Shift Solenoid C Stuck Off - Transmission Performance Issue
The P0761 code indicates that the Powertrain Control Module (PCM) has detected a malfunction in the shift solenoid 'C' circuit. This solenoid controls hydraulic pressure to engage a specific gear (usually 3rd or 4th gear depending on the transmission design). When the solenoid is stuck off, it fails to apply hydraulic pressure, causing the transmission to skip that gear or operate in a default limp mode. This can lead to harsh shifting, poor acceleration, and reduced fuel economy.
01. Most Common Causes
- Faulty shift solenoid C
- Low or dirty transmission fluid
- Wiring or connector issues in the solenoid circuit
- Internal transmission mechanical failure
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Transmission stuck in gear or fails to shift
- Harsh or delayed shifts
- Reduced fuel economy
03. Step-by-Step Diagnosis
Step 1: Scan for codes and verify P0761 is present.
Step 2: Check transmission fluid level and condition; top off or replace if necessary.
Step 3: Inspect wiring and connectors for damage, corrosion, or loose connections.
Step 4: Test solenoid resistance with a multimeter (typically 20-40 ohms).
Step 5: Perform a transmission pressure test to confirm solenoid operation.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as the transmission may slip or fail to shift, potentially causing further damage. Limp mode may limit speed and drivability.
How much does it cost to fix?▼
Repair costs range from $150 to $400 depending on labor rates and whether the solenoid is replaced individually or as part of a solenoid pack. Fluid change and diagnostics may add to the cost.
