Shift Solenoid C Malfunction
The P0760 code indicates a malfunction in the shift solenoid 'C' circuit, which is part of the transmission's hydraulic control system. This solenoid controls fluid flow to engage specific gears. When the Powertrain Control Module (PCM) detects an electrical fault (open, short, or incorrect resistance) in the solenoid circuit, it sets this code. Common causes include a faulty solenoid, damaged wiring, low transmission fluid, or internal transmission issues.
01. Most Common Causes
- Faulty shift solenoid C
- Damaged wiring or connector in solenoid circuit
- Low or contaminated transmission fluid
- Internal transmission mechanical failure
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Harsh or erratic shifting
- Transmission stuck in gear or limp mode
- Decreased fuel economy
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Check transmission fluid level and condition.
Step 3: Inspect wiring and connectors for damage or corrosion.
Step 4: Test solenoid resistance with a multimeter (specs vary by vehicle).
Step 5: Perform a transmission pressure test if needed.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended. Driving with a faulty shift solenoid can cause erratic shifting, transmission damage, or complete failure, leaving you stranded.
How much does it cost to fix?▼
Repair costs typically range from $150 to $400, including parts and labor. Solenoid replacement alone is $50-$150, but labor and diagnostics add to the total.
