P0757 — Shift Solenoid A Intermittent
Drivable short-term, but fix now to avoid damage.
What P0757 means
This code means the transmission control module detected an intermittent (on-and-off) electrical fault in shift solenoid A, which helps control gear changes. Because it comes and goes, it's often caused by loose or corroded connectors, chafed wiring, or a solenoid that's beginning to fail. Diagnosis usually involves wiggle-testing the wiring and checking the connector, then replacing the solenoid if needed.
Common symptoms
- Check engine light is on, sometimes flickering on and off
- Occasional harsh or erratic shifts
- Transmission slips intermittently
- Brief moments of being stuck in one gear
- Inconsistent or jerky acceleration
Common causes
- Loose or corroded electrical connector at the solenoid
- Chafed or intermittently shorted wiring
- Shift solenoid A starting to fail
- Low or contaminated transmission fluid
- Intermittent fault in the transmission control module
Typical repair cost
$150 – $600
Varies by vehicle and root cause.
Frequently asked questions
Can I keep driving with a P0757 code?
Usually for short trips, yes, but the intermittent nature makes it unpredictable. The transmission could shift harshly or slip without warning, so get it checked soon rather than relying on it.
How much does it cost to fix a P0757 code?
Expect roughly $150 to $600. A connector or wiring repair can be inexpensive, while a solenoid replacement or fluid service adds to the bill.
Is a P0757 code serious?
It can be. Even an intermittent shift fault can leave you in limp mode unexpectedly and may progress into a constant failure if left alone.
Why is this code intermittent?
Intermittent codes usually come from loose connections, chafed wiring, or a solenoid that only acts up under certain conditions like heat or vibration, which is why the symptoms come and go.
