P0763 Code: Shift Solenoid C Electrical
🟠 Moderate severity · drivable
Drivable, but shifting may be harsh or erratic and continued driving can damage the transmission. Fix it soon.
What P0763 means
There is an electrical fault in the shift solenoid C circuit — the computer can't control the solenoid even though the solenoid itself may be mechanically fine. The problem is usually in the wiring, the connector, or the computer's solenoid driver.
Symptoms
- Check engine light on
- Harsh or erratic shifting
- Transmission may be stuck in one gear
- Possible limp mode
Common causes
- most common: Damaged wiring or loose connector at the solenoid
- common: Faulty shift solenoid C (internal electrical fault)
- less common: Transmission control module (TCM) driver fault
How to fix it
| Fix | DIY? | Typical cost |
|---|---|---|
| Inspect and repair the solenoid wiring and connector | Yes | $10–60 |
| Replace the shift solenoid C | Mechanic | $200–500 |
Frequently asked questions
Is an "electrical" code different from a "stuck" code?
Yes. Electrical means the circuit or computer driver is at fault; stuck on/off means the solenoid is mechanically held in one position.
What should I check first?
The wiring and connector at the solenoid — loose or corroded connections are the most common electrical cause.
How much does it cost to fix?
$10–60 for a wiring repair, or $200–500 for a new solenoid.
