Gear Shift Actuator Temperature Too High

Where it lives

For P2786, start at the actuator the description names.

Check these first

• A failed gear shift actuator temperature sensor
• A dragging gear shift actuator that runs hot
• Low transmission fluid starving the gear shift actuator circuit
• A restricted gear shift actuator cooling circuit

What to do next

1. Read gear shift actuator temperature on a scan tool
2. Check transmission fluid level and condition
3. Inspect the gear shift actuator cooling circuit for restriction
4. Test the gear shift actuator temperature sensor resistance
5. Replace the gear shift actuator temperature sensor if it reads wrong
6. Clear the code and retest
