, harsh, or missed gear shifts
- Transmission slipping
- Stuck in a single gear or limp mode
- Hesitation or jerking during shifts
- Check engine light on
Common causes
- Faulty shift solenoids
- Low or contaminated transmission fluid
- Valve body problems or stuck valves
- Worn internal clutches or bands
- Wiring or connector faults
- Faulty transmission control module
Typical repair cost
$150 – $2500
Varies by vehicle and root cause.
Frequently asked questions
Can I drive with a P0780 code?
Only carefully and not for long. The transmission isn't shifting reliably, so driving it can cause more wear or leave you stuck in gear. Get it to a shop before relying on it daily.
How much does it cost to fix P0780?
A solenoid or fluid repair may be $150-$600, but if internal clutches or the valve body are involved, the cost can climb toward $1,500-$2,500 or more.
Is P0780 serious?
Yes, it's high severity. A general shift malfunction means the transmission isn't doing its job correctly, and ignoring it can lead to expensive internal damage.
Why does P0780 often come with other codes?
P0780 is a broad shift-fault code, so the computer usually stores more specific codes (like a solenoid or gear-ratio code) that pinpoint the real cause. Those help the technician fix the underlying problem.
