What Does P0767 Mean?
The electrical circuit for Shift Solenoid C has a fault. The TCM has detected an abnormal voltage condition in the solenoid C wiring, such as an open circuit, short to ground, or short to battery voltage. This purely electrical fault prevents the TCM from properly controlling solenoid C, directly impacting gear selection.
Common Causes
35%
Open or short circuit in the shift solenoid C wiring harness
30%
Shift solenoid C internal coil failure (open or shorted)
20%
Corroded or damaged transmission connector disrupting solenoid C circuit
10%
TCM internal solenoid driver circuit failure
5%
Solenoid pack ground circuit fault
Diagnostic Steps
1
Measure solenoid C resistance at the transmission connector — an open or near-zero reading confirms a coil failure.
2
Check for voltage supply and TCM drive signal at the solenoid C pins with the key on.
3
Inspect the external transmission harness connector for corroded, bent, or pushed-back pins.
4
Perform continuity and short-to-ground tests on the solenoid C circuit from TCM to transmission.
5
If wiring is intact and solenoid resistance is out of spec, replace shift solenoid C.
Estimated Repair Cost

The most common cause of P0767 (Shift Solenoid C Electrical) is: Open or short circuit in the shift solenoid C wiring harness
Typical repair costs for P0767 range from $150 to $900, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Expect limp mode with limited gear selection. Driving at reduced speed to a repair facility is generally safe, but normal driving should be avoided.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P0767 to identify the root cause.
