Electric/Auxiliary Transmission Fluid Pump A Motor Over Temperature

Where it lives

For P0DE4, the part to look at first is the pump named here.

Check these first

• A transmission fluid pump A motor that is overloaded and overheating
• Low or degraded transmission fluid reducing lubrication
• A blocked fluid pickup or restricted flow to the pump
• A failing pump motor bearing or winding

What to do next

1. Read the pump A motor temperature on a scan tool
2. Check transmission fluid level and condition
3. Inspect the fluid pickup and lines for restriction
4. Command pump A and listen for bearing noise
5. Replace the pump A motor if it keeps overheating
6. Clear the code and retest
