Transmission Friction Element D Stuck On

Check these first

• A friction element D stuck on
• A solenoid or valve holding element D applied
• A blocked fluid passage feeding element D
• Low or degraded transmission fluid
• A TCM calibration fault

What to do next

1. Read friction element D apply data on a scan tool
2. Command the element D off and watch slip
3. Check the fluid level and condition
4. Test the solenoid and valve on element D
5. Repair the element D circuit if it stays applied
6. Clear the code and retest
