Where it lives

For P0964, the solenoid sits on the circuit this code reports. The description of P0964 reports the solenoid as open.

Check these first

• A failed pressure control solenoid B
• An open in the pressure control solenoid B circuit
• A poor electrical connection at the solenoid B connector
• A failed transmission control module

What to do next

1. Read pressure control solenoid B data on a scan tool
2. Inspect the pressure control solenoid B connector and wiring
3. Test the solenoid B circuit for open and short faults
4. Compare the commanded and actual line pressure
5. Replace pressure control solenoid B if the circuit tests good
