P0763
Shift Solenoid C Electrical
Transmission
Generic OBD-II
Medium
What it means
P0763 means the transmission control module has detected an electrical fault — an open or short — in the shift solenoid C circuit. This solenoid directs hydraulic pressure to engage a gear, so a fault can cause delayed or harsh shifts, slipping, or a drop into limp mode. The cause is often the wiring or connector rather than the solenoid itself.

Can I keep driving? Usually drivable, but expect delayed or harsh shifts and possible limp mode — repair soon to avoid transmission wear.
Common symptoms
What you'll notice
- Delayed or harsh shifting
- Transmission may stay in one gear or drop into limp mode
- Transmission slipping under load
- Reduced fuel economy
- Check-engine light on
Common causes
Most likely first
- Faulty shift solenoid C (open or shorted winding)Likely
- Damaged wiring or corroded connectors in the solenoid C circuitCommon
- Low transmission fluid level or pressureCommon
- Sticking valve body from contaminated fluidLess often
- Failed transmission control module (TCM)Less often
How to diagnose & fix
Work through it in order
- Check transmission fluid level and condition; correct if low, dirty, or burnt.
- Read freeze-frame data and inspect the solenoid C connector and wiring for damage or corrosion.
- Measure solenoid C resistance against spec and test the circuit for opens or shorts; replace the solenoid if out of range.
- If wiring and solenoid check out, inspect the valve body for sticking or debris.
- Clear the code and road-test; suspect the TCM only after the above pass.
FAQ
Quick answers
Is it safe to drive with P0763?+
Short trips are usually fine, but harsh shifting, slipping, or limp mode can add heat and wear, so repair it soon.
Can I just clear P0763?+
You can, but an electrical fault in the solenoid or its wiring will set it again, usually within a drive cycle or two.
