Shift Solenoid D Stuck On
The P0767 code indicates that the Powertrain Control Module (PCM) has detected a malfunction in the shift solenoid 'D' circuit, specifically that the solenoid is stuck in the 'on' position. This solenoid controls hydraulic pressure to engage a specific gear in the automatic transmission. When stuck on, it can cause improper gear engagement, harsh shifts, or transmission slippage. The issue may be electrical (wiring, connector, PCM) or mechanical (blocked solenoid valve).
01. Most Common Causes
- Faulty shift solenoid D
- Wiring or connector issues in solenoid circuit
- Low or dirty transmission fluid
- Internal transmission mechanical failure
- Faulty PCM
02. Symptoms You Will Notice
- Check Engine Light on
- Harsh or erratic shifting
- Transmission stuck in one gear
- Decreased fuel economy
- Transmission slipping
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Inspect transmission fluid level and condition; top up or replace if necessary.
Step 3: Visually check wiring and connectors to shift solenoid D for damage or corrosion.
Step 4: Test solenoid resistance with a multimeter (typically 20-40 ohms).
Step 5: Perform a solenoid actuation test using a scan tool to verify operation.
Step 6: If solenoid is faulty, replace it; if wiring is bad, repair as needed.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as it can cause further transmission damage. Limited driving to a repair shop is acceptable if shifting is still possible.
How much does it cost to fix?▼
The cost typically ranges from $150 to $400, including parts (solenoid) and labor. If internal transmission damage is found, costs can be higher.
