Where it lives

For P27C1, start at the solenoid the description names.

Check these first

• A pressure control solenoid P stuck in the off position
• Debris in the pressure control solenoid P valve
• Low transmission fluid pressure at pressure control solenoid P
• A worn pressure control solenoid P bore in the valve body

What to do next

1. Read pressure control solenoid P commanded and actual pressure on a scan tool
2. Compare pressure control solenoid P output through a command sweep
3. Check transmission fluid level and condition
4. Replace pressure control solenoid P if the output stays low
