Shift Solenoid D Stuck On
P0767 indicates that the transmission's Shift Solenoid D is stuck in the ON position, preventing proper gear shifting and transmission operation. This code sets when the PCM detects the solenoid is not responding correctly to command signals, which disrupts the hydraulic pressure needed for smooth gear transitions.
What You Might Notice
- Transmission slipping between gears
- Transmission overheating
- Vehicle stuck in limp mode or reduced power
- Decreased fuel economy
- Check Engine Light illuminated
Most Common Causes
- 1
Faulty Shift Solenoid D
The solenoid valve itself is stuck in the ON position or has failed electrically, preventing normal operation. This is the most common cause of P0767.
- 2
Low or Dirty Transmission Fluid
Insufficient fluid level or contaminated fluid reduces hydraulic pressure and prevents the solenoid from functioning properly. Dirty fluid can also cause the solenoid to stick.
- 3
Clogged Transmission Filter or Restricted Passages
A dirty or clogged transmission filter restricts fluid flow, reducing hydraulic pressure and preventing proper solenoid operation.
- 4
Corroded Wiring or Damaged Connector
Wiring corrosion, loose connections, or damaged connectors to Solenoid D prevent proper electrical signals from reaching the solenoid.
How to Diagnose It
- 1
Check Faulty Shift Solenoid D — The solenoid valve itself is stuck in the ON position or has failed electrically, preventing normal operation. This is the most common cause of P0767.
- 2
Check Low or Dirty Transmission Fluid — Insufficient fluid level or contaminated fluid reduces hydraulic pressure and prevents the solenoid from functioning properly. Dirty fluid can also cause the solenoid to stick.
- 3
Check Clogged Transmission Filter or Restricted Passages — A dirty or clogged transmission filter restricts fluid flow, reducing hydraulic pressure and preventing proper solenoid operation.
- 4
Check Corroded Wiring or Damaged Connector — Wiring corrosion, loose connections, or damaged connectors to Solenoid D prevent proper electrical signals from reaching the solenoid.
How to Fix It
- 1
Replace Shift Solenoid D
Remove the faulty solenoid from the transmission valve body and install a new one. Ensure the connector is clean and properly seated before reinstalling.
- 2
Check and Top Up Transmission Fluid
Check the transmission fluid level with the engine running and transmission in Park on a level surface. Top up with the correct fluid type if low, and replace if dark or burnt-smelling.
- 3
Replace Transmission Filter
Drain the transmission pan, replace the clogged filter with a new one, and refill with fresh transmission fluid. This restores hydraulic pressure for solenoid operation.
- 4
Inspect and Repair Wiring and Connectors
Inspect the solenoid connector and wiring harness for corrosion, loose pins, or damage. Clean corroded connectors with electrical cleaner and reseat connections, or replace damaged wiring.
