P0768 — Shift Solenoid C Intermittent
Drivable short-term, but fix now to avoid damage.
What P0768 means
This code means the transmission computer detected an on-and-off problem with shift solenoid C, so the fault comes and goes rather than staying constant. It's often caused by a loose or corroded connector, intermittent wiring, or a solenoid that's beginning to fail. Repairs usually start with inspecting connectors and wiring, then testing or replacing the solenoid, and intermittent issues are typically fixable without a rebuild.
Common symptoms
- Check engine light comes and goes
- Occasional slipping or harsh shifts
- Transmission sometimes drops into limp mode
- Intermittent delayed gear changes
- Inconsistent or erratic shifting
Common causes
- Loose or corroded electrical connector
- Intermittent break or chafe in the wiring
- Shift solenoid C starting to fail
- Low or contaminated transmission fluid
- Faulty transmission control module
Typical repair cost
$150 – $600
Varies by vehicle and root cause.
Frequently asked questions
Can I keep driving with a P0768 code?
Short trips are usually okay, but the unpredictable shifting can catch you off guard in traffic. It's best to have it diagnosed soon before the fault becomes constant.
How much does it cost to fix a P0768 code?
Repairs typically range from $150 to $600. Cleaning or repairing a connector is cheaper, while replacing the solenoid costs more depending on the vehicle.
Is a P0768 code serious?
It's worth prompt attention. Even an intermittent shifting fault affects safety and tends to get worse, so don't ignore it just because it isn't constant.
Why is P0768 harder to diagnose?
Because the fault is intermittent, it may not be present when the car is tested. Technicians often have to inspect wiring and connectors carefully or recreate the conditions to catch it.
