- Damaged wiring harness
- Corrosion in the electrical connections
- Faulty shift solenoid 'B'
- Electrical short circuit
- Poor electrical ground connection
Symptoms of P0976 2016 GMC Sierra
- Harsh or delayed shifting
- Erratic transmission behavior
- Transmission slipping
- Illuminated check engine light
- Decreased fuel efficiency
How to Fix P0976 2016 GMC Sierra
- Diagnose the issue by using a scan tool to retrieve the trouble code and inspect the shift solenoid 'B' circuit for any visible damage.
- Test the shift solenoid 'B' for proper operation by applying voltage and checking for a response.
- Inspect the wiring harness for any signs of damage, corrosion, or loose connections. Repair or replace as needed.
- Replace the shift solenoid 'B' if it is found to be faulty.
- Clear the trouble code, reset the transmission adaptions, and test drive the vehicle to ensure proper operation.
