Gear Shift Lock Solenoid/Actuator Control Circuit A Range/Performance

Where it lives

For P0929, the part to look at first is the solenoid named here.

Check these first

• A shift lock solenoid A that strokes slower than commanded
• Debris restricting the shift lock solenoid A
• A worn shift lock linkage
• A TCM driver fault on the shift lock A circuit

What to do next

1. Read gear shift lock solenoid A command on a scan tool
2. Command the shift lock solenoid A and watch response
3. Inspect the shift lock linkage for wear
4. Measure the shift lock solenoid A resistance
5. Replace the solenoid if the response is off
6. Clear the code and retest
