The P0981 fault code indicates an issue with the Shift Solenoid D Control Circuit, specifically concerning its range or performance. This solenoid is a critical component in the automatic transmission system, as it controls the gear shifting process within the transmission. Anomalies in this circuit can lead to problems in shifting, ultimately affecting the vehicle's drivability.

What are the symptoms of the P0981 code?

Drivers may experience various symptoms if this code is triggered, such as:

• Harsh or erratic shifting
• Inability to shift into certain gears
• Transmission slipping
• Warning lights illuminating on the dashboard, particularly the check engine light
• Increased engine RPM without corresponding speed increase.

What causes the P0981 code?

Common causes of the P0981 code include:

• Faulty shift solenoid D
• Short or open circuit in the electrical wiring
• Poor connection or corrosion in connectors
• Problems with the transmission control module (TCM)
• Low transmission fluid levels or poor fluid condition
• Internal transmission issues affecting solenoid operation.

How to fix P0981?

To resolve the P0981 fault code, technicians typically follow these steps:

• Inspect the wiring and connectors for any signs of damage, corrosion, or loose connections, and repair as necessary.
• Test the shift solenoid D for proper function and replace it if it is faulty.
• Check the transmission fluid level and condition, topping off or replacing the fluid as required.
• If no mechanical issues are found, the TCM may need to be reprogrammed or replaced.
• Clear the fault codes and conduct a test drive to ensure the issue has been resolved.
