The P0984 fault code indicates an issue with the Shift Solenoid E Control Circuit, specifically related to its range or performance. This solenoid is crucial for the proper shifting of gears in automatic transmissions. If this solenoid is malfunctioning, it could impact the transmission's ability to shift smoothly, leading to drivability issues.

What are the symptoms of the P0984 code?

Symptoms of a P0984 fault code may include:

• Harsh or erratic shifting
• Slipping gears
• Delayed engagement of gears
• Warning lights on the dashboard, such as the Check Engine light
• Poor acceleration or performance while driving

What causes the P0984 code?

Common causes of the P0984 code include:

• Faulty Shift Solenoid E
• Damaged wiring or connectors in the control circuit
• Low transmission fluid levels or contamination
• Malfunctioning Transmission Control Module (TCM)
• Internal transmission issues

How to fix P0984?

To resolve the P0984 code, consider the following fixes:

• Inspect and replace the Shift Solenoid E if it is found to be faulty.
• Check and repair any damaged wiring or connectors in the solenoid control circuit.
• Ensure that the transmission fluid is at the correct level and replace it if it is contaminated.
• Reprogram or replace the Transmission Control Module (TCM) if necessary.
• If internal transmission problems are suspected, a complete inspection and possible overhaul may be required.
